12GA From Hell

Got some testing done with 12GA FH using
730 gr Dixie Terminator hard slugs..First the gun is 25 lb built on a Savage 210 action,
heavy barrel 31 in long.Stock is full of
lead shot and epoxy in the butt section..
We got 2700 fps top speed with TERMINATOR
lead slugs.No leading..All shooting done with one case to see how they hold up,over 2 dozen
firings and no resizing needed on the bottom
2/3 of the case yet, only size the top 1/3 to
grip bullet..cases fall out of chamber, and I have a minimum 12 gauge chamber as it is tight fit to get regular 12ga shot shell in it.Cases are made from BMG brass
that we put Rims on.Uses BMG primer.John at Bridger
made the rims, and put them on.

Loads done so far with 730 gr Terminator--

230 gr HBMG---1550 fps
280 ge HBMG---2000 fps---21k load

260 gr W860---2200 fps
300 gr W860---2400 fps---27k load

250 gr 7383---2560 fps---35k load..slight comp.

260 gr Magpro-2430 fps
300 gr Magpro-2700 fps---35k load-11,800 ft lbs.

As this crappy weather allows,
Will test 750 gr Bridger bullet; and
A Barnes 3/4 oz sabot(should get 4 grand).

Maybe we can find a way to get a thick walled reciever done to put the Savage bolt, bolt carrier, trigger etc on,with slightly larger
barrel thread..Then it would have safety margin for 50-55k loads.. The 3 lug bolt will hold if in thicker reciever...It is a real super smooth
operating action.

Rob on AR got his going also. His action is a Borchardt
falling block.He got 750 gr Bridger over 3000 fps,
15000 ft lbs energy.He can run full pressures as action
was made for 50 cal BMG.Ed Hubel

back stop is a big banded pallet of slabwood about 6 ft

Check out www.accuratereloading.com for loads for the .700 Nitro Express in a bolt gun. They ran 1,000gr. bullets up to 2,450fps but wwere plagued with hang-fires until they used 2gr. of bullseye to kick the charge off better. They also used .50BMG brass, I believe.

Re: 12GA From Hell

They used regular 700NE cases with mickey
mouse primers, which can hangfire without
bullseye.. With our case built from bmg we have
a primer 3 times as powerful, and it starts
230-320gr of slow powder fine.My 700HE a
long straight belted case, soon to be
tested is built from bmg brass and won't have no
hangfires, and it will add at least 500 more fps,
than the NE.Ed

OK so, in your words, they used mickey-mouse cases, well that makes you even as you are using mickey-mouse bullets - 260gr.- my word! That's too light for my .375 let alone a .73 cal rifle. At least they used 1,000gr. bullets. ;-)
: You say YOUR ctg. is going to get 500fps higher than the 700 Nitor Express?? You're saying you are going to make or beat 2,950fps with a 1,000gr. bullet? That will be something. I'm champing at the bit to see that.

Re: 12GA From Hell

Daryl--my 12ga bullets are 730gr-- The 260 grain
figure is in the range od powder weights.One load
Rob had was 2000 gr.The only light bullet I used in
12ga was a 3/4 oz sabot just to test it
for somebody.Be shooting heavier in couple weeks.
860 gr for somebody, 1100gr later on....
I used that mickey mouse
term because of the marginal primer they have in
the 700 NE relative to the amount of powder.Case
is fine, just primer isn't big enough.....And
everybody has trouble without fast starting powder,
which is a hell of a way to have to do it.
I am telling everybody that has 700NE to put a pocket
in it for bmg primer.They are only little over 20 cents
and it seems out of place to by a 700NE case for
60-100 bucks and not use a big enough primer.
Here we have my lowly Savage at moderate, medium,
pressures. outdoing all the NEs, Nyatis,
TREXs, JDJs, etc..And My 700HE(3.87 in long belted
staight case made from bmg, bmg primer) will be on BMG
rated action and it will get a 1000 grainer over
3000 fps.Ed.

is 470 grains, really streamlined.And
you can buy them by the ton, just cut back
portion that is .510 diameter off, and that leaves front part for a .500 dia bullet,
1.5 inches long..Good for armor plated chucks.First in picture is original
sabot with Barnes 3/4 oz hollowpoint slug.3rd is the 900gr 600NE slug in my sabot made from heavy shotcup. 4th on the miniature digital scale is an older Barnes .580 cal

I picked up a 12ga NEF Ultra Slug gun.24 in shorty barrel.
Added weight and thumbhole stock.
Gun weighted to 15 lbs so
far. I got 600gr hard slug to
1650-1700 so far, and shoots easy.
Got 1 1/2 inch thick pad.Working up different
loads.Should get over 2000.
Cases eject easy,no resizing needed
on bottom half of case,action opens easy,
no evidence of binding.Started case 3.2 inch,
settled on case length of 3.15-- Chamber being
full size max 12ga size expands top half of case
more than my minimum chamber in Savage does,
so little more effort needed to size.Our case, though many times stronger than regular
12ga cases is thinner at mouth, so that is
why I used tight chamber on Savage.Still
can't get used to mickey mouse short barrel.

make long alloy barrel with pivot mounted?

Being some guns(NEF) need to much work

do the following with adapter bushings.
Here is picture of cases for primer
comparisons.1st is regular bmg
primer. 2nd is adapted to a shotgun primer.
3rd is adapted to large rifle primer.
Of the 2 adaptations, large rifle is
easier to do, just ream out pocket, thread in adapter, but adapting shotgun primer
you have to deepen the original primer
pocket a little, then thread and screw in
a bushing.These two primers give about
100 fps less than bmg primer.Ed.

Re: 12GA From Hell

Shot 12 double ought buckshot in 1887.
That's 624 grains worth. Used short
2.45 inch case that feeds from magazine.
Used fast ball powder, getting about
1500 fps. Further testing on 600 gr
hardened slug got 1700.That is in short
20 in barrel. Comparing this short case
with the 3.07 inch case I use in NEF there
is an inch difference in length of powder
column so it takes faster powder with
10k more pressure in 87 to get same velocities as in NEF. But the 1887 handles it fine.
It takes as much pressure as my Savage
in its present form.Ed

Re: 12GA From Hell

I got Rocky Mtn turned 12ga cases, and am
developing loads. They are 2 7/8 inches
long are for use in NEF and shortened
in 1887. These cases have shotgun
primers. Now these cases with shotgun primers and the two cases of ours we put small primers in don't fire the slow rifle powder loads
reliably,like cases with bmg primers.
Our testing is with 600 hardened Dixie slugs.
So I have and am testing slow shotgun powder and fast rifle.I tested 5 shotgun powders and
the primers fires then ok but the quick peak pressure when loads increased to get velocity
wanted in NEF caused too much case expansion just ahead of the base.Cases ejected ok but
that expansion and resizing will ruin cases
in a couple shots.These cases have a real thick base, and are machined to glass smooth finish.Nice cases.
I now testing AA1680 Ball andRE-7 they look good.
Have got loads with 2 wads in
the Rocky Mtn case, and only .002 expansion
of case ahead of base. Will chrono next and
expect it to get velocity we want in NEF.
Nice thing about this testing is that same loads will work in shortened 87 case by just
using less wad column.Ed

Re: 12GA From Hell

Testing Rocky Mtn cases in NEF.Got 1850 fps
with 125 gr AA 1680 and 132gr of RE-7.
Cases are 2.9 after 3 firings. AA 1680
load had .135 card wad and 2 1/2 in lubed felt
wads, and RE-7 load had same card and
a 1/2 and a 1/4 lubed wad. Re-7 less dense.
Base expansion ahead of thick base was
.002 to .003 and resized without huge effort.
The base is .300 thick, case has shotgun primers. By the way I put primers in with
bmg primer post. Work good. Now will cut back
some cases for the 87 levergun.About same
loads used in NEF minus wads should do.
Will get little less velocity in 20 in bbl.
But I will have loads figured out for
a bunch of guys here and in Australia.
I also feel now that have I found loads that
get velocity without a huge expansion, to
the turned cases that good low base plastic
will do the same velocity, in strong alloy
barreled guns. Ed

Re: 12GA From Hell

Good news-First tested 87 levergun.
Using Rocky Mtn cases cut back.Cut case
back to length that feeds from magazine,
2.45 in. That is about max length of any
loaded and crimped 2.75 case.Got 600gr to 1700
with 20 in barrel.120 gr of RE-7.No squib loads.
Cases eject good, expanded a little
ahead of base .003, resize ok.Now the second
good news. Seeing as how these non traditional
powders used in shotgun didn't expand the
turned cases a lot( in our cases made from
bmg brass it took over 10 loads to expand
bases enough to need sizing)............
I figured time to check plastic cases.
Plastic cases took the same load as turned
brass in the NEF.And 100 gr RE-7 in
1887 and we are keeping it down in original barreled
1887 due to plastic cases expanding just
ahead of the rim in two spots due to
extractor cutouts. New barrel will solve
that as we will make cutouts different.
Up to 140 gr RE-7 in NEF. Tested Fed,Win,Rem,
highbase, lowbase, etc. Lowbase extracts easiest.
You who want to get the power that NEF and
1887 are able to deliver use good plastic
cases as a way to get started with
600 gr slugs.You don't need heatreated
for those speeds just hard cast
from wheel wts.. Win AA 2 & 3/4 best for 1887.
It is lowbase and easiest to resize.
To get potential(extra 200 fps) it needs a long barrel.They made long barrels in original.
I used federal 3 inch case in Nef.By the way modern plastic cases have steel bases with
copper plating so they are strong. I tried
one of the fast shotgun powders, that
previously expanded the brass
turned case to much, in plastic cases in
NEF and at 50 gr case was sticking
and had expanded quite a bit, but same
case with 140gr RE-7 popped out easy,
and resized easy.Ed

Re: 12GA From Hell

I'm doing a long chamber in the NEF. Just lengthening
the present 3 inch chamber .The base size of
the regular chamber in NEF is max dimensions,
and in my Savage I have a smaller minimum size.
It wworks grear with long case. So for brass
use in the NEF I honed out a base die bigger to
match NEF size, then it won't over work brass
and it maybe only will need sizing once in every 20 shots, and with the proper fit resizing will be easier.And
my other base die does Savage.Same
top die will do both top halves. Ed

Re: 12GA From Hell

I got the hammer on 87 beefed up to fire big primers.
Still testing plastic and turned cases in 87.
We are testing small primers with 10gr starter powder(Blue
Dot) and RE-7 and 15.Plastic cases max is 90gr RE-7 with
10 gr starter, turned brass case 110gr RE-7 10 gr starter.
WE had to go to starter powder as we was getting
delayed ignition and squib loads.
Testing the cases,plastic and brass with small
primers and starter powder ... A big find. IE, we can't do
this for reliable ignition if the cases
are ballon head, whether plastic or brass.The cases must have the area between side and
the pprimer at least .200 thick.One reason is
strength. And some plastic I have measured is
only about .060 thick there and the protrusion
in the center for primer is .140 above that
thickness.. So 10 gr of starter powder is
in a groove so to speak and not on top of primer!!! That isn't good. I cut the cases
off at the brass base, poured in 10 gr
of flake powder and saw how it laid
in the case. Nice thing is that a most brands of cases are thick enough, like Win AAs.
So far RE-15 and Blue Dot starter looks
very good, and easy on cases.Velocity as good as RE-7.Will keep testing and I ran out of
RE-12 and the shops have no more, So
it will be RE-15 which I think turning
out best, or RE-7 in smaller
amounts.Ed.

Re: 12GA From Hell

Been testing IMR-4759. No ignition problems.
Ignition is instant with regular primers.
Don't need Blue Dot starter powder.
Plastic cases first.600 gr slug. I got a
nice working roll crimper attachment
for drill press for crimping slugs.
That sure makes it easy, and perfect crimp.
In 2 & 3/4 plastic cases with loaded
length of about 2.35 inches got to 80gr.
That's max as you must leave room for
about 3/8 wads or cushion wad. Some cases
may only hold 75 grains max due to
the case construction.Powder is less dense
than RE-15. 1650 plus fps in 24 inch barrel.
In 3 inch cases, loaded length about 2.6
inches, got to 95 grs max, 1800 plus fps.
Some cases may only hold 90 gr due to
case construction. Cushion is
a half inch felt wad or equivalent.
Both lengths start down and go up
if pressures allow. 60 gr short case,70 long.
This powder being faster than RE-15 you must
have a little cushion in the way of felt wads
or plastic cushion wads.With slower RE-15
a card wad works ok as powder started slower.
The powder burning must build pressure
to open crimp with out a high pressure spike.
This bulky powder with reliable ignition
is a winner.Then we tested 3" Rocky Mtn brass
cases, Got max load of 105 gr, and 1900 plus
fps. In few weeks will get the 4759 and RE-15
loads pressure tested.Ed

Now these loads are for only heavy barreled
steel action guns like the NEF Ultra 12,
or like my Savage with heavy barrel added.
I am getting heavy barrel on the 87 and
it will be long.There are some turn bolt
locking lug pumpguns that would work
with heavy barrels.There is a large
12ga Tula bolt action, but it's not imported.

about 100k. That's not a missprint.Their
site shows testing at the Italian proof house
of 8000 bar.That's 7-8 times regular shotgun

Well in Nef the REM factory Buckhammer
slug load, expands the base of the case
more than my 90gr, 4759 load. And I get

Re: 12GA From Hell

Hot Damn- Test Results of 4 plastic cases.
Rem high base 3" case, with 600 gr
Dixie hardened slug. Roll crimped with
crimper in drill press. All 4 loaded with
90 gr of 4759. We have a winner.
Average velocity of 4 -- 1938 fps
Average pressure of 4 -- 14, 575 psi.
tested with transducer test ing setup,
in 30 inch barrel,In my 24" NEF I got 1800+.
Cases fell out of his test chamber like they did out of my NEF.And with some cases I can get in 95gr, that I figured with my math would
have 15k psi.So my math and developement is
OK.And 4800 ft lbs, thats neat with plastic.
Tom says this load will do in any gun that handles
the 2 oz factory magnum goose loads
that test about 13,600 to 14,000.And 4759
will give slower time to peak pressure, thus
will be easier on cases than magnum goose loads
or the hot factory Buckhamer slug loads
I fired, that expanded cases as much or more
tham our 4759 loads.Ed

Re: 12GA From Hell

Some research. Anyone with a Mauser converted
to 12ga shotgun can fire our 4759 loads.
One was the GEHA, other REMO. The locking lug for bolt is the rear safety lug and if you wanted an extra lug do an Ed on the bolt
handle base to make contact between bolt handle and bolt handle recess.They are not long enough
for our full length case, but came with 2 3/4"
chamber and magazine.Were 2 shot large ring
converted military mausers.Studying this gun lead me to the idea that a fancy 12ga with 3" chamber could be made by the same thing that Germans did to the Mauser to make GEHA. Just use
a S&L, Colt Sauer, etc, with rear locking lugs.
Grind out inside diameter of action from rear reciever forward so 12ga case will feed, Rear of bolt will still center ok as lugs and metal
are there. The silver solder combination guide extension to support 12ga case on the left side
of bolt, and put extractor on right side.
Like a Sako or whatever.Face off the recess on front off bolt flat, Put in 12ga barrel with chamfers to clear extractor.A 788 Rem
may work, at least with a 2.75" case.
For repeater action, Open mag
well to hold a single stack of 1 or 2
12ga cases.Fancy gunwrighters badmouthed
the GEHA, but geese hunters just loved them,
as they handled heavy loads fine. Ed.

Re: 12GA From Hell

Here is picture of top part of the
first scale-up model, next to smaller
Wickliffe. It has 12GA FH round in feed
trough. It is aluminum just for a model.
It will handle 12GA FH, 700HE, 700NE, 600NE,
etc. Bottom of block is flat to set on
mill table to do the machining.Next machining
will be the hole and slot down through the
action for breech block and hammer to
slide up and down in.Its taken awhile to
get some tooling.I had none when we set up
vertical mill, and have to get more.The
action model also will be narrowed up when
finished, and contoured to look as good
as the Wickcliffe.Ed.

Re: 12GA From Hell

Tested the Wickcliffe with 12ga FH case
in a temperary chamber to see if
hammer with beefed up spring would fire
bmg primers.I scalloped out the back
of the action so 12ga cases would feed
into the action and temp chamber
They fired ok. Bur the extra stiff spring
makes it hard to cock. We will have to work
on that.The original Wickcliffe
action that we want to scale up is tall
enough so that when breech block is
lowered the block clears the bottom
a 12ga rim when cases slide out of chamber.
So in the scale up we need to just add a
a little width for wider breech block,
and the bigger barrel thread, and keep the
sides thick for strength.Ed

In response to guys who can't find 4759

Tested 2 fast stick powders, 4198 and 4227.
Both didn't ignite good with small primers

Re: 12GA From Hell

Fired couple 3.5" cases with 90gr
4759 and 460 grains of buckshot,
14 number 1 buckshot.Fired in nef,
pattern huge due to rifling, even with
shotcup. They were going 2000 fps plus,
and went through 1/8 steel on end of
stand. Ignition perfect, extracted easy.
In smoothbore be a real hairy load.
With three 3.5" plastic cases with
100gr 4759, 600gr slug. Used .135 card wad,
a 1/2" and 1/4" felt wads. 1900+ fps
in 24" NEF barrel, same low pressure as
the 3" cases we pressure tested. I have NEF
chamber lengthened for our longer
brass case. A nice long barrel we'd
have 2050 plus.
On the scaleup model solved the hard cocking
problem by usinf NEF hammer mounted in a
lengthened breech block. It pivots h\behind
the toggle pin and is taller so it cocks easy
even though it has doubled the springs
to fire big primers.Ed

Re: 12GA From Hell

Here is pictures of the breech, lever,
linkage, etc, set up on a block to
get the geometry for the scaleup model working
ok.And setup measurements to make the breech
hole in the action, in right place.Also used
this model to get hammer and trigger set
up to ride on the breech block. With
a strong hammer and trigger in the right
place in the guard.In the pics above you see the pin the
lever pivots on. The actions being bigger
will be wider than the levers;So the space on the
pivot will be taken up by the Ruger
style extractor on the left side and a spacer
on the right side. Spacer also acts as a
breech block stop at the bottom of the
breech travel.So to get block stopped at
right position for the diameter of the case
and feed trough, we adjust spacer size.
Ruger extractors from GP changed
a little bit will do.Ed.

Founf info an a double that would work

No. 6 HG on trigger guard. It is over 2 & 3/4"
across outside of both barrels, chopperlump
barrel pivots, with heavy locking lugs,
and A purdey style third fastener.Top lever.
Barrels are big enough to use as monoblocks
to screw in heavy 12ga barrels, with same size

could handle same loads as the Savage.Like

Asked about using 900 gr saboted bullets in

With bullets that heavy you'd have too
high of pressures with 4759
for plastic cases. Possibly could do
it with RL-15 and starter
powder in plastic, but only
in heavy barreled like NEF.

But the 600 gr Dixie is still the best for
most uses in plastic.

A NEF and brass RMC cases would handle 900 gr
Saboted bullet with RL-15 and starter powder. Start
at 80 gr Rl-15 and go up if cases don't
expand to much to resize.Ed

More VV N-110 testing that we got done.
Starting loads are 60 gr min like 4759 for good
ignition,600gr slug. In 2 & 3/4" plastic full load is 75gr
with card and 1/4" cushion wad.In Nef 24" bbl 1700fps.
In 3" plastic 87gr, card and 3/8" wad, 1800 plus.
In RMC brass case. 100gr, card and 1/2 wad 1900 plus.
All running same safe pressures as 4759 lab tested.
So that is two powders that are slower than shotgun
powders, and much safer to work with for regular
primers, giving at least 20% more velocity. Ed

Along with the two slower than shotgun powders, IMR 4759

that are easier to load for slugs, in heavy bbl can
get 20% plus more velocity, I've found another. It is
IMR 7383 $3 a lb surplus. Tested plastic 3" cases, perfect
ignition with regular primers. 8 types of cases,600gr slug
starting load 100gr. Full load 140gr giving 1800 fps plus
in 24" bbl NEF.With loads halfway between start and full
didn't even have to resize to shoot again.Full load just has
a card wad under slug in 3" plastic.Wad just tight on
charge, as no extreme compression of powder needed.

Re: 12GA From Hell

Tested 730 gr with 7383,Perfect ignition.
Plastic 3" cases, different brands.
130gr gives 1650 plus fps. Extracts easy.
Tested 800g slug with 7383 in plastic.Works good.
Have question about different cases and dies.
The RMC cases use a shotgun primer, thus they have
a real thick base. They are not a thin headed,
balloon headed case, and RMC makes sides thick
enough for regular 12ga wads.
But in a break action the 3" plastic cases
with our 4759, VV110, 7383 loads are close to RMC in
power. Can buy a hundred plastic for price of one RMC.
3.5" chamber 12ga with plastic is as good as RMC for 3"
And if I shot RMC in Savage to get more power,
which I could do as far as the firing process,
the expansion above the base, due to being a turned case
would make extraction stiff, causing extractor to
damage rim. A turned rim will not take what
a drawn one will. Rcbs set should do RMC easy.Ed

Re: 12GA From Hell

Here is a simple outline of what we've done with
our project we call the 12GA From Hell.
Some folks have asked us to do this.

A. The idea for this and the name was by
Robgunbuilder on the AR forum. We figured out how
to make a long brass case, from BMG brass by
machining rims and the case to screw them on.
We ended up with case after mouth was
annealed, fireformed, and expanded to 12ga,
that was 3.85" long, with a big BMG primer.

B. Rob put his in a big Borchardt falling block,
a gun that can take full BMG type pressures.
It had firing mechanision that fired primers ok.
Example top load is a 1000gr turned brass slug at
3100 plus fps, and a 7/8oz 12ga sabot at
4300 fps.

C. First of mine in a Savage 210 bolt shotgun with a
heavy rifled 31" barrel. My loads in this were kept
below 35,000 psi. Giving loads of 2700 fps with
a 730 gr hard lead slug, and 3900 with 3/4oz sabot.
Second gun was a NEF Ultra that I lengthened chamber
to take long case. Top loads are 600gr hard slug
at 2500 plus fps.Both Savage and NEF had to have
firing mechanisions beefed up to fire BMG primers.

D. We cut cases back to use in 3" chambers but
all guns have to have beefed up hammers, etc,
to fire the big BMG primers.The BMG primers
fired the slow rifle powders ROB and I
were using very well, no misfires.
So tried 3" RMC brass cases, regular plastic cases,
our cut back cases with primer bushings, all with
smaller regular rifle or shotgun primers,
that regular hammers or firing pins fire ok,
and found out that our slow rifle powder loads
wouldn't fire reliably with small primers.
The slow powders in large diameter cases
needed BMG primers to work. So to use small primers-

E. We went to much more research. We found that
slow powders could be fired with a 10 gr of a
fast shotgun starter powder, under the slow powder,
using small primers. This concept has beeen
used in NE cases. We also searched for rifle
or pistol powders slower than shotgun powders,
that would fire with small primers and no starter,
that didn't up peak pressure to fast as
we increased loads to increase velocity.
We didn't want to over expand RMC brass or
blow out the rims on regular plastic cases
We found three- IMR 4759, VV-N110, and 7383 surplus.
These powders are easier to load for slugs without
the problems of fast shotgun powders pushing up
the peak pressures to quick, as you try to increase
loads to up the velocity. We use a minimum
thickness overpowder wad or other wads in the loads
under the slugs as needed. We had lab test 4759
loads with 600gr slug and pressures were little less
than the magnum REM Buckhammer factory loads, but
we got 400 fps more velocity. The Buckhammer
slug and locked on wad is about 600 gr.Both our tested
loads and Rem loads are 3" plastic.Our loads are for heavy
barreled guns only. IE; all slow powder loads whether
with starter powder or 4759,N110, 7383, use heavy barrels,
as the pressure curve is higher down the barrel
and might split regular skinny shotgun barrels.

F. We plan on heavy barrels for testing 1887 Win
leverguns, for Mossberg 695 bolt guns, for
various heavy double shotguns, for various
O/U, for modern alloy guns, etc.We are helping to
design a big falling block for 12ga diameter
that can take high full load pressures,
that is reasonably priced.. We plan on testing
other powders, for use with small primers. We
plan on setting up pressure testing barrel for
the long 3.85" case, to test the whole range
of slow powders and bullet weights, in the future.
The testing lab now can only do 3" 12ga cases.
We have found heatreated Dixie slugs that can
take super velocities, we found brass slugs with
relieved grooves that run same pressures as lead,
or copper jacketed, at same velocities.
We found 7383 powder pushes 870gr safely, full loads,
in 3 inch plastic, RMC 3" brass, etc cases.
This research and work is super great fun,
we are glad to share.We will get pictures soon of
the muzzle blast with long case, and pics
of penetration tests. Ed

Re: 12GA From Hell

Found another powder that works with small
primers in plastic and RMC cases. 600gr slug.
It is IMR 4227. Ignition perfect, same load
levels and velocities as 4759. My earlier
report of 4227 not working was in error
due to what looks like 4198 in a jug
hand labeled 4227 I got in sale years ago.
Greg told me 4227 worked for him so I got new
jug, and saw the difference from jug I had.

So slower than shotgun, powders that ignite
properly; we have 4759, VV-110, 4227, 7383 surplus,
the latter a slow powder that works with
real heavy slugs also. Ed

Re: 12GA From Hell

Pressure tested 7383 with heavy powder load.
870 gr with 128 gr of 7383-- All that could
be put in REM plastic and keep length to what
would feed from magazine of a 3" gun,
after it was roll crimped with tool in drillpress.
1513 fps-- 14700 psi. That is a slug 50%
heavier than factory Buckhammer at little
faster speed and at little less pressure.
Ignition perfect, cases fall out.
Love that $3 a lb powder.Ed

You mentioned a while ago that you were looking for a long 12 ga rifled barrel, I just imported one from Pac-Nor, I think you would probably know about them, they should be able to make them 30" + for you.

Got 2000 fps and still able to extract case.

Could use RL-22, Rl-25, Retumbo, etc.

has to get couple pieces of punch and die
tooling to make them .729" to fit most rifled

for you to send the them to him..Here is pic

We will test 4227 with the same slug , and saboted slug

10GA FH info.Fed factory hollowbase slug is .025" smaller than

hollow base. With 7383 that gave another 150 fps.Fast starting
shotgun powders expand base better than much slower 7383.

Re: 12GA From Hell

Ed,

While I read all of your posts because the idea of powerful rifles fascinates me (though I am not happy with recoil and prefer to shoot my very pedestrian 8mm and 30-06 instead) I rarely post because I don't know as much about ballistics as most members do. I have only recently begun to work on handloading and have ordered equipment with the advice of members here, for example.

My question to you is, do you think that your 12 GAFH could be made into a double rifle? At the kinds of enormous power levels that you have worked out from it, if this were possible, you just might have the most powerful double rifle round around. Just speculating here - if this is a stupid question, my apologies are ready in advance.

Good hunting!

Yes you can build a heavy barreled double, with barrels
as heavy as used on the NEF Ultra Slug gun.
The diameter needed for our slower powder 12ga loads, is
1.20" at the breech and 1.050" at muzzle. I have a
Zabala 10ga double that if I get time and money I want to
build a heavy barreled 12 ga bore gun. Like a 700NE only
our cases is longer and .029" more bore. But getting one
done is really expensive.And even 12ga doubles that are
premium, I haven't seen any with heavy enough muzzles.Ed

i got a toy gun from holts auction, in 12 gauge with an action that was so overbuildt that it looks like a 12 with 20 tubes. so i wanted to monoblock it anyways but then i saw your tread again and got a bit hot under the collar, i will do the mesaurments when it comes home and see about barrels etc it looks so fun i think dieter horneber could do a few cases as well, allthough i dont think i will do a full 3.87" a nice 3" would do nicely .
something like a paradox on steroids.

best regards

I would be keen on some 3in brass shells if you are getting some made ,let me know on them !
Have a look at my 12 Bore rifle under "J&W Tolly 12 Bore Rifles Photos" post ,looks a bit like steroid uses

Re: 12GA From Hell

hi sarge

as soon as i get a price i will let you know, and yes i love your rifle. talk about 12 gauge on steriods wauw. i bet it will fun to shoot when you get the loads right

ed could you recommend a load with as low pressure as possible what im looking for is:

750 grn. fosbury style projectile.

3 " brass case.

around 2100-2200 fps

hopefully under the 3000 bar limit

im trying to see if my friend and his cnc lathe could do some steel tips that i could try to cast into the fosbury form, so i could get fosbury hollow points and steel inserts as solids for some fun hunting and tests.

Re: 12GA From Hell

You can get heavy base turned cases from MRC in any length.
For a 750 gr that fast you have too high pressure for double.
Using 3.5 inch plastic I got a 600gr to over 2000 in heavy barrel
NEF, and cases stick and won't extract when I went higher.
You can probably get to 1800 depending on extraction, with 750gr.
If you can find drawn cases without balloon heads that is best.
Personally after all research and getting cases around, if
I do a gun without going the full 3.85" length, I will do them
in 3.5" plastic, it is just so much easier and saves money,
and 3.5 inch plastic wil lkeep up with 3" brass. Ed

Re: 12GA From Hell

That's rather interesting, Marrakai. Perhaps the standard shotgun NEF can handle it, however they aren't the same action as the centrefire rifles, however- according to NEF.
; Whether there is a differnce in design or material or both, I don't know.

Re: 12GA From Hell

The newer 10ga and 12ga Ultra NEFs are the SB2 strong action just like their
big bore rifles. The only difference is shotgun has a larger diameter
firing pin. The SB2 is an investment cast, properly heat treated,
action like a Ruger 77 bolt gun. And it is almost twice as strong as the
SB1 action they make, for their 12ga Pardner series, their 20 ga Ultra,
and various others.I have both 10 and 12ga on SB2 and so far they've
taken a beating and are still tight.And the 12 has a thumbhole stock
and weighted to 15 lbs and it even handles 600 gr at 2500, from
long brass case, that fits in the lengthened chamber.Ed

28GA FH testing. 405 gr in 2.75" plastic case
got 1400. Tested the Great Plains 54cal
lubed slug, runs from 2200 to 2700. It is
by Hornady and its front band actually measures
.550" and hollowbase. They hit target straight.
Got a bunch of 415gr hollowbase coming that
are 548" from Dixie Gunworks. Only 26 cents each.
All will work in plastic or long brass
case. I found another .550 bbl and coming, and
it will go on a Mossberg bolt action
for the second 28GA FH to test.. Ed

Re: 12GA From Hell

Tested the 415 gr hollowbase slugs in 28GA FH long
brass case. These are ones that Dixie Gunworks sell
that they call their Sharps .548" slug. They all run
about .008 bigger than that so they make perfect tight
fit for .550" barrel, and I used a good lube on them
in the grooves. Same speeds as above for GPs.
They are a little harder alloy slug than
the Powerbelts or Great Plains The 28ga shellholder
for our Lee, Lyman, Rcbs presses , we use, is from
RCBS for regular metallic press rams. For 28ga dies
Hollywood made some for metallic presses.Also for
sizing for bottom 2/3 of the brass case you can cut
top off of the 500J die.The slower powder loads don't
even have to have the bottom half sized, which
is great for a turned case. If we had drawn brass cases
we could get 11,000 ft lbs, in the Enfield, which we
don't really need for deer. 4-6000 ft lbs ok/deer ..Ed

1 oz Brenneke KO slug to 2700 with 4227

THE 8GA FH BELLERED TODAY. It is in Enfield I rigged with
rear locking bolt lugs. 32" barrel, tested 3.3" plastic cases.
Cases are the REM kiln gun cases. With the double cup base.
I shaved base a little so that chamber will fire these as well as
regular 8ga plastic. None of the firing today expanded base cups
at all, so they are real strong cases. Started testing to check
ignition with shotgun primers and to see if cases are any
good. Starting with a 110 gr mouse ball, wad under it, and 150 gr
of Blue Dot, about 5000 fps.. Gun didn't even recoil.Then a
410 gr one at 3000 fps, Then a 770 gr hollowbase slug in a wadcup
up to 2000 so far with 180gr of 7383. Barrel is smoothbore .832"
bore at the muzzle. Ed

Re: 12GA From Hell

5744 is used a lot in large cases with partial filling of
cases with powder. But you can't fill the large cases to
90-100% as pressure climbs to much in big cases

Others tested 5744 and it is ok up so far. Shotgun cases are
in the realm of large cases. It works with wads,
to take up air space ok, but you can only get half the weight
of 4759 or 4227 loads before peak pressures are too high
above the limit that we want, which is about 15000 psi in
12ga.And still not get velocities that 4759 and 4227 get.Ed

18/04/08 01:30 AM
Re: 12GA From Hell

I understand. So far 4759 seems to be the only powder that will make 2,500fps in the big "8". This is unfortunate, as that is only in the ballistic range you've accomplished in the 12 bore. I would have thought this ctg. would make 2,500fps with a 1,500gr. slug. A little much for deer, but a great comfort with a charging brown bear. The shot would knock you out of the way, and quite likely stop a charge even if not a lethal hit.

Re: 12GA From Hell

The gun is the limiting factor. If we had big bolt gun, front
lugs, we could get 770 gr to 3000+, 1050 gr to 2700+ in plastic.
A brass case could do more.But it's not bad for plastic.

I also have two other cartridges with my name
on them that I am promoting. They are my 700HE
and my 585BHE. They both belted straight cases.
Montana Rifle company is coming out with their
big PH action and some guys will be doing my
cases in them.
Info on the 585BHE. It will work in
any gun that handles 505 Gibbs like Enfield, CZ,
Ruger,etc.Mine is in Enfield.Here is picture of
of one next to Trex. And mine holds 15gr more
powder than that Trex case. 585BHE will do 750
grain from 1800 to 2800 fps in my Enfield.
Anyone interested setting up a gun, contact me
I will furnish reamer and 15 free cases. Cases are
headstamped. When done return reamer to me, for
the next guy. I will keep them sharpened. After a
few guys have guns we all will get together with
others wanting some and get a run of brass made.
These cases are all drawn high pressure brass.
I'd like guys to ask for reamer when gun is going
to be ready to chamber, that way reamers get the
most guns done in shortest time.Ed

Re: 12GA From Hell

Ed - some time ago, Les Bauska used to make up overly-large Ruger-style #1 Actions chambered for the .600 Nitro. A note to his son might shed some light on this for action size, rim size allowance, etc, and if the outfit who cast the actions for Les is still in operation. A huge #1 Action would make a fine modern 8 bore me thinks - kinda like so many English guns, but hammerless, of course.

Very interesting idea, but the weight would likely be unreal based on the heavy barrel diameter(thinking diameter of heavy barrel NEF), plus an action large enough for the barrel size AND strong enough for the pressure. Unless someone knows of an existing double that fills the bill a double, as interesting as it would be, would probably be a "from scratch" gun.

First I bought a 1.5 inch dia 4130 alloy, heat treated, shaft,
32" long. Then I had a deep hole drilling company drill
a .832" hole in it. Came out centered on both ends.
Then after it got here I used cylinder hone to polish
the inside of the bore. Threaded it, chambered it, and put
in the Enfield bolt action. The heat treating it had was just like
the barrel stock that barrel guys get. Ed.

Re: 12GA From Hell

Gotta hand it to you, you're very serious about this stuff.

I used to like to get kicked around by big guns, but since coming down with torn cartelage in my right shoulder, front and back, I've lost some of the "belt me if you can" attitude. Dr's who know shooting, think it's the kicking from certain postions that has exacerbated damage caused by pulling my own shoulder back into joint a number of times. Got to the point all I had to do was to reach back over my shoudler and it would pop out - not good. Which came first, chicken or the egg? I say all of this only as a warning to those too tough to wear protection when shooting kickers.

Right now, my little guns are all I can shoot, up to the little medium, the 9.3x57 - and that wearing a magnum recoil protector and only for 10 shots. Really crimping my shooting, but pain is a limiter for sure.

this fall, It is 12ga bore rider design Body is Aluminum, and it
will have a heavy 50 cal insert in the nose made from tungsten
or similiar metals. In the picture he put a 50 cal bullet in for
show. The insert in the nose will be flush with front of the
AL carrier. It should be stable at slow twists and if built
with back and front same diameter stable in smoothbores.
The long lighter tail-end compared to heavy nose insert
will make it stable. Same principle Brenekke uses. This idea

from 12ga, with heavy, hard insert in the nose.Ed

Here is picture of a dart type 12ga slug Rob made. Body
is aluminum, it has a heavy tungsten carbide insert in the
nose. The TC in the nose is about 5 times denser than AL.
Total length is 2.35 inches, weight about 950 gr. The .75" long
insert a real tight type fit. Heat AL, put in insert, cools, locks on.
It is fairly streamlined, yet has wide meplat for penetration
in game. Flat points penetrate straighter in game.
It is hollow inside in the back, behind insert which puts the
center of gravity way up front, it should fly straight even from
a smoothbore. They are fast to make and material
less expense than copper.In pic is a copper and a brass 600
cal slugs for comparison. Dart/slug on right has insert.Ed

Huvius- The back is solid. Rob drilled hole in the front to within
1/4" of base. Hole was 7/16" then he drilled 1/2} hole in
3/4" and put in insert, against step. Idea of aluminum and hollow
inside is to get front heavy projectile stable at slow twists or
in smooth barrels.

Re: 12GA From Hell

Here are more samples of nice 12ga slugs.....Here is pic of
ones RG Henson sent. Jacketed 12ga. 715gr hollowpoints,
on the right and in front a jkt 675gr hollowbase.
RG's number 1-770-366-4846. These will be great for
shorter plastic and brass cases as well as long cases.
Other slugs in pic, in the back, left to right
Foster 436gr- Dixie 600gr- 750gr brass- my 750gr hollowbase
brass, and a hollowpoint I put a lightweight filler in the nose
for streamlining..Ed

Re: 12GA From Hell

Two other 12ga slugs RG may do later on are full
jacketed ones. If interested in the hp one above
contact him at number above. He has to do a bunch
of them to get ahead to do others.And they will be
a fantastic deer, hog, bear slug. He is in Georgia.
Also, any of you who might want some of the 12GA FH
brass cases made from BMG brass, we have the fellow who
had the idea about the 12GA FH first, Rob on AR forum,
is planning on making them. He has got the machines to do
it now, that we didn't have before. Let me know how many
you are interested in getting, so he can plan and figure
the best price. He has a bunch of BMG cases to start with,
he and I have places to get more.I'm posting this all over.Ed

Testing 715gr jacketed hollowpoint from RG Henson in Savage 210.
With 30 inch barrel, long brass 3.85" case, big primer.
Slightly hairy load 290gr RL22--2700 fps. Shot moderate load
of 300gr W-860 -- 2400 fps for 3 shot group of 3" at 50
yards with my bad eyes and peep sights. They shoot nice, they go
into target straight.. Other nice thing the price from RG,
for customers getting in on his first run, $1.25 plus shipping.
That is less than half of what other big bore jkt bullets cost.
Call him for some great slugs. They are great like
the Dixie slugs. Ed

Re: 12GA From Hell

Lookee what another santa sent me.
A regular BMG case on the left, and
a straight BMG case on the right, and it
CAME FROM THE MANUFACTURER THAT WAY.

It is primer cartridge for large guns and howitzers.
It is used in those guns/cannons that have powder in big bags.
It is filled with powder and inserted into cannon breach and
when fired sets off the larger charge. On some cannon breaches
they have an automatic feed for these with a huge 40 round
drum magazine. This on is marked IVI 89 C67. IVI is Canadian.
On these breaches it is held by collet fingers for head space
and for ejection.

Ok, there are many thousands more of these out there than the
PROP cases I showed before. We need to find few barrels of these
and have Rob, etal, put on rims.... no annealing.....no fireforming,
just slight resize to 12GA FH. Please help if you know of any.
They would save so much work and time..And even though fired
the bases are perfectly straight, another plus.....Ed

13/10/08 02:05 PM
Re: 12GA From Hell

Stock 210 load- 600gr Dixie hard lead, 3" case,
use 75Gr of 4227gr for about 1500 fps.Now if heavier
barrel you can do more or if chamberlenthened do more.
Please notice in the picture above, cases loaded with
the 715 gr jacketed slugs, the 3rd and 4th ones.
They both have same 90gr of 4227, same number of
wads, shoot at 1700 in 24" NEF barrel. 3rd plastic is
3.5" case, the 4th brass is a 3" RMC. Both have shotgun
primers.The 5th longer case is a 3.5" strong
brass one I made from a PROP case, and when I put
in primer bushing, I set it up for shotgun primer. I
will test it with 4227 powder, 600gr and 715 gr slugs.
Also in a couple months Rob, who's idea the 12GA FH
was will be able to deliver the super strong 12GA FH
cases made from BMG brass. And the they will be
headstamped, all done by his CNC machine.Ed

Re: 12GA From Hell

RIP on AR Big bore forum is doing 835 Mossy and 1400gr Darwin slugs.
A 14.5 pound Ulti-Mag. The hollow part of the butt is filled with about 5.5 lbs of lead shot and epoxy. Has 4X Sightron in QRW rings. Do 3.5" plastic hulls with the Darwin in it first. It balances on the trigger. Loading the magazine with 4 and one up the spout will add about 1.25 pounds if the 5 rounds are "Darwins," and move the balance point to the front of the triggerguard.
It is heavier rifled 24" chromoly alloy barrel.

Brett in MN has Mossy 835, only with smoothbore barrel and gets
1oz finned plastic tail Ballistic Products slug to 2300 fps,
using shotgun powder.

One and two are 1015gr hollowbase. Three and 4 are

I'm surprised the .50's fit properly. The walls of the 'sabot' are very thick. I think I'd rather have a 12 bore slug fired from a 12 bore. Why cut power and turn it into a .50 Sharps shooting light bullets?

Re: 12GA From Hell

A lot of shotgun only hunters want fast light bullets, with less recoil.
And a little longer range. Still will have good ME.Sabot speeds below.
I like 600gr Dixie and but test everything so guys know about them.
Been testing the Encore with the Nef loads. Barrel breech is
one inch same as muzzle, where the NEF is 1.200".
It has dovetails cut out in bottom of the barrel for
the nuts for the forearm screws. ... At the bottom of dove tail
there is only .060" thickness. Before reaming had back one fill
welded as it was where the taper for the forcing cone ended up
with 3.5" chamber. I load it with 10 gr less powder than the NEF
on all different slugs and weights. Like the BPI sabot in 3.5"
plastic in NEF, 437 gr slug, 120gr 4227, 2400 fps, and in Encore
110gr 4227, 2270 fps. In 3.5" RMC brass case, same sabot/slug
in NEF 140gr 4227, 2600+ fps,Encore 130gr 4227, 2500.
The Encore is now 12 lbs, with hollow in butt and recesses in
forearm with lead shot.In pic you see NEF And Encore with RMC
brass cases started in chambers. Ed

I think I very much prefer the NEF. TC has alwasy had difficulty with screw and ovetail depths - getting them too deep is a common TC problem- modern or muzzleloading guns allthe way back to 1970. Seems things haven't changed much with them. The warrantees are great - goos thing cause almost all their guns need warrantee work. I guess I seem to not like TC very much. Sorry - just my opinion, of course.

a little plastic in forearm, screwed it on, works good....
See what's possible, original Savage 210 action/stock
the one I have our long case in. You can lengthen
magazine in the plastic stock for up to 3.5" RMC brass
cases, also 3.5" plastic cases. And you can open up
bottom of the action to match, and the other things
I did on the port, bolt travel, etc to feed cases.
I did mine with heavy wood stock in singleshot.
Using original plastic stock you weight the hollow butt.
Trigger assembly on these is back to leave space for this.
In picture you see stock original and stock mag longer.
Second picture is a 3.5" brass case and slug overall
length 3.7", in longer magazine. Brett in MN, who did this
first used the regular follower and mag spring ok,
it feeds ok for him. .. Ed

Re: 12GA From Hell

THe A-Bolt is almost as strong, handle all of our long
case loads. Wish they weren't so pricy. They look nice
and have nice style, like a big bore African gun.
Info to help loading BPI sabots in plastic,ok to use plastic
overwad over powder, but should use cardboard card and
nitro wads above that below the BPI sabot. Sabot doesn't
tear up and accuracy much better. Personally I use
cards over powder and nitro wads, And with used cases
roll crimping onto the thin edge of sabot is uneven, so with
my used cases I set the sabot and slug to right height and
just redo the 6 point star crimp real hard, and the middle of
all the crimp sectors set right on the flat nose of the slug
in the sabot. I also do the same with RG's 715gr hollowpoint
with the crimp sectors right on the hollowpoint in used cases.
Roll crimping holds RG's slug in ok but its taper of the ogive and
smoothness it doesn't open crimp all the way around when
fired. The star crimp set slug at same height so you can get
the same amount of powder. With RMC brass these are not
problems but with brass to get good feeding from mag rounding
front edge of mouth helps. Sectioned picture of RMC on right
next to our long original case to show how well it is built
thick and strong. One of cases has 20 firings, still good..Ed

Re: 12GA From Hell

What others are doing hopping up loads and experimenting.
Brett in MN uses a Mossy 835 12ga smoothbore turkey gun, but
it is backbored 10ga size all the way out to end and has 10ga size
choke, and he uses 12ga AQ 441gr slug with locked on basewad, from
BPI. Using top rib bead sight only he can hit a pail 5 times in a row at
70 yds.Amazing accuracy for overbored barrel. He uses BPI X12X seal
plastic wad, two 1/4" white felt wads, thin card then the AQ slug,
with 65gr of Longshot getting 2200 fps. 3.5" new cases with
roll crimp.......I asked him check it with a scope on it sometime.

NFG from Greybeard and Shotgunworld with pump Mossy and 18.5"
with slug barrel. He gets a 525gr Lyman over 1800 fps with
80gr of 4759/4227 powder. Hard alloy mix Lyman and shot one through
17" of pine. Shown in the pic below it mushroomed to .800" and only
lost 8gr weight. It is a wasp waisted slug that is shot from a 12ga
regular WW12 shotcup. The skirt of the slug collapsed into the underside
of the nose. Many guys say that these are as accurate as most
other stuff used. He used 3" plastic, PGS wad over powder and
WW12 wadcup with slug it. He cuts wadcup petals back to length
of the Lyman.In pic on left you see the Lymans with hollowbase up
and the shape of it when starting out.

Ok I am going to get Lymans to test and Longshot to test.
Got to see if the Longshot will get further up in velocity
than Blue Dot. Ed

Re: 12GA From Hell

Ed - I was sent some 525gr. Lyman's along with some wads and 9.3" bullets for testing, from a friend in Alberta. As yet, I've not tried the Lyman slugs, but have some loaded for testing in 2 3/4" hulls. They are cast of WW metal and weigh 506gr. Av. They do fit perfectly inside a Red WW field wad. From the looks of them, I think I may also have to buy that mould for my own use. They might 'convert' me from round balls for my camp 'bear' gun - might! The round balls in WW metal are almost unstopable and somewhat heaveir than the Lyman slug. Alan M. says the Lyman is very accurate in his side by side 12 as in 3" to 4" at 50 yards. It certainly looks promising and is very easily loaded.

That's nice thing about them, easy to load and in the cup they
don't lead the barrel. Slug and wad don't look like much
but lot of guys say they are accurate.
Here is a Savage 210 with bottom of action opened up
toward the back, to take cases with 3.5" overall length.
Slug Warrior on Shotgun World did it. Is similiar job the
Brett in MN did, but he made his opening 3.7". I measured
mine and they can be opened to 3.95". They also milled
the rim guides back for controlling case feeding on longer
cases. Ed

Re: 12GA From Hell

25/11/08 04:36 PM
Re: 12GA From Hell

The Savage has three front locking lugs and if action was
built thicker you could go BMG pressures.Pics of bolt
are earlier in the thread.
Here is information and reason for keeping and milling
the rim guides back for controlling case feeding on longer
cases.Rim guides are angled in from the sides of the opening
toward back. As the bolt pushes top case in the mag forward the
back of case and rim comes to where the tapers widen out so
the case then slides up in front of the bolt.I'm fixing up my
2nd Savage I have set up for my second 700H 3.25" belted case.
Just to see how it will work and along with other guys
doing it, get the info out to people.
This work on the stock/action can be done in a vertical
mill or good drill press. To use 3.5" plastic the opening on
the action and magazine needs 3.25", for 2.875"" brass long loaded
3.5", if 3.5" brass about 3.7", if 3.5" brass long loaded, 3.95".
By long loaded I mean a slug like the Dixie 600gr that protrudes
up to .4".The 730 gr flat wide nose slug protrudes 1/8".
You also have to widen and smooth the ramp going into the
front bridge so case lifts smoothly on the way into chamber.Ed

Re: 12GA From Hell

We get asked about putting brakes on the NEF Ultra.
There is the concept called the internal brake that works
nearly as good as expansion brake, with less back noise.
Rob on AR did a couple with bunch of holes in the barrel
in the end with the last 1.5" bored out .025" where holes
go. Also many want more velocity in NEf and I added on
a barrel section to mine. Combining Ideas we add smooth
9" section of bore extension, that is same as groove diameter
and 1.5" end of that for internal brake. Eight 1/8" holes
top and same 45 degees to each side.And we have over
a 100 fps in velocity gain. And with card or wad behind load
it will seal pressure going from rifled section to smooth.
And these types of holes won't bother wads or sabots.
My extension is a foot longer and gets 150 fps extra.
No need for brake in mine as the gun is 17 lbs with extra bbl.
Here is Rob's two he fixed up, and is shooting.He has
them reamed out longer for long 3.85" case, weight added.Ed

Re: 12GA From Hell

Here is a picture of porting holes in a 10ga NEF
heavy long smooth barrel. Bbl 30" and 1.080" muzzle
diameter behind the screw in choke area. This come
with slightly extended screw in choke and is first
10ga with long barrel as heavy as my NEF 12ga FH
short barrel was.. OR the short NEF 10 gauges
with heavy barrel..It came with full and mod chokes.
The other 10ga I tested earlier, only .960" at muzzle.
I cut choke off and put it back in leaving the barrel
an open bore for slugs and leaving an area 1.2" long
for an internal brake to drill all the holes in like
Rob did with NEFs in his picture. Now the 1.2" long
area where holes are is bigger than needed for 10 ga
so a reamer in the making will solve that and solve a
major big bore project for me and others who asked
me about using the short NEF 10ga for upgrade, which
I didn't encourage putting all that work on a short
barrel gun, with the amounts of powder that will be
burnt in....are you ready.......THE 8GA FH.......

More info on the heavy barreled gun we plan on
making 8 gauge from. Nef SB2 103, 30" barrel,
regular stock. 220 bucks. 100 bucks for shop to
ream out to 8 ga smoothbore. Needs the 80 dollar
thumbhole stock. Nice deal for a modern 8ga, using
heavy duty plastic 3.3" long cases. I fired 6-8000
ft lb loads in one I made on Enfield, 4 times reloaded
without resizing cases.
Here is other project suggested by Boomie

Cases made by me from bmg brass. Took 5 swagings, and
two turnings on my case spinner lathe.Two Annealings
Got couple cases made, in picture our 3.5" case and factory

A while back I got tired of short barrel and
added a foot on to it. Used breech end of left over
Savage and a sleeve. Lined up rifling and it has
same twist and number of rifling. Hard way to do
it. No need for rifling, or extra line up work.
Run many loads and it adds 150 fps with VV110,
4759, and 4227 powders. Adds about a 100 with
Blue Dot, and HS 7.

Next one will be done different and easier.
Next one will be a smoothbore add on piece of
groove diameter, 10-12 inches long, make it one
piece, 1 or 1 1/16" threads,about 1.2" diameter.
Threaded 1.5" long on original barrel, and into
add on piece, and will look like a brake and you
could put in internal brake in the end.Ed

can headspace a BMG rimless case,no belt, so you could
put on a 12ga barrel, straighten case more, from .700 to .729"
and have the rimless 12ga. Could straighten case for a
.750" bore, even to 10ga(.775") with a little thinning of the
top one inch of the case. Experimenting is interesting
to say the least. 700 slugs in pic are 1000gr Woodleigh,

Re: 12GA From Hell

Before I posted about testing a NEF in 10ga with
a medium heavy barrel. The newer one is better.
It is the one I showed the ported barrel previously.
I did some 10ga FH testing in that newer, real
heavy barreled, NEF 10ga, that is going to soon be an
8GA FH, after reaming out. The internal brake set up
on the end as shown in picture above works great.
I stopped all of the muzzle rise and cut recoil
Gun now is 14 lbs and has thumbhole stock.

Re: 12GA From Hell

28GA FH new slug.. The Lyman cast 20ga slug made to
fit in a 20ga shotcup for 20 ga slug hunters, works perfect
in the 28GA FH brass case. It is a hollowbases hourglass
shaped 362 gr slug. No wadcups or wads needed, loaded
right on powder. It is the slug you buy the molds to cast
your own or you can buy them from guys who cast for
sale. I use slow rifle powders in case so no air space,
they fill to the slugs. I got 2900 with moderate case
expansion and it hits target straight on, from a smooth
28ga heavy barrel on 695 Mossberg bolt action.

Other new info on primers. Some of the guns can't have the
firing pins or hammers beefed up easy like my Enfields
With some magnum primers with hard cups you get delayed
ignition if hammer doesn't have perfect hit and high strength.
One test with a small diameter case/bore that any primer will
ignite slow powders fine with good firing pin spring would
show delayed ignition with shotgun battery cup style 209
CCI Mag and 209 Federal Mag primers, and when I tested them
in cases with just the primers, they only put in a small dent
when they fired, but WIN 209, REM 209, RWS 209(used in
Brenekkes, Lightfields, Hastings), dented in much more when
firing just the primer. And with the smaller bore you had fire out
the end of the barrel, so you could compare primer strength
visually. The REM 209 was as good or better than CCI and FED
209 Mag Primers. The WIN and RWS was close behind. We put
the REM in same case/gun where that we had delayed ignition
and it fired instantly, no delay. The two mag primer brands have
the primer insert in cup rounded a lot and little harder metal,
and the other 3 metal cup insert is almost flat and slightly
softer. It is easier to get a better more solid strike and dent.
I always figured mag primers were best in our hopped
up shotgun loads but not anymore. It took a while but I finally got
everything around for proper test. Hopped up loads(regular also)
we have talked about, use REM 209, where the firing pins
and hammers can't be strengthened. Even loads with Longshot,
Blue Dot, Steel, HS6-7, etc.
Hope this helps.....ED

Re: 12GA From Hell

Here is picture my NEF, soon to be, 8ga gun.
It weighs 15 lbs. The hollow butt and hollows
in the forearm are weighted. It has a neat recoil
barrel ring I added so forearm stays put.
It has internal brake on barrel that I picture
earlier in thread with the porting holes.
Second picture is a Lyman 520 gr slug on the right
that we are testing . They go in regular 12ga shotcups,
and many folks have good accuracy with them, even
in smooth bores. They are hollowbase nose-heavy
design. These are the ones you cast your own.
And there are guys casting some for sale.
You see two in wadcups on the right.
On the left is my prototype of the Lyman
style, of 900gr for our 8GA FH. Going to get a
mold made. The base of it will fit the 8ga shotcup
used in the kiln gun loads, and the front will be our
smoothbore 8ga size, .832-835". I designed this
as the flat ended kiln slug without a hollow
base and heavy in the front, wasn't designed
to give 100yd accuracy in a smoothbore. Ed

Re: 12GA From Hell

Good looking slug, Ed. I wonder how many 5 gallon pails of water it will penetrate. That's pretty light for an 8, isn't it? should be able to get it really trucking. I would think you might want to try WW hardened. 460F or thereabouts for 1 hour then quenched in a bucket of tap water - something soft on the bottom, let sit for 12 hours or more & they should come up to brinel 30 approx. I Suspect you've done this before.

Re: 12GA From Hell

Daryl,
I have shot the lighter 20 gauge slugs,(350 grains) through three, one gallon water filled milk jugs and into the fourth one, which split and released the slug, which rolled off the table and onto the ground. It had expanded to the diameter of a U.S quarter and is the only one of these slugs I ever managed to retreave intact. Bob H.

Re: 12GA From Hell

Thanks for chiming in here, Birdhunter - Were they pure lead or cast from WW metal? The expanded bullet pictured looks to be harder than pure, but softer than 12 or 13 brinel, which is what I get with our WW's. At that diameter, I'd expect more cracks - and not as large an expansion.

Re: 12GA From Hell

The slugs I got are 30 to 1 lead/tin mix and seem harder than
WW slugs. As for the 8ga I may make nose little heavier,
but those proportions are like the 12ga one, which most folks
says shoot easy and fast and accurate. So I want same for 8ga,
without going over pressure in the barrel we are redoing.

RIP on AR forums been testing starter powders loads, with
shotgun primers,with Blue Dot starter and HBMG main load. And
I just tested some variety of ones myself.
Doing some testing with starter powder, 15gr Blue Dot, with
slower powders that fill the cases with minimum wads.
Tested in 3.5" RMC case in NEF with shotgun primer,
with 36" added to barrel.Remember I have extra foot of bbl.

These 4 top loads expanded case, where I check it, just above
thick base section to .811" from .807" resized.

1000gr jacketed, 230gr HBMG, 1800 fps, 7200 ft lbs,
with 1/8" cards and 1/4" felt wad.

715gr jkt, 270gr HBMG, 2200, 7600 ft lbs, 1/8" card.

600gr Dixie, 250 gr Retumbo, 2400, 7600 ft lbs, 1/8" card.

385gr jkt AL core, 250 gr RL25,2900, 7200 ft lbs.
This is faster than lighter loads in NEF, using 4227 powder.

Now the starter powder loads, which a few guys like, increase
powder speeds so that HBMG acts like RL25. In first example,
with 1000 gr in RMC case you couldn't use 230gr of RL25
as that would expand RMC brass too much and stick the case.
A few guys have found that slow powder, with starter
powder is easiest for 1000gr and heavier loads.

On another note, I've heard around the grapevine that if
enough of us ask for NEF to make available a 12ga Ultra with
a 28" rifled bull barrel that they would do it.Start calling
folks, maybe do some good. Just tell them these new sabot
and fullbore slug loads need more barrel to get the velocity
out of them. 1-866-776-9292. Ed

Brass 3.25" cases from Rocky Mtn Cartridge. It
will work in NEF/H&R 28ga modern break action guns
that cost 150 bucks, 26" barrel, you lengthen chamber
for the brass case. Good hunting loads would

good defense load. Two Brenekkes doubled up in RMC
case in the NEF. 85 gr of 4227 pushing 2 one
ounce KO slugs about 1600. Bottom slug has seal.

Also found a way to adapt extra slugs to 10ga. A
515 gr Lyman slug for use in 12ga wadcup, in my
10ga, using thickwall 10ga BPI steel no slit wadcup
shortened and Lyman bottomed out in it, so it
is like a discard on impact sabot slug. Like Lightfield
and Hastings. I shaved the bottom diameter of Lyman
so it would fit tight. Similar deal for 16ga using BPI 16ga
no slit heavy shot cup and 20ga Lyman. Now we have it
so that 2 Lymans can fit 10,12,16,20,28 ga....Ed

Re: 12GA From Hell

Good pictures as usual, Ed.

I am at a loss to understand why anyone would restrict & reduce the power of a gun by shootng an undersized projectile. Now, shooting sabots from a 120mm cannon, I see that and it certainly has merit. To reduce a wonderful .73 cal. rifle to a .50 or .54, well, I just don't understand the logic - unless it's just an execise in testing 'something' - that I understand.

Re: 12GA From Hell

Daryl,
Among others, one of the reasons to use a sabot is to reduce friction (pressure) between slug and barrel, especially when using other than soft lead slugs. Another reason is to "adjust" free space between slug and barrel, since bore diameter of shotgun barrels vary quite a lot, especially smoothbore ones.
In the brass slugs we make, sabot is mandatory and less friction results in higher velocity, as well.

Re: 12GA From Hell

Oh, I understand with solid projectiles, reducing the diameter slightly to allow some sort of barrier - I just don't see using grossly undersized bullets in a large bore and thus reducing power.

The Lyman sabot moulded slug is a good idea - the 'slug' is only reduced to about .68 cal. from .73, but to grossly reduce the diameter to the .50's is to lose a great deal of killing and stopping power.

Re: 12GA From Hell

Lot of deer hunting guys want less recoil and more speed with
a flatter trajectory that speed and
a slimmer more streamlined 50 cal slug in
12ga sabot can give them. And a 4-500 gr 50cal
slug at 2000 plus fps will do credible job.

Some 8ga experimenting and info. The 8ga chambers
I have are set up to fire the regular 8ga
size cases, and also REM kiln cases with bases
turned smaller, where the extra short basecup
is formed over the inside cup.Just reduce to the
diameter that it chambers ok and regular case
doesn't expand very much fired in same chamber.
This idea came from UK 8ga hunters that found
it was easier to get kiln cases. Now the other
case in 8ga available is the WIN kiln case and
ones I've seen are only single thickness basecup,
but they have the step formed in them to match
the kiln case belt size. Now you can't turn them
down any to fit my chamber, BUT you can swage
them down .012" in a die with a lttle lube on the
basecup. Examining them they do expand much more
than the doubled up REMs.I fired REMs 4-5 times
with bases expanding .002", the WIN I did
expanded .005" in one shot. I will use
heavier built REMs as they are 70cents
primed and good for 4-5 shots,
no resizing, with hairy 8,000 ft lb loads.Ed

Yes - I am aware of what they are doing - I just don't understand - well, never mind -
A 400 to 500 gr. .50 cal slug should have a 24" twist or perhaps a bit faster, but not needed. Apparently, PacNor makes a 22" twist 12 bore barrel. I wanted an 80-85" twist with 5-6 thou rifling, but am having difficulty finding one.

Re: 12GA From Hell

My pacnor barrels are 1 to 20-24, but up to about 440gr for me
in sabot they seem to stabilize in NEF with 1 to 35".
Speed is the difference as RPMs are faster so they
are still stable. I'm sure they'd wobble if I shot them
at only 1200 or so. As far as the real slow twist barrels
look up the guys specializing in black powder guns,
and also check with Dixie Gunworks.

I glued up 3 of 12ga prototype sabots. At 25yds( the 50yd range
is in the water and snow) And the three with 437gr .512"
slugs I did one 2" group with peep sights and bad eyes.
Running about 2400 fps from RMC case in the NEF 12GA FH
Shot 3 of my 28ga FH with Lyman 360gr at 2100, from
the Enfield 28GA FH, and got same size group.Real windy
when testing . Going cold and ready to snow again.

2" of wood between them. Made big hole.Ed

Those slugs are as hard as full jacket bullets and at
real high speed, and plates were mild steel.
Before it got cold again got little more testing done.
I shot 8ga Lyman 900gr wasp-style slug out of
the Enfield at 2350. I made it from heat treated
lead REM kiln gun slugs, and it went through 6 foot
of hardwood slabs in my backstop. Hit target square,
behind chrono, which is great from smoothbore.
It is hollowbase and seems very stable.And real hard.
I shot 3 shot group, with 12ga 525gr Lyman, in 87
smoothbore long barrel levergun, At 25 yards they
all made hole like cloverleaf. Used 3.5" RMC brass, with
Lyman in a WW12-114 shotcup, going 2100.Now my
87 smooth barrel is .722" at muzzle, .726" at breech,
so it gives tight support to shotcup and Lyman slug,
for fairly accurate load.....Ed

I haven't the resources to do one.

The Vias brake bored out in above picture will help
RIP with recoil as he wants to shoot all heavy slugs
in the NEF Ultra. Guys like the Vias brakes.They
can be bored out and fitted to anything.
I just like ported internal brakes and more gun weight.

Here are some results( had 1 nice day) with 8 gauge and
10ga light slug loads of my testing. I call them my real
big bore varmint loads. A 770 gr slug in 8ga fired in
Enfield at 2400 all 3 shots nearly touching at 20 yds.
A 515 gr Lyman, NEF 10ga at 2400, same tight group
at 20yds. Lyman is originally for 12ga, but is fit in
10ga thickwall BPI shotcup cut off and slug glued in so
it is like a impact discarding sabot. Both smoothbores.

Smaller varmint load. NEF rifled 12ga with RG's 385gr
aluminum cored jacketed HP slug at 2700, 2 overlapping
and one half inch away using RMC 3.5" case. Ed

Re: 12GA From Hell

Good shooting - the real test is 50 to 60 yards. With well balanced loads, smoothbore will stack them at 25 yards, just as will smoothbored long-guns, like the fusils and single barreled fowlers both with round balls and black powder. Something happens past 25 yards, but tends are good.

Most well bored guns, modern, that is, will hold onto 3 1/2" to 5" at 50 and that's good accuracy. I've heard of more 12's printing closer to 3 1/2" than not. I think that's one heck of a good bullet - cast hard and possibly quenched out of the mould (careful) or hardened with the hot oven and water quench method.

The three slug loads tested above are real

light for the bore size. Here is picture of
the 3 slugs for comparison. 1st is 770gr in 8ga wadcup,
second is 515 Lyman in 10ga wadcup, third is the
12ga 385gr HP with aluminum core. The 8ga wadcup
loses its petals going out the barrel, but
hollowbase 770gr slug stays straight.The 515gr Lyman
in the 10ga thickwall wadcup is also as a unit
nose heavy and runs straight. The Lyman is held in
cup with little plastic mender glue, so that it
acts like a Hammerhead and Lightfield slugs.Ed

Re: 12GA From Hell

Ed - the 10 bore load looks like a steel shot wad =- perhaps needed to get the thickness to fit the slug. Have you tried them in a regular shot wad? Paper patching (masking tape) might bring up the diameter to fit the cup well.

I used masking tape for patching in my brothers' .45 3 1/4" Sharps with very much undersized bullet and it shot well indeed.

Re: 12GA From Hell

Daryl- yes it is a 10ga steel shot wad with the Lyman
slug in it. A 12ga thin wadcup with same slug fits 12ga
which is what most guys use that Lyman for. The 10ga
thick steel cups are only a dime so it is easier than
trying to increase diameter of thin cups.In this way
we can use same slug for 12 and 10 ga.
Here is what a 600gr super hardened Dixie slug
at 29-3000 plus does to two mild steel plates with
2" wood between them. Fired from our long case
in the Savage.Two plates are soft mild steel.

Rifling buttons or a cutter that big, I can't find reasonable.
I was thinking of screwing a rifled choke in the stepped up area
on the end that I now use as internal brake expansion area, with
the ports..But I like the ports and the hollowbase slugs should be
75yd accurate based on preliminary tests with them. And the Lyman style
slug that I will get mold done for, will be better yet.

Re: 12GA From Hell

Fellas say they do ok.Most brag about accuracy.
I found a shotgun primer that will ignite rifle powders,
like RL15-19, IMR 4064,4198, etc. With regular shotgun
primers I had to use Blue Dot starter.
But not with these.....They are the industrial
shotgun primers used in the 8ga kiln gun cases. I use
these cases with basecup reduced in my 8 gauges.
When I set up first 8ga I fired the primers only to test
firing function(cases came with primer), then I put
regular 209 primers in to test loads, with 4759 powder.
Found box of WIN paper case kiln 3oz loads and took one
apart and noticed it had 94gr of some ball powder.
I wondered what powder is and how a regular shotgun primer
could ignite that, based on our need for starter powder
using regular rifle powders. So I fired that industrial
primer and flame and sparks came out of 8ga NEF barrel
2-3 feet. Put a regular primer in same case and flame
just a few inches. So I took REM kiln case with original
REM industrial primer and 2-3 feet of flame,and put regular
primer in and just few inches of flame. If anyone got
info on th powder used and how to get these primers,
let us know. I took some out of 8ga and put in 12ga plastic.
Using these hairy industrial primers today fired 180gr
of RL-15, in 12GA FH NEF, in 3.5" plastic cases with
437gr Brenekke KO slug. Got perfect ignition, no starter.
140gr with 600gr dixie, perfect ignition.

in, on Gunbroker, in shotgun singleshot section.Ed

Re: 12GA From Hell

I always felt that if some company would make powders like 7383
available it would be great. 7383 ignites fine with regular
shotgun primers in 12ga, but it is surplus and only a few of
us have it.It is a powder that has a lot of the deterrent inside
the of the material, not all near the outside like 99% of
all other powders whether spherical, tubular, or flake.
This allows easier ignition, but yet the deterrent still can
control the speed. Well the new RE-17 just out for 2 days
is setup like that. The surface of the RE-17 grains is
more porous than RE15, so that fact allows better ignition
even though a slower powder, and along with fact that company
got most deterent inside it still regulates speed.
Today I fired with regular REM and WIN primers in
plastic and RMC cases, a whole bunch of loads of RE-17,
with no hesitation or squibs or misfires. Loads ranged from
437 gr slugs to 750gr slugs today. All loads burnt clean
and I got in RMC case one of RG's 715gr jkt slugs to 2300
with 160 gr of RE-17. Using plastic you must have a strong
roll crimp with slug and wads tight.....Whoopee....Ed

Re: 12GA From Hell

Hmmm - reloader #17, eh - probably see that here in a few years. Guess I'm stuck with H4227 and shotgun powders.

What are you guys paying for those M110 Savages? Here, they're listed around $495.00 - bit much for an action - but not much else in a repeater around that will handle those long cases.

Re: 12GA From Hell

I shot couple loads with regular primer with RE-17
and 1040 gr slug in 12GA FH NEF, and it does great.
Tested loads that were cooled outside a while.Perfect ignition.
I fired loads RE-17 8ga plastic,in my 8GA FH on new NEF long
heavy barrel that was a 10 ga and RE-17 is great. No hesitation,
it fires off as good in 8ga as the 4759. Remember
I couldn't get good ignition in 8g with 4227, but so far
RE-17 is magic. In 8 ga all it would hold under the 8ga REM
wadcup with 770 gr slug is 200 gr of RE-!7, with the
wadcup pressed down, compressed real hard,good crimp,
and it really bellers.2400 plus.Going by case
expansion about 20k pressure. Which don't bother
those one piece compression molded super strong
8ga REM cases. You must have real tight proper
roll crimp in plastic cases and good tight
taper crimp or rolled in crimp in groove
in the brass cases. In RMC brass I size it so slugs
have to be shoved in with press.

And this RE-17 doesn't break up the kernels when powder
gets to a certain point, like the 7383 does, causing burning
rate to speed up more than what it was designed for.
I tested 7383 in my 700HE, and when up to 35-40k it's
pressure went up fast, much more than linear progression.
I still like 7383 at shotgun pressures, but I really like
RE-17.Just pour case full and shoot with lighter slugs.

Ok- for those who want to get into the 12GA FH and get
the long strong 3.85 inch cases Rob on AR got some made,
email him to deal to get some- garnickrob@aol.com
He can also tell you where to get reamer.Ed.

Re: 12GA From Hell

One of our testers, Bret in MN, got the BPI Sabot with
500gr Hornady .500 slug up to the good speed listed
on BPI"s loading sheet, using shotgun powders. I could
get them there with my loads using much larger amounts
of rifle powders. He tested 3.5" Federal plastic cases in
his Savage 210 with 3.5" chamber and the 28" heavy barrel
he put on. With 50gr of Longshot(max load for all modern
guns) he got 2550 fps, with 500gr in sabot. He use two
BPGS gas seals fitted together over the powder, then
a FS12 Flexseal wad, then a 1/4" cork wad, then the sabot.

Then a good strong roll crimp with drill/drillpress crimper.
This load is at mag shotgun pressures by case expansion
measurements and BPI's 46gr load tested at 12,500 psi.
He also did one with one BPGS and two Flexseals and had
200 fps less.He had tried other combinations seals/wads
and with same amount of powder and got lower yet.
He also went up with the powder, with seal/wads that worked
the best and got about 3000 fps, but the plastic cases
stuck and wouldn't eject easy. I will be testing same
seal and wad column in a few days, in my NEF with long
barrel to compare results.I thank Bret, he is a real
good experimenter and idea man. Everybody is trying
like crazy to get that 500gr saboted slug up to big
game gun velocities with shotgun powder and thanks to
BPI"s supply of the right components it has happened.Ed

Re: 12GA From Hell

Rob on AR is building a 12GA FH double on a Zabala Double
10 gauge frame. It has the Greener crossbolt. He cut off
barrels to make a 4" long monoblock double to screw a
pair of heavy 12ga rifled Pacnor barrels into. He reamed out
monoblock section and threaded it. His barrels are
1.116" at the breach, .97" at muzzle and 22" total length.
Barrels threaded into monoblock with a 15/16" x 32 thread.
In the pics it is partly done and he will put in the ribs
and integral sight rib and regulate for accuracy.
It will be about 14.5 lbs when done he says.Ed

Re: 12GA From Hell

I suspect that 500gr. is being punched out of a 22" or faster twist?

That is power - 2,550fps with 500gr.! OWWW and WOW - and from a rifled shotgun! If of standard 35" ro 36" twist, I'd be staying with something lighter than 360gr. and probably attempt to get an accurate load with the 300gr. Nosler - that should work about the best wouldn't it?

Looks like I'm going to have to come up with a box of 3.5" plastic and break them down to do some testing. My torn shoulder is hurting already.

Re: 12GA From Hell

His savage is 1 to 22 twist I think, but BPI tested
500gr in sabot in guns with 1 to 35 and 1 to 28 twist, and got
good accuracy with no signs of tumbling.Of course it
is the bullet rpms, so faster bullet needs less twist.
The point of Bret's and my testing is to find best seals.And
this seal and wad combo we found is much better, than
cards and wads or other plastic seals. And they cost
no more than others, and the sabots are reasonable too. Ed


hubel458
(.375 member)
20/04/09 06:10 PM
Re: 12GA From Hell

Some more BPI seal and sabot testing.
First of all both Bret and I have heavy tight fit barrels
and his barrel on the Savage is faster twist so it took
him 50 gr of Longshot to get what BPI got with
looser barrels and slow twist at 46 gr of Longshot.
For non heavy barreled guns only go to 46 gr.
I did a bunch of tests in my NEF long barrel with long
chamber. My store didn't have any 500gr .500" XTP slugs
so I used some 420gr .512" dia lead Great plains in the
BPI sabot. Using 2 BPGS powder seals, a BPI Flexseal, a
cork wad in 3.5" new Federal cases, roll crimped, I got
2800 fps with 420gr slug. I tried 4 other powder seals,
2 cards, a Remington, a Win, and a odd one, all with the
Flexseal and lost velocity. I fixed up my crimper so it would
roll the plastic down and over inside edge of sabot, as before
it would turn plastiC in too sharp and get some of the crimp
outside the sabot top. If sabot was too low so that the plastic
crimp went clear down to the slug I got high pressure signs.
I also did same loads in used 3.5" REM cases ok.
Now, I thought I should have more velocity, so I swaged the
.512" 420GR slug down to .500" like they say the sabot is for,
AND I GOT OVER A 120 FPS MORE. Everytime. I also used
Alliant Steel powder and got all the same results, using
60gr. It is easier on cases. I also substituted the doubled up
BPGS powder seals and the Flexseal with 520gr Lyman in
place of the seal and cushion on the WW12 wadcup the Lyman
fits in, with some RL-17 loads, of 150gr, and got over 200fps more
that the original WW12 wadcup gave with the Lyman.

Velocity secret is to have the perfect sealing setup with
slug/sabot combo that is NOT too tight. Only tight enough
to get accuracy. The cork seems to protect the sabot
base ok on the shotgun powder loads, and not needed
on the RL-17 loads, which is a easier accelerating powder
and without cork helps make room for the RE-17. I think I
will get increases in the brass RMC cases, with RE-17, with
the BPGS doubled and a Flexseal in place of cards and wads.
We will know soon.Ed

Re: 12GA From Hell

It is heavy enough. It is .145" thickness at chamber.
I've fired factory kiln loads with 1000gr slugs fine.
The SB2 NEF is built strong. And the kiiln gun plastic
cases are as strong as most brass cases, so they take
part of the strain also...
Here is picture of a 12ga size drawn brass case that was
made back in the 80s. Case is for the CAWS weapon system.
Case is belted, and it and the gun operated at 25,000 psi.
Its bore size is between 12 and 10 ga size, but the od of
the drawn case would let it start in 12ga chambers, so
they added belt so it couldn't go all the way in
to regular shotguns. Notice the thick sides and corner
near the base.Heavy enough for 25,000 psi. They loaded
it with big buckshot and test other projectiles also.
They had a plastic card over shot and filler and rolled
over brass mouth for crimp. Ed

Hmm - belted 11 bore - Parker made quite a number of normal 11 bore doubles - of course, ammo is no longer available for them.

Interesting case, Ed. Yes - quite heavy and suitable for pressures above 25,000 - in a gun that is also safe for those pressures.

Re: 12GA From Hell

Here is picture of a NEF breach barrel section that I threaded
monoblock style for a .585" cal barrel, to make a NEF 585HE.
It goes on a SB2 10-12ga alloy, super strong frame. Its
OD is 1.210" and the barrel that screws into it will be tapered
to match contour and it will be 1.00" at muzzle, at 32" long.
I know these are strong enough as my 8GA FH testing shows..
Later will do couple more with heavy barrels for 28GA FH, etc,
as all the break action 28 gauges I've looked at have too
thin of muzzles for our slower, powder loads.I'll have 3 of these
that fit one SB2 frame I have here.This makes switch barrels

I fired mono-blocked NEF this week with a 585HE 32"
barrel and the gun is weighted to 15 lbs. Thick pad.
I have cone breech as this case is belted with thick base.
I'll have a pic of gun later. Gun is still tight after testing.
I can take out cases with my fingers as they don't stick.
First 650gr, with no extractor. The HBMG, WC-860,AA8700,
Retumbo, Magpro, RE25, W-780 loads come out of the chamber,
with my fingers.If I tip gun up they fall out.
Top speed with RE25 and W-780 is over 2400. Now I knew what
to load them at because I have tested this case in 3 other guns.
I have all the different powders and bullets tested.

Here is the finished NEF mono-blocked gun with
the 585 barrel, 32" long, 1 to 22 twist.
Chambered for my 585HE belted case.
I used a SB2 10ga action which is same as the 12ga
Ultra actions.I cut it off to make a 4" long monoblock.
and threaded it 1 inch by 14tpi. I'm going to do extra
ones 28GA FH,others.. My 585 is best 585,as the info will
show. I have a 45-70 extractor coming to rework for it.
I am firing first bunchs of test loads without
an extractor, and loads with 650 gr bullets at 2450 and
750 gr bullets at 2250 didn't need the extractor. They
come out with my fingers. Over 8000 ft lbs.I got thumbhole
stock now, because those with higher velocities of 2-400fps more,
were harder to hold on to grip. Trigger guard banged the fingers.
And higher velocity cases come out with a pry from my thumbnail.
Here is picture of rear of gun and the fixins(bullets/cases).
You see a fired case in the chamber, and I have cone breach
setup so that case is in same relationship to chamber as it
is in my three 585HE bolt guns. And is why I can get cases
out with my fingers.OR tip gun up. The hairier loads of
650 at 2650, 750 at 2450 is 10,000 ft lbs. Ed

Cast bullets with lead and antimony and with a touch of arsnic, are heat treatable to brinel 35 - max. I seem to remember that dead soft copper is brinel 40. Pure lead is brinel 5, WW run at about 9 to 13 depending on who made them, while Linotype is brinel 22 & brittle. Foundry type is brinel 28.
Ordinary lead/antimony WW can be heat treatable to brinel 34/35 & will penetrate animals just like a non-deforming FMJ RN or FN. Some jacketed ones aren't as good as the lead variety in penetration.

Speed allows penetration all out of proportion to the materials used. A .224", 48gr. soft varmint bullet going through 1/2" of armour plate, yet an issue FMJ '06 made .008" deep pock mark and a .270 130gr. nothing more than a lead splash on the same plate.

May change/lengthen fulcrum on lever so it doesn't have to
move so far. Lever is held closed by little feramic magnet

block. Block moves smooth, no rattling around.

The NEF handles pressures fine, just doesn't extract
like a bolt action Savage 210. Using RE17 without cork,

In related big bore work we got a Montana Rifle

test load of 825gr at 3000 fps. This was just one
test load. Normal max loads are 825gr at 2850 and
1000gr at 2700.Hunting loads 24-2500, First PH fired
outside the factory.It is in first picture.
PH will work for any big case and my 585HE.And
if anyone looking at big actions for 12ga FH,
here is picture of MRC PH with a 3.5" 12ga case
partly into action. The PH cam be used for 12ga with
action and rails opened like I did my 700H in Enfield.
And a little changing on the bolt face and extractor
In 12 ga it still would have 60% of front lugs contacting
and you'd add bearing lug surface to bolt handle base so
it would handle same pressures as Savage 210.
And 3.5" with average length 12ga slug would feed from the

inside the PH mag box. Easy to fit in metal box,
and permanently mounted to metal and floorplate.
Holds 2 down. That way feed lips already a working
design. And opened back of 12ga box for longer case
like I did with my 700 in Savage 210. Also work
for anyone doing a PH in 12ga FH if they aren't
loaded too long or with 3.5" RMC cases. Using most
cast 12ga bullets like Dixies, the overall length with
3.5 brass is 3.9" and fits 4.05" box ok. Here is picture
PH from bottom showing its big size.You can see in pic
there still is room to make box longer yet.
And the feed port can be longer.Montana Rifle has
great action here with lots off room and strength.Ed

I got barrel on the 4ga/bore falling block gun.
Barrel 32" long, 1.87" breech, gun is 27 lbs.
Notice breech block is down and huge hole in barrel.
Maybe shoulder cannon is the right term for it.
It is all inleted into thumbhole laminated Vulcan
50 cal stock, of which I need more, if anyone
knows where there are any. 4 bore cases shown,
and I'll use a big ammomaster press for them..Ed

Buck and ball loads are tremendous close-in from such a find 'big bore'. I'd think a good sized handful of 000buck on top of a 4 bore ball should do the trick just fine.

Re: 12GA From Hell

got 3" chambered 12ga set up to test loads with RE-17.
Many guys want loads for 3" chambered slug barrels as they
come from the factory., So I put extra 24" Savage barrel I had
on a Mauser GEHA bolt action. Rifled Savage barrel is modern
steel with .93" muzzle diameter. Original barrel on the GEHA
was only .82" at muzzle. I added an extra rear bolt locking lug
onto the Mauser bolt. Using up stuff to make test gun.

Any modern steel slug barrel, whether on bolt, autoloading,
pump, or break action gun with same muzzle diameter will handle
these RE-17 loads. Max loads were all 115gr of RE-17 in plastic
3" cases, all with seals and cushion wads. Can't get no more under
the seals, cushions and slugs in 3". Which is why I like 3.5"
chambers. With 437 gr Brenekkee and 420 gr in BPI sabot got
over 1900. With 520gr Lyman in shot cup 1850. With 600gr Dixie
got 1800. With 870 gr hard lead got 1600. This is 24" barrel,
so longer barrels will get more. In comparison to IMR4227 loads,
these are about the same speed as using 90gr of 4227. But this
powder is so much easier on cases and guns, with about .004"
less base cup expansion. It works great in 3" and really gets the
speed in 3.5" cases, as in 3.5" cases,as seal/wads about same,
extra length for powder. The 870gr load is max peak pressure of
16,000 psi. Muzzle pressure is about 3500-4000 psi.
I'll have pic of the Mauser in few days.ED

for my 499HE a real long brass case. Also I am
doing my 499HE in a NEF. You can get a NEF with
MMouse 500S&W and run my reamer in and get real

Re: 12GA From Hell

Here is picture of the Mauser GEHA shotgun I
setup with an Savage 210 rifled barrel. Used a Savage
plastic stock also. It is setup with the original 3"
chamber. I have many guys who want ideas and slug/load
combination's tested in regular rifled slug barrels, so
this is the one. Most testing will be 3" plastic cases.
Barrel 24" long, .93" regular slug size muzzle diameter.
The GEHA was originally converted from 98 Mausers in
Germany in the 20s, to 12ga by reaming outl the front lug seats
and using the rear safety lug. I added a second rear
bearing lug and it handles 15,000 psi loads ok.
The cases come out with the weight of the bolt.
That will be max pressure used in it, with that slug gun
barrel thickness. Example load is 115gr of RE17 in 3"
plastic case, with 520 gr Lyman cast slug at 1850 plus fps.
This load expands the plastic case base cups about .005",
in comparison, a REM factory Buckhammer and other super
mag turkey and goose loads expands .010".
And we have over 300 fps more velocity.Ed

Testing some .660" diameter 630 gr hard cast
slugs in the red WIN wadcup in 3.5" plastic
case. Tested in rifled long barrel in 12ga
NEF about 2100 fps. Greg Sappington makes
these. They are hollow point. 3" group at

a couple to see if they'd work in my long
brass cased 16GA FH shown in the picture.
They work ok, so Greg has a double duty
slug.They'd work in 16ga plastic also.

This is very important and most interesting, Ed - which, of course, you know.
Real world power at less than factory breech pressure - or longer, lower pressure curve - all good stuff for reasonably heavy barrels.
I havent' accuracy tested the Lyman slug yet in my rifled Mossy 835, but turned in some amazing accuracy using WW alloy round balls - stacking, on one top of the other at 30 yards, offhand - good speeds too, using 30gr. of SR4756 in 2 3/4" cases. So far, I haven't tested the 3" hulls I've prepared from 3 1/2" factory. I expect an easy 1,700fps with the 550gr. RB's. What terrific in-camp bear loads these will be, as well as straight hunting loads for bear and moose. More power than needed, of course, but exciting non-the-less. I'd not expect that hard ball to stay inside a bull moose out to 100 yards.

Re: 12GA From Hell

Mathew what chambers are you asking about. Most shotgun
smiths have reamers to deepen chambers. I have reamers
folks can use for my 585,700 wildcats.
Comparing brass cases.I tell everybody who are stepping
up in power from 3.5 plastic, you can get 3.5" brass cases
from Rocky Mtn Cartridge. Here you can see how heavy
and nice they are compared to regular brass cases.
They also make shorter 3" brass cases also.
They fit the chamber tight and are long enough to
get some serious thumping power.And they have a
super strong, thick , solid head, not a weak balloon head
like regular ones on the left in pic.Ed

Dave Kiff at PTG makes reamers I understand, for both

Tested my 499HE in a NEF. Loads I didn't have to
full length resize the case, only top 1/4 of case.
325gr at 2600, 500gr at 2150.
In NEF got both weight bullets 300 fps faster,
still extracted very easy.I got reamer. Just run it
in NEF 500 chamber and you got a blaster. And add
a little weight and thick pad to the gun.I have
a barrel ring to hold forearm along with original

Re: 12GA From Hell

You can do a lot of nice big bore ideas with NEF.
Just add weight. The 500 S&W I think is about 18"
twist and .500" groove diameter. Uses all the
.500" diameter bullets out there in bigger supply
than the .510" bullet other 50cal use.Something new.

Finally an 870 with longer 1" muzzle barrel. Barrel
is heavier than most all add on pump gun barrels,
and it is 25.5" long, Something that would really get
it on with the slower powder loads we have.
Rifled barrel is solid mount in receiver, scoperail solid mount.

It is the REM 870 Super Slug Gun.
Nice long heavy barrel, and thumbhole stock for
handling recoil better. Plastic case 3" slug loads of ours that
gets 600gr slugs to 1800-1900 fps, work great in this
Like the ones I load and roll crimp in second picture
that are setting behind the little vise, and the one in the

Re: 12GA From Hell

Been meaning to ask-Would the bolt action Marlin slug gun stand up to any of these loads? Haven't seen one in a while but I seem to remember it having a heavier barrel(maybe not heavy enough to use .50 brass as-is though). I noticed the Mossberg 395 mentioned a few times so I got curious about the Marlin.

hubel458
(.375 member)
03/10/09 04:43 PM
Re: 12GA From Hell

The Marlin would handle hotter loads than factory, but can't
be opened up in the port for real long cases. The Mossy 395,
495 and 695 can go to 3.5" brass cases, and looks nicer.
The loads I do with the RE17 could be used in Marlin 3 inch,
that I tested above in the Mauser with regular slug barrel.

Here is a novel slug idea, hard plastic support ring on
the front, and a locked base ring/seal. Metal never
touches the bores. Work in great rifled and good in
smooth barrels. These are steel, lead/copper would do
great also.Could be made heavier and different points.
Flat point shown would do great damage to game.
On the net- ammunitiontogo.com
This one is about 500 gr.

Second picture is the 499HE to use in redoing the 500S&W,
shown on the also, in single shots, etc,for those wanting
much more power at 40-50% lower pressures.Ed

Re: 12GA From Hell

So many guys want 12ga sabot type slugs to reload their own.
Here is an interesting combination slug available in Europe
and they are working to get distributors/stores here.
Any interested stores and shops contact them. We need
many sources of saboted slugs for reloading. The sabot
petals discards completely as slug exits muzzle and locked
on base stays with slug, making it nose heavy so it will give
decent accuracy in smooth bores.Will work in rifled barrels
also. Slug is .629" diameter, comes in 570gr, 700gr, 970gr
weights. They're selling these reloader/other loaders only.
It is called the US-S slug, and their site is
europeancartridgeunlimited.com ..Ed



hubel458
(.375 member)
21/10/09 08:01 PM
Re: 12GA From Hell

The company kindly gave me few US-S slugs to test at high speeds.
I had helped him test another slug a while back.
He sent me some each of the US-S 570 gr, 700 gr, 970 gr.
I tested the 570 gr so far and in 3.5" plastic case in the 1887
smoothbore 35" barrel and in the NEF rifled 36" barrel at
1900 fps. I got that with 130gr of RE17 with one BPGS
seal under the sabot on the slug. The bottom of the sabot seal
is exactly like a BPGS, so a BPGS added gives double sealing.
Both smooth and rifled gave 3 shot 3" group each at 50 yds with
peep sights and bad eyes. This slug does as good as advertized
in smooth barrels, and smooth accuracy is as good as rifled.
My smooth barrel is tight, measuring 723" at muzzle.
These should be a great deer and hog slug. Folks need to
ask their dealers to work to import these for them
to have what seems a good slug to reload...

On another note we may have found a guy who is gearing up
to make 10 ga rifled barrels. I'll know later this winter
If so I will put one on a bolt action and use the 4.1" long
10GA FH case I made or get some like it from RMC..Ed

Re: 12GA From Hell

Here is picture of the US-S slugs in a lineup
with other 12ga slugs I'm testing. Lefteris was
kind enough to send me a few of each weight
to test. They are the 3 in second row on the right.
They are 570gr, 700 gr, 970 gr. I tested 570gr in
3.5" plastic so far. At 1900 in the NEF rifled, and
in the 1887 smooth barrel, got 3" group on both.
With peep sights an bad eyes.So the US-S slug
is great in smoothbores, as good as rifled. My
smoothbore on the 1887 is .723" bore at muzzle,
a nice tight fit for smooth slugs. The smooth
bores Lefteris tested them with are .722" muzzle,
and they've already killed 5 wild boars, one shot
kills with the 570gr slug. Also if anyone wants a
heavy smoothbore new 12ga barrel, .722" muzzle,
1.375" outside diameter to make a great slug
gun with slugs like these, and others like the
Brenekkes, I have spare one. The US-S slugs
are smoothbore accurate in my 87 like the
Brenekke KOs.ED

than regular 12ga mags, but same setup would do for feeding
long brass 12GA FH and long MRC 12ga cases. The
700H 3.25 is 3.9 inches overall loaded length. In picture
case is ready to clear the mag lips, then rim pops up under

Our cartridge work and experimenting got a nice
write up in # 470 Nov/Dec International Ammunition
Journal. Page 10-11 by Zach Weighman, a
cartridge collector and gun nut friend.

Got a guy just figured out BMG case rim, and for a rim
puts on 12ga high base cup from a plastic case. He turns
base/rim of bmg case about .008" and use JB Kwik to hold
it on. Pushes it on with press. He removes base cup with
heat gun from plastic cases,

He is using RE17, so shotgun primers will work, and he
puts bushing in case for primer. Has bushing reamed so
the primer pocket protrusion on the base cup goes up inside
tight, as he pushes on the base cup. It'll fire ok and to size it
do like I do, I push case into open top die, and push it
back out from the top with a rod and hammer. That
way the rim don't get bent up. He says it saves a lot of
time not having to make rim pieces.

We will have more info and pictures next few weeks.Ed

Here is a picture of a BPI sabot with a BPI Flexseal I
use on to it in place of the original cushion seal.
I also cut shallow slots in the outside at the bottom
of the petals. Sabot opens much quicker and seems
along with BPGS seals under it to work ok without
damage, giving high velocities. In pic on left is regular
BPI sabot, behind is one I put a cushion on from a
Brenekke KO slug, and in front the one with Flexseal on.
The slug in it is one a guy casts at 440 gr and .504"
diameter, and works ok.

New info on my 499HE, from now on we will make cases
out of 450 #2 brass, as Jamisons has 3-4000 cases,
and it seems no one has the 475 #2 we used first.
Only slight case dimension change is the base .012"
smaller, all else is the same. I'm getting reamers redone
and will be able to use in couple weeks. Case will still have
plenty of taper to extract easy in singles, doubles,
falling blocks.etc.

And speaking of falling blocks I found one, and put my 585HE
in it, and it is big enough and has enough clearance to be used
for a 577NE, 600NE, long 20ga, my long 16ga FH,
the 700H, the 700HE. Cost no more than Ruger. Will have pics

Here is picture, Falling Block I found that I put
my 585HE in. It didn't need any work on the
feed trough to feed. 585 case shown in it.
In fact the trough is big enough
and the action big enough for 600NE, 3.5" 20ga
brass, 3.5" 16ga FH brass, my 700 HE long case.
I reworked a NEF stock to it, as I'm not
a stockmaker.Nice action.2nd picture is

Re: 12GA From Hell

Here is picture of the FBW falling block with my
700HE long case in it.This falling block is 1.5"
wide, with a 1.125" wide breach block.
The sides are .187" thick next to breach block.
This compares to about .165" say for a Browning
B-87, Win copy. The feed trough would work with
12ga size rim if some work was done on the top
of the hammer. This has a barrel thread length of
1.005", thread diameter of 1.125" for good
strength. Ed

Here is picture of the falling block with a
600NE in the feed trough. Work great
chambered as a 3.5" 20 gauge, for
20 gauge 3.5" brass and plastic cases also.

Second picture is a 12GA FH case we made by
epoxying on a 12 ga base cup onto a bmg brass
case. Turned brass down .010" and pressed on base
with epoxy in it and when set base is on good.Ed

Re: 12GA From Hell

Another way that I put a 12ga rim on
bmg case is to use the new Magtech brass
12ga cases made by CBC in Brazil.
BPI and others sell them for less than
a buck each. Being so short they aren't
in the 12ga FH category of generating power.
But you cut them off a quarter inch long, and
turn a BMG rim down to .715 diameter, push on the
Magtech base, with JB weld in the Magteck
base, and set up a squeeze collet to
crimp the Magtech base sides into the BMG
extractor groove. Crimp it in hard and tight.
And it uses large rifle primers.Fed Mag 215 best.
Other bmg case work needed is to put a chamfer
on the bmg primer pocket and drill out the
bmg primer pocket straight so that there is no
block to the primer gases coming out through the
Magtech flash hole. Chamfer back of rim a little.
These will handle
20,000 psi loads.Ed

Re: 12GA From Hell

I did a rough crimp job with magtech in a chuck
with a bolt cutter to squeeze a little at a time
going a around it.Not fast or neat, so to do it
right and even, you need a very strong squeeze collet
fixture with collet segments raised to just
push in on the edge you are crimping into
the groove.Ed

Re: 12GA From Hell

Yes a proper collet closer/crimper with needed strength
I can't afford either. So I am making them with base cups
epoxied on,as guys wanting them for their collections.
Anyone wanting one, 20 bucks shipping included, in the lower
48 by UPS. That is loaded and primed with jacketed slug.

Here is picture of Brett Ittel's Savage 210 he has setup.
It has a 3.5" 12ga chamber in a heavy 27" Pacnor barrel,
that he put in place of original. He also put in a Knoxx
spring/cam recoil absorbing butt plate in the hollow
Savage plastic stock. He replace the plastic parts of the
absorber with aluminum parts. It is shown without the boot
so you can see how it is in the butt.He also has an oversize
pad on it. He hasn't weighted the gun with anything else and
it shoots comfortable, even off the bench with loads that get
a 500gr slug in a BPI sabot over 3000 fps. He gets this speed
with BPI and 500 gr in 3.5" plastic cases. He also can use
3.5" RMC cases and our BMG based case, cut to 3.5"...Ed

Re: 12GA From Hell

Some 8ga work.I found a way and made a die that
swages the 8ga kiln cases down to regular 8ga size.
It swages the belt down and a turning tool I made
removes the sharp edge on the belt after swaging,
to make a smooth transition to the right size.
It does it 4 times faster than previous process.
My chamber on the NEF is set up so regular sizes fit
and loaded kiln cases with the belt step won't go in.
It works with both the REM 8ga cases from BPI and the
WIN 8ga cases from Precision Reloading, and the
WIN cases are only 44 bucks a hundred, primed.
The WIN cases have the same extra powerful primer
just like the REM cases. The REM cases are black
and the WIN cases a see through plastic. Both same
thick sides.Anyone needing cases worked over
contact me... Ed

Re: 12GA From Hell

The 8ga rim about .170" smaller than NEF barrel,
Important is that the base is about .280" smaller
so it has good strength.They use good steel in NEF.

It took a few tries, but I got a 8ga resizer working
perfect. And a tool I use on my case lathe smooths
the transition so cases don't hang up when extracting
even with heavy loads.With REM cases I fire about
four times without having to resize.

A switch barrel auto we are testing 3.5" 12ga
smoothbore USS-S slugs, with hopped up loads.
About as accurate as the other guns here. Also
I'm getting the auto set up in my 585 HE long
case.585 HE long case shown in the port.
Switching barrels only takes minutes. This 12ga
barrel about as heavy as the 210 Savage barrel.
It is originally a 3.5" 12ga autoloader I've reworked
the stroke and have a barrel extension coming to add
585 28" barrel. Gun is weighted, thick double pad.
We are going to see how mild 585 HE loads of
9,000 ft lbs work in autoloader.Ed

Re: 12GA From Hell

Guys have asked about a 10ga FH, and it is just
getting stuff to do cases with reasonable time and cost.
So a breakthrough with a 10ga FH, is putting 10 gauge
basecups from plastic cases onto 50cal Russian brass to
make a 4.05" long 10ga. I expand case using my shellholder
on original rim, put in bushing for shotgun primer, which
fires off RE17, the turn case and rim a little, and slip
on basecup with epoxy inside. Then take a 200 dollar heavy
barrel NEF 10ga, and deepen chamber like mine is.
Here is picture with one beside a 12ga FH. The 12ga FH holds
max load of about 330 gr ball powder below a slug,
and the 10ga FH holds 420gr. I'm getting things set
to get a bunch of cases to do this. Progress.
Now anyone wanting any of my cases for their collection
I have a package of them all. Contact me.. ...Ed

Re: 12GA From Hell

The long brass 10GA FH case shown above has a Lyman
slug in a thickwall 10ga steel shotcup that BPI sells.
That's a 12ga 525gr Lyman.Makes nice lighter slug for 10ga.
The slug has bottom chamfered to set in cup tight
and a little epoxy makes it one piece that makes it a discarding
sabot style like a SPW. That makes it front heavy so that it
is as accurate as Brenekke KOs in smoothbore. I'm
also working with a guys to cast long hollowbase 10ga slugs
like the ones Federal loads. We are figuring out molds now,
will probably make slugs about 850gr. Here is picture of
my 10GA FH NEF with long brass case started in the chamber.
Chamber is set for that 4.050" brass case and will shoot 3.5"
plastic cases also. I am going to put on a thumbhole Survivor

We talk about liking the use of heavier slug barrels
in using our slow powder giving 1/3 faster loads
in plastic cases, and handling recoil better. It is
stiffer being heavy for an aid to accuracy.
Guy out west has this heavy muzzled, Hastings, rifled
barrel, for his REM 870. In first pic is a comparison to the
original 870 barrel. It shows a muzzle as heavy as on
a NEF Ultra Slug GUN. 2nd picture is the gun itself.

Re: 12GA From Hell

On another thread here is concerns about the
MRC PH action. They have couple hundred all done, but
waiting on the firing pins, which are being made now
and then will be heat treated and delivered.
And them he can assemble our actions, adjust pins, test the safety
as fast as they can, and be sent out.
The company making pins went bankrupt, with Jeff having
paid for tooling and 600 pins(for PH and other actions) and they didn't
deliver order before going bankrupt. I have picked up 4 extra actions
from guys who went on to other guns. They are a good actions
for big cases. It is only been 2 years since they started
actually making these and 22 months since they charged my card for
first one.They designed them years before, but things with others in
the firm just didn't help get it going.

I paid money with the knowledge that it was to help get
these actions in production, knowing it would take time, as many
things in the gun business does.While he was making these, he had to
buy out people so as to get busineess going in right
direction. He had avery few PH pins on approval, and he tested first
PH last summer and sent it to me to put my hairy 700HE in
it to test, and I tested it with a 65,000 psi load, Tested ok.
Couple weeks after, knowing pins work, he called to get the rest
of order and got a bankruptcy lawyer. And no pins or tooling.
I know I'll get my other actions. I got more patience than most,
but Jeff has done yeoman job considering folks he had to get
out who didn't seem to help, considering the heat treating took a while
to get perfect( heat treating co fault), and the supplier problems.
Also He is in process of making a complete fully equipped shop,
getting all CNC stuff to do all of his small parts in house ,by the end of
this year.

The heavy rifled barrel in previous post was made by
Hastings for the Remington 870. It is 26" long and a
muzzle diameter of over an inch. Hastings is gone now,
but we'd like to find some of these barrels. The Hastings
number of the barrel is 560H90.

In the meantime Remington has come out with their
SPS Super Magnum Slug Gun with 25.5" rifled barrel and
a 1" diameter muzzle, with more solid barrel, and extra
pins in mounting barrel, so a scope can be put on action. Ed

Fired the 4bore with the 760 gr round ball,
which is a hard rubber coated steel ball,
thus the light weight compared to lead,
using 100gr of Blue Dot under 300gr RE17,
total 400gr. Hairy load, with 3500 fps, and
20,000 ft lbs. Used the turned 4bore cases,
with shotgun primers, and with that light
projectile case doesn't need sizing. This is
good beginning bullet weight for early testing.
I am gonna do 1200gr and 1600gr holding the
speeds to give about same energy.

Re: 12GA From Hell

Ed- what sided ball would make a buckshot load in a 4 bore? That is, 3 or 4 layers of 3 balls that fit the bore in a triangle? There is probably a mathematical equation for figuring that out - it is beyond my match skills.
Just a gues is that .50 cal balls might work, ie: .595". Those would weigh about 182gr. X 9 = 1,638gr.

Sounds about right and what a deer/bear load - or for repelling pirates.

Makes 3x 44/45 cal in a 1" 4 bore. Or 420 grains per layer.

Three 45cal lead MZ balls near perfect in 1" 4bore

Re: 12GA From Hell

Heh, heh - you're thinking of speeds I hadn't considered.

12 balls, 4 layers would give just about 1,600gr. weight, about the same as a single 4 1/2 bore ball would, for a muzzleloader.

Of course, the rifle's action will allow more pressure, higher velocity - and a paper wrap or two around the balls, ie: post-it note paper from a pad might help hold them together a bit longer for better patterns.

Interesting concept.

The 4bore/ga is smoothbore for now, so
a shot pattern might be fairly good.
The speeds we are talking about are possible
due to the smooth bore and thumbhole stock
and good weight and balance. It is 28 lbs,
thick pad, and ported. For hard shooters a
thumbhole stock is best.Ed

Re: 12GA From Hell

I guess I should have said the 'Gun's' action, not the 'rifle's' action. I meant gun.

Since you will be using normal wads, a jug-choke of about .020" will improve patterns and I found in a .44 smoothbore with .005" jug, it didn't hurt RB shooting in the least. Others with jug chokes in muzzleloading 20 bores get good results with round balls and shot.

Should also be easy to make nylon or HDPE sabots for a 1" bore. Slit lengthwise like a BRI sabot, they would expand or split out upon firing to touch the bore itself for straight guidance & release well at the muzzle with a mild cone cut in the nose, like the BRI's.

About any large projecile could be used, I guess - how about 3, .735", 600gr. round balls for a buck-shot load?

That ought to leave a mark on something at 1,500fps to 2,000fps.

Re: 12GA From Hell

Hardened rather than pure lead would make ideal hard cover penetrators at that speed, Ed.
A slightly hardened 15 or 14 bore ball, small in comparrison to your 10 bore ball, driven at the low speed of 1,400fps will penetrate "Through and Through" an (Indian) elephant's head.

Solid concrete blocks are fun to shoot with hardened balls at descent speed. i reduced one to rubble with 1 shot from my 14 bore rifle. The block was 14" X 12" X 4" thick. The largest chunk was about 3" in diameter. I still have the ball as it was laying on the ground amidst the rubble.

At an initial 2,300fps, WOW!

Re: 12GA From Hell

I got my 20ga FH 3.5" brass cases from RMC.
The case capacity in water is 234 gr.
It holds 215 gr of dense ball powder to the
base of 490gr 20ga hard lead slugs I have.
These cases use a 209Mag shotgun primer, and
I have mouth ID set up for .620 slugs as the slugs
and sabots I have are that size. These cases will
work good out to 35,000 psi, without extreme
expansion or resizing problems. Load of slow powder
will get 490 gr to 2500 plus at 25-27,000 psi,
6800 ft lbs, using the 30" barrel I'm getting to
put on the FBW Model L falling block.
! also have a case of the 3.5" factory Hastings
SPW, locked on sabot, loaded rounds to use.Ed

Re: 12GA From Hell

Transition, biggest to a smaller, in
putting falling block actions in one piece stocks.
First one was the 4bore, the big one in
picture and after it was done I got a FBW falling block
and soon figured out I could do the same with it.
It is chambered in my 585HE cartridge.
And it is pictured above with the cases.
I built the 4bore, from blocks of steel.
The FBW is the Model L, and I'm doing second one
in 3.5" 20ga, to use brass and plastic cases.
And maybe later on when I find extra 700 barrel
we'll do my long 700HE in FBW....Ed

Here is picture of FBW Model L in one piece stock,

Both are chambered in my 585HE.
These two plus the Wickcliff 76 and Ruger #1
will easily handle my 585HE with proper
weight and thick pads. These guns have
rimless extractors and my 585HE goes in and
out with least amount of metal removal from
the feed trough, with much more power.
The Model L will have a 3.5" chambered 20ga
barrel to use 3.5" MRC brass cases and
Hastings factory or reloaded plastic cases.Also
I'm working to put a Wickcliff in 1 piece stock.Ed

Here is picture of a cast .504" slug BPI 12ga sabot
a guy made a few for me and it has good accuracy with
our slower powder loads, with the sabot working ok.
Slug is 440 gr and hard alloy cast with decent
meplat for good penetration.But it isn't too blunt
so it has good longer range capabilities when you
get the speed behind it. Soon be the deer season and
guys are still hunting for their ideal 12ga sabot/slug

Re: 12GA From Hell

The .504" lead slug I show for using in 12ga sabots is
one cast for using in .500" cases like my 499HE, by
sizing it after casting. Tried it at the .504" diameter and
it works in the sabot also. So it does double duty,
unsized 12ga sabot, sized and lubed in .500" use.

Some like short cases in big calibers, and have put up
various ideas. First picture is 12ga brass cases, two
2" long and other 2.25". Cases made by shortening
our cases we made by putting rims on bmg brass.
These can be used in Savage 210 and feed from mag
box. Can use 2.5" Magtech brass shortened so case
and protruding slug will be 2.7" overall and feed from
magazines of Savage & Mossy bolt guns. With 2.25" case
you can get 600gr to 1800 at least.Ed

Have had a bunch of different guys shooting
the 4bore with light 11,000 ft lb loads.
All say it is a tremendous thrill.
Simply the greatest shooting ever.

So many have opinions on what is a real big bore.
I think really big starts at .585........
So in that vein I have made the 585 Hubel
Super Magnum, 585 HSE, giving a nod to necked
cases.Also can make the 620 HSE for 600 guys.
This is my only wildcat base case with a neck.
Base and rim are .750", shoulder is .720".
and case is 3.7" long. Power in the range of
14,000 to 17,000 ft lbs. Can be used single shot
in the PH, the Savage 210, the Enfield. Not for
mass production by me, cases too hard to make.
An experiment with necked cases.

years ago by 450 Ackley here on NitroExpress forums. They
need heavy barrel in place of original. It has a rifled
Pacnor barrel and weighs about 9 lbs. In my measuring an
action here, they will feed a 3" brass case with a protruding
slug, like the cast Dixie or the Henson jkt slugs.

strong enough with 3" RMC brass to get 730gr slug to

treated. Nice design, one wide groove, for lube if needed.

Re: 12GA From Hell

Comparison of slug type and speed for accuracy.
Comparing better 12ga slugs for rifled and smooth.

The US-S 570gr slug, with
locked on base does 2-3" groups at 50 yds
and about 9" at 100yds in heavy barrel.
At 2000 fps in smooth bore.

Now a Dixie 600gr slug in rifled barrel at 1300,
2-3" at 50yds- about 9" at 100yds;
BUT Dixie at 2000 2-3" at 50 yds and 6" at 100 yds.
It seems that slower slugs in rifled barrels losing velocity
gets below the speed of sound at 100 yds which
affects accuracy. Of course super heavy bullets, like
12-1500gr, make it harder to start out fast
enough to be supsonic at longer ranges.


This accounts for the guys info I posted earlier about his
high speed in rifled 20ga killing deer at 160 yds.
And holding tighter groups at longer ranges.
He kept velocity above the speed of sound
further down range......Ed

Ed - I aquired a factory rifled Mossberg M835 - unfortunately, it has a 3 1/2" chamber. I've tried some 1,600fps loads in it with round balls in 2 3/4" cases and received a single 1 1/2" hole for 5 shots - but only shot at 30 yards. I was wondering if you'd PM me some of the loads used in the protruding bullet 2 1/2" magtec brass mentioned in the above post. I am tconsidering of starting low and then working to a 3" load (shortened 3 1/2" cases), either rolled crimp or folded. The longer case should be more accurate than using 2 3/4" or 2 1/2", of course.

I have 2, 14 bore moulds at this time, an adjustable one hemispherical nosed 560gr. to 1,000gr. that can be swaged to the Mossey's tight 12 bore that I made for my .69 ML rifle and the 730gr. .69" minnie that can also be altered through swaging to a larger size to fit as necessary.

Also, I have appropriate sized round ball moulds that fit this gun using gas checks as rifling-taking cups in .684 and .710" as well as a larger .724", which is groove size. The gun's 36" twist is more suitable for a slug, even though the round balls seem to shoot well in it.

Re: 12GA From Hell

I would say your fortunate to have rifled barrel with
3.5" chamber. You can do so much more in the way
of wads to cushion keeping peak pressures down
and making cases last longer and resize easier.It
means you can load brass cases with protruding
slugs about 3.1 overall, and use the magazine.
So with Magtech 2.5"brass don't cut it off, and with
600gr slugs use 95gr of 4759, 100gr 4227, 140 gr RE17.
And you can use same loads in 3.5" plastic, with roll crimp.
Of course fill space with seals and wads.Ed

Re: 12GA From Hell

Got asked about slugs going from supersonic to subsonic.I understand
it is that blunt bullets that are in most shotgun slug/sabot loads,
do not maintain best accuracy when passing back under the speed
of sound like spire point bullets do.Speed of sound about 1150 fps.

Now on, FED 239 primer in 8bore and the 4bore cases I have
with shotgun primers. They almost as strong, from my primer tests
as the kiln primers from WIN and REM.And they seem to dent easier
in my 8ga testing than FED209 or the REM kiln ones. I get them from
the 3.5" 10 and 12ga Fed primed magnum cases. Makes ignition surer.

Lotta guys want to try Magtech 2.5" 12ga cases. Well they are
stronger built than any of the old time brass cases I have seen.
About dollar each, go in same chamber as plastic, same strength.
The rifle looking cartridge in a slug gun is what some like..
If you have break action load them with protruding slugs any length.
If auto or pump in 3.5" chamber load them up to 3.1" overall
with protruding slug and you can feed from magazine.
RCBS has sizing dies. Ed

Re: 12GA From Hell

Ed - I understand it is the long pointy high velocity bullets that are disrupted most passing from super sonic to sub-sonic speeds.

The least effected, is a round ball. As the length, shape and speed change, the more they are disrupted.

Case in point, is my RBlock in a heavy barrel .50 Alaskan chambering. With black powder loads being shot over a 200 yard range, they go from super sonic to sub sonic, yet with tang mounted aperture and globed front sight, it shoots better at 200, then at 100 meters using a flat nosed 550gr. bullet. At 100 meters, it runs 1.4 MOA, but at 200 meters, it's down to .7 MOA.(1 1/2" for 5 shots, both ranges - 109yards per 100 meters)

27/08/10 01:18 AM
Re: 12GA From Hell

But all bullets are down to 1150 fps when starting to go subsonic.
No matter what they were started at.

They have the most disruption(wobble), I understand at the point
of going subsonic and if started like a lot of blunt shotgun slugs
at 1300 they are going through that change at 70-100yds.
After that they settle down and don't wobble so much, but 12ga slug
trajectory, at 1300 slow start, is terrible so most guys don't use them at longer ranges.
Hence the search for speed so they stay supersonic out to 200 yds.Ed

(.224 member)
01/09/10 06:58 AM
Re: 12GA From Hell

The wobble is caused by the bullet passing through what is called the transonic range. The range of speeds between the speed at which one point on a body transition from supersonic speed, and the speed at which all points transition from supersonic speed.

I found some 4bore plastic cases, 4 inches long, red

plastic without a steel insert in the base like Activ cases

They are the size for the 4bores that are about
.950 inch bore. They are suitable for shot loads of moderate
pressures. Guys loading them say they stretch out after
a few loads. And they use about 3 oz shot.
I will test them with a light buckshot loads
of nine 45cal buckshot, 140 grains each.
Total 1260gr, a little less than three ounces.

The original minnie ball for the (mostly contract) rifled .69 muskets prior to the Civil war, was hollow based of course, .69 cal. and 730gr. If these fit 10 bore wad cups, they should be an accurate bullet of decent size for a rifled 10 bore. Lyman makes the mould, still. I have one, but have not tried any in my .69 rifle as of yet.

The .69's were the most accurate minnie rifles in the arsenal, outshooting for range and accuracy, both the .54's and .58's.

Using 395 gr sabot get over 2700 fps. 600gr
over 2200. Cases take many reloads with
minimum sizing. One fired 8 times, still good
and the slower powders get the velocity
without the hard shock to cases, compared to
fast shotgun powders. And the hotrod Hastings
factory loads work in the gun also.

Re: 12GA From Hell

I like singleshot break actions. I found another brand that will work
to make heavy barrel 12 and 20 ga FH. By monoblocking in heavy
barrels. It is the CBC Model SB. It has stock mounted like more
expensive doubles and O/U. And nice shaped pistol grip stock.
They have the nice stylish look like the Win 37 and Stevens 94.
But they are heavier built, just need heavy barrel.
I going to do a couple by monoblocking in heavy barrels, one 20ga
and one my 585 HE like I did in the NEF.And they are 50 to 100 bucks.

That action is a 1/8 inch wider than NEF, has big breach diameter
like NEF 10/12 gauges. The bearing surfaces on the pivot is .300"
wider, and pivot block is 1/4" wider. Pivot pin is 1/10" bigger.
The action is a 1/2 inch taller, and extra diameter at breach end.
In fact you could build a real hairy 8ga on its wider action, with
a heavy barrel and a new pivot block welded on.Ed

More info on 10 and 8 gauge slugs. The guy got some
made with deep hollowbase, 10ga 900gr, 8ga 1100gr.
He will make them for a buck each.
Bob Bigando in AZ. (bobiano at yahoo.com)
Good price as they are nice hard shiny slugs.
For seals for 10 and 8 gauge you can get regular
card seals and nitro fiber wads, but plastic seals
will do better, about a 100 fps in the faster loads.
Plastic seals for 10 ga are at BPI, called - X10X.
For 8ga I cut bottom seal part off of the 8ga wadcup
that BPI has. For extended accuracy in smooth bores
you can screw the seals on to the slugs and that
will make the overall projectile more front heavy.
Or better yet screw nitro fiber wads to the slug,
like the Brenekkes are. Good smoothbore accuracy
Use slugs with seals on, with slower RE17 that fills
case so no fiber wads are need.Just seal and slug.ED

Re: 12GA From Hell

I talked about these 12ga jacketed full bore slugs earlier,
shown below. Well now BPI has something similiar in
their new catalog. We have tested some and one
gets a 3 shot group that is nearly touching at 50 yds
in a scoped NEF Ultra slug gun. They can go real fast in
our 3.5 RMC or our real long case.They are hollowpoint
and fairly streamlined.I fill them with plastic glue for
better streamlining.Fullbore and no sabots needed.
Relatively light weight, to lessen recoil.Ed

Re: 12GA From Hell

Jackets are soft copper, so they'd give some.
Start loads down a little.
The 12ga Brenekke slugs with locked on base and the USS-S
slugs I test have led to other combinations that I've put
together using different slugs and wads. The object is
60 yd accurate, economical slugs for reloading smoothbores
that in the reloading process we can get more power also.
Like the Lyman cast slugs in thickwall 10ga steel wads,
with the slug glued in and wad cut off even with top of slug.
Then with wad cut even, you load and can rollcrimp perfect.
It makes a real nose heavy combination that is as accurate
in smoothbores, as the expensive 10ga foster style slugs.
Another one is the hollowbase 577 soft lead slugs that Dixie
sells, I put in a thickwall 16ga wad that BPI has. I glue it in
using Goop, a thick glue that hardwares sell. Epoxy works.
Another one is 20ga ga thickwall wad with 54 cal hollowbase
soft lead slugs. All these and others can be loaded for a fifth of
factory for smoothbores, and be as accurate as foster slugs.
And our slow powder loads seal good with wadcups.
Representative one in middlle, 10ga.Slug glued in tight.Ed

Re: 12GA From Hell

Penetration with slugs-Had a bunch of
wood blocks up to 12" through.

20ga load is a 54 cal 410 gr slug glued in wadcup.
Gives the same effect as Brenekke with locked on base..
Good in smoothbore at 50 yds.Goes through
6" block of wood easy/

Buckshot load in 4bore, 9 140gr 45cal balls at 1800,
all zip through 3/4" OSB and keep going.
In 4bore 760gr steel ball zips through 12" block of wood.
going over 3200 fps. Wood is dried hard poplar.

In 10ga 3.5" plastic case, a 900gr hardcast slug at 1800
fps, through same kind of block easy. This slug I put
on a screwed on base with plastic seal and wad.
I've also put plastic seals and fiber wads on 8ga
slugs to test later..These 8 and 10 ga slugs with
seal and wads locked on to them are for smooth bore
use. My 10ga and 8ga are smoothbores.

12ga 600gr hard slug at 2100 zips through 12"
wood block like it was putty.In a 3.5" RMC
case in NEF.

Anyone wanting one of my loaded 585HSMs to
collect or look at, let me know. 750gr
slug in this at 2800 in Enfield test gun.
Soon have barrel in PH and put the real
speed to it. About 33-3400.

Will soon have the heavy 20 ga barrel mono-blocked
into the 12ga barrel setup on the CBC break action.
Make a nice looking gun. Also going to put the 8ga heavy
barrel I had in Enfield for testing into falling block
built like the 4 bore one.Maybe done by summer.
Will be in one piece stock like 4bore.Ed

Re: 12GA From Hell

Finding real slow powders that works with shotgun primers,
without starter powder. We found RE-17 and surplus 7383.
To recap faster rifle powders we use -VV110,IMR 4759,4227..

On the thread we've written about real slow powders like
H-BMG we've used with a starter powder, IE 15gr of Blue dot,
and H-BMG in amounts from 150 gr to 230gr in 3.5 and 3.85
inch brass cases. And 3.5 " plastic cases. 860-1040 gr slugs.
Tested in NEF with long heavy barrel.

We finally got some RE-50,a really slow powder like H-BMG.
It works with a real magnum shotgun primer with heavy slugs,
860 gr on up, in 3.5" RMC brass, 3.5" plastic and our long
brass case. I used 239 Fed primers. Lighter slugs
only give squib loads.RE-50 Is a powder made like RE-17
with the deterrant all through the grain of the powder,
rather than all on the surface of the grains, so it will ignite
easier, to get the initial combustion started.

In brass case used 240gr with 860gr slug, 1950 fps
and 220gr with 1040gr slug, 1750.
In 3.5" plastic 860gr slug with 180gr RE-50, 1500 plus.
Now these velocities aren't earth shattering as powder is real
slow, but cases don't expand, not even plastic case base cup.
And no starter powder. Nice thing is just fill cases
leaving room for slug and seal and no worries about
to high of peak pressures with the heavy slugs or
cases expanding to stick.

Now to get 239 primers get Fed 12ga long red
3.5" primed cases from BPI. I used Fed cases,and took out
primers and used in other plastic and the brass cases.
Got a big shop trying to free up 239 primers for us reloaders.
Federal puts them in 3.5" mag 12ga loads and 10ga cases.

Elsewhere it was reported someone may do a 16ga sabot.
Also a guy got huge antlered buck with hotrod 20ga. Ed

Re: 12GA From Hell

I have a way to compare primers without powder and slugs,
for a lot of my experimenting. I use a short 24"barrel 10ga.
The barrel being shorter I can see the sparks and flame.
I fire off the primers in case with no powder/slugs.

I have just tested to see if magnum FED Fusion and Triple 7
inline muzzleloading primers were as strong as FED 239.
Just the two brands to test in the 10ga to compare flame,
sparks and bang, and they were not as good as the 209
Remington STS ones I like. They only put a few sparks out
of the barrel.The REM 209 STS and Fed 209 M had 3" fire out the
barrel and the Fed 239 had about 5-6" out the barrel. And 8ga
Rem and Win kiln case hotrod primers 8" plus....

Previous post I mention trying to start H-BMG slow powder with
8ga kiln primers without success. Which is why we figured out
using a starter powder like 15gr Blue Dot. Then it works great
with any shotgun primer. Guys here when they see misfires with
shotgun primers and H-BMG only, and the see starter powder loads
go off in our big 12ga case like a tank cannon, they are
flabbergasted at the difference.ED

Re: 12GA From Hell

I mentioned in the threads earlier a 16GA FH case
I made from bmg brass. Then I put it in a 16ga
Stevens 94 break action by lengthening chamber
for the 3.5" case. I kept speed and pressures down
as the regular barrel on the gun had a thin muzzle.
Now I found a thick heavy 16ga 32" alloy tube and
I had extra Enfield test action, with the port
opened for longer cases. I turned it 1.1" at the
muzzle. Nice and heavy. It does a 630gr 16ga
'Greg S' slug 2400 and 385 gr Lightfield 16ga slug
to 3000, without the bottom 2/3 of the case
having to be resized. With RE-17. I have these cases
setup for shotgun primers.The Lightfield has it own
seal on the locked on base and for the 630 gr use
a BPGS and Flexseal over powder.. Ed

It is a BPGS type plastic seal, IE, a one way seal,

Here is picture the CBC 20ga FH setup

into a CBC 12ga breech section.The 20 heavy
barrel is threaded into the mono-block made
by cutting off 12ga barrel. These CBC actions
are taller and wider than other break actions
and the locking lug block works better and
nicer than other break actions.Also shown
is 20ga 3.5" plastic and brass cases.

Re: 12GA From Hell

Here are some 20ga slugs/sabots we rigged up.
I traded for whole box(hundreds) of 20ga Hammerhead
slugs, in the picture. They had pulled slugs
out of the locked on plastic base, so I glue them
back in so base stays for fair smoothbore accuracy.
And I also glued in various 458 bullets, as shown,
which fit tight in cup, up to 500gr. They discard
on impact. Fair accuracy at 50-70 yds. Less expensive
shooting as I have pile of hard lead 458 slugs.

Idea on 8ga FH. Looked at a TCR87 break action 10ga
and the breach mono-block can take a little bigger
barrel.If I find one I can afford(pricey) I'll do 8ga.
These are very strong actions, a little smaller version
of the action setup Colin put the 2bore in.
Just put in straight 8ga bull barrel like NEF Ultra.ED

The long brass 8ga cases have same thick

plastic/paper cases out there, but they
are scarce. Thick sides mean a good chamber
fit, so as to minimize case expansion and make sizing
easier. Here is picture 8ga and 10ga fullbore slugs with
locked on basewads that I setup. Wads held on by
screws and slugs hollowbase as well, so to work in
smooth barrels with some accuracy. 8ga is 1100gr.

Re: 12GA From Hell

New super strong 12ga bolt gun just out, Savage 212, taking
over for the 210. You know I did my first 12ga FH in a 210 and
have posted that sometime I'd like to get a thicker walled
reciever built to have more strength and safety.
Well Savage helped us out.

Its reciever is 1.5" diameter, where the 210 was 1.36" dia.
I has a large .900" diameter bolt, where the 210 had regular
110 bolt inside bolt carrier. It has a fitted bolt head like 210
and other Savage 110-116 rifles. Only its bolt head has two lugs
where the 210 had 3 lugs. Its two lugs about 90% strength as
the 210s 3 lugs.Its about 12% stronger lugs than Enfield and
Rugers. Also it appears the bolt raceways are not through the
barrel thread area so about 50% stronger barrel connection.

Price not too bad 500-550. I'll try to find one later to do some
hairy cartridges in. It has a 3" 12ga chamber from factory and
detachable magazine. Probably can have mag and port lengthened
and feed ok, with 3.5" 12ga and the 700H 3.25". More info
as I find out stuff.Picture from auction-e.Thanks to
Bob in OR for info.Ed

Re: 12GA From Hell

Some more info on the Savage 212. I looked at one,
got more measurements. The port is 3.812" long.
Can be made longer. Bolt travel is 4.625" and can be .50"
longer. And with full diameter bolt can have extra
lugs in back. The Mag box has room for extra length in
front of it and behind it. It could work for 12ga FH
and 700HE long case.

A fellow on Gunsmithing forum found a way to make
jacketed slugs using copper tubing caps, the solder ones,
by putting them in a die and using a shaped punch to form
a round nose copper jacket, that can be filled with lead.
He made .700 cal ones, different dies/punchs could
be made .729, 12ga size. I got a few here and going to see
what is possible. I got bigger caps also to see about 4ga
and 8ga ones. Here is picture of the CBC break action with

I use 630 gr full bore slugs and the 385gr SPW
saboted with locked on base.

Opened port and changed bolt stop. Reamed
front so case fit through action into barrel and added extra
rear lugs. Same process that is used to do Enfield

Re: 12GA From Hell

Experimenting for fellows trying to get speed with heavier sabot slugs than
the lightweight saboted 4-500 gr kind of slugs, in 2 5/8" length brass
cases for where length is limited..

Using 770 gr saboted slugs with locked on base, by US-S.
Thes are long saboted slugs due being brass and locked on base.
Real hard to do with these due to lack of powder space for the RE17
and IMR 4759-4227 that I like to use. With 770 gr and 60gr 4759 got 1450 fps.
With 75gr Re17 about 1350 fps. Both of these all case will hold under sabot.

For contrast using full bore 730 gr Dixie with just seals under it, much more
powder room, with 95gr 4759 getting 1800 plus and 130 gr RE17 1700 fps.
I went to faster powder, my slowest shotgun powder, Alliant steel, to try to get
speed like full bore slugs get.

These listed are max loads before brass cases expanded to much and started
sticking, due to sharp expansion step, where the base goes to the side with a
real small inside radius on this particular RMC brass case.
47gr Steel,and 770 gr slug 1400 fps.

So I tried the 570 gr US-S with 53gr Steel,and got 1700 fps. Same slug with
65gr 4759 got 1650. You can put in more Steel but cases stick.
And cases expanded that way are hard to resize.

The first 3" brass I got years ago, same problem with
a sharp step expanding above the base. So when I had 3.5" brass made
I had them do a long inside radius from base to the sides. These with extra
room for powder and cushion are much less problem. I think where you have
to use shorter cases, you can use plastic, as a 3" plastic is 2 5/8"
when crimped and will do the same and only be 20 cents or so new.Ed

Re: 12GA From Hell

Answering questions; bullet jackets from copper tubing
caps. This process makes jacketed slug with covered
nose. With heavy soft jacket as opposed to a
solid turned slug from solid rod or soft lead slug.

1/2" caps can make .700 and 12ga size jackets.
5/8" caps can do 8ga and maybe 10ga jkts.
And 3/4" caps can make 4ga. These cups are
malleable enough to shape into jackets,
without a 20 ton stamping press.

We used the heavy 8ga barrel that I first
put in the Enfield bolt gun for a 8ga testing. The breech
block, linkage, lever, pivot is done, as you can see
in picture with lever open and breech down.
I have got to chamber, put in firing pin, do
hammer and trigger. 8ga gun in 1st picture.

Hammer and trigger setup is now mounted and moves
on the back of the breech block on an extension.
I also made this change first on 4bore, 2nd pic.

Here picture of the 8ga from back. This action will also
do 12ga FH, 10ga, 700HE, 600NE,50BMG,etc. The breech
block in this and the 4bore are 1 inch thick front to back,
with the width different. The bottom of block is same on all
and uses same linkage and lever; same hammer and trigger.
The 4bore one will do 20mm, as that is what I make
the 4bore brass from. When I do 2bore, breech block will use
same design, but just be wider on the top of the block.
The recoil pads are over 2" thick. I made the stock
from a 2.5" thick blank......mostly by hand.

This action will hold much more pressure that the heavy
built plastic 8ga cases can take , and they are good
to over 20,000 psi. Like a 1000gr at 2500.Ed

extensions are narrower than the top. These are
what the linkage is inside of and when breech is
levered down these fit though the slot in the stock.
And being narrower the slot isn't too wide so the
stock has enough strength. Botton extensions same
width for all action sizes.Just top different
for the size of action needed for big cartridges.
This breech is little rough as it has had a dozen
changes to it. But it holds a load in 4 bore
of 1500gr over 2600.Ed

versions, planning on getting around 2500 fps with
shotgun powders. I know in our 3.85" case in the long
barrel Savage, I could get over 3000 with big amounts
of our slower powders we load with.

Bought some tubing caps And here is picture
of those copper tubing caps, you can make bullet
jackets out of, and fill with lead. In picture you see
a rough one I formed with punch, and with a die they be
perfectly formed. And with right die they could be
formed with round nose with edge step for perfect roll
crimping in plastic. And on the right see big caps that
would do 4 bore.There are caps between the two sizes
that would do 8ga...Ed

Re: 12GA From Hell

More 12gs slug/sabot info-- About discarding sabots.
Most factories making sabot slugs make them relatively light,
300 to 350 grains, and that is why they are on average
more accurate than what guys try to reload with heavier
slugs in the sabots. Reason is light slugs don't damage
the sabot, while they are trying for high velocity.
Example is picture of Hornady SST sabot and it only has
a one way plastic seal over powder, and a hard
rubber cushion inside the sabot under the 300gr jkt
spitzer style slug. Many 12ga hunters say these are
the most accurate.

Another slug idea is a blunt nose jacketed slug of
675gr I made from one of RG's hollow point jkt slugs.
I cut part of jacket off of the front and swaged
it over to make blunt nose. These are for the guys
trying to make short loaded brass case rounds
in 2.5" brass and 2.62" brass to be no more than
2.75" overall to work in certain guns. it is
on left, 2nd pic. And gets good velocity with just
good BPGS seals under it and slower powder.
On right is US-S sabot with discarding petals, locked
on base we tried in short brass case, and can't, due
to length of sabot get in enough powder to get
the higher velocity with heavy 700gr US-S slug, the
guys want to get.....ED

Re: 12GA From Hell

Here is picture some folks wanted of our
big cases with smaller 30-06 for comparison.
In picture, 1st my 2ga, 4ga, 8ga, 10ga, 12ga,
my 700HE long case, my 700H 3.25", and 06.

2nd picture is short 2 5/8" brass cases we
are checking loads in, to see how much speed
can be gotten.You can easily see the length of
short full bore lead slug, compared to the
saboted ones, allowing more powder in the short
slug load for more speed..

Now this doesn't mean saboted are no good, or
that I don't like these saboted types. Great for
smooth bores, the US-S with locked on base, are
the best there is, I think, for big game.Just
got to use longer cases. I always felt, that going
longer cases is worth the effort where practical ED

Re: 12GA From Hell

Here is picture of my big 585 cases.
30-06 for size comparison.
3rd is 585HE - I have it in bolt, falling block,
break, etc, actions.

1st is 585 Hubel Super Magnum - Designed
for strong bolt guns. Have in a MRC PH.
Can get 20,000 ft lbs.

2nd 585 Rimmed Hubel Magnum and I have it
now as a single shot in an 1887 Win.
The 87 has a 30" heavy barrel. Case is
designed to use in break actions and run about
25,000 psi, but due to the size of the case
has enough powder so can get 15,000 ft lbs.
It is 4" long, could be called 24ga FH.Ed

Re: 12GA From Hell

That 585 belted case (from the left next to the 06) has same bolt face as 505Gibbs and will fit into unmodified CZ550 magnum bolt action. It will feed from a staggered magazine just like the gibbs in the CZ. Looks and works like a scale up 458winmag/Lott just fatter. And the same idea as the 500 A square. The Lott and 500A2 two of the modern best big bores. The 585HE makes three. A very clean and simple design, with no rebate, no problems at all. Perfection. The 577/585 handles some really big bullets and wild heavy loads or can still be loaded in at a practical level for a realistic hunting rifle with 577NE plus loads. That practical option, without a muzzle brake or 16-18 pound gun weight seems a real plus to me.

It is IMHO, the best in class, best of all the over 50 designs. No compromise and quite practical if you can say that about any over 50.

Between 50 and 58 caliber there are only odd ball diameters and over 58 will not fit properly in the CZ550, or requires major rebated rim and single column feed. The 58 bore is simply the best fit.

Just an opinion, but I am big fan. IMHO - Ed really has a potential winner in this one.

Some 10ga experimenting with slug loads.
In NEF with 32" factory, long bull barrel.
It is smooth so we use hollowbase slugs

Cases FED 3.5" plastic cases, roll crimped.
900gr full bore slugs -180 gr RE17- 1800 plus.
Use plastic powder seal and fiber wads.
Slug hollowbase and hard cast.

740gr 69cal hollowbase soft lead slug, in VP100
10 ga wadcup. Deep hollowbase slug ..Wadcup has own seal
and cushion. 180 gr RE17 -- 2000+ fps.

Here are pictures of a couple other different guns in
my long 585HE cartridge.. 1st is Olympic Arms
BBK bolt gun, in a target style stock with palm
swell pistol grip...2nd is the one I made on a CBC
single shot by mono-blocking in a heavy 585 cal

Re: 12GA From Hell

Some 28ga FH info and ideas.
Brenneke now has 28ga slugs, with good speed,
decent smooth bore accuracy. About 260 grain
slugs. SAme style as their 12ga ones with locked
on base.Work in 28ga NEFs of course and
28ga O/Us.Some real good 28ga O/Us out there.
28ga is a .550 Inch bore.

But now Rossi has out, a revolving 28ga shotgun
with about a 19 inch barrel. Should work ok with
those slugs. You could also get RMC 28ga brass cases
about 2 3/4" long, maybe 3", depending on chamber,
a shorter version of our 28GA FH 3.25" case.

Maybe I get one in the future, and put on a longer
heavier 585 cal barrel and set it up for my
585 Short HE. Neat gun.Called Circuit Judge....Ed

Re: 12GA From Hell

I found a picture of 28ga Rossi Circuit Judge. Barrel is
smooth bore , could be little heavier barrel, but it will do
ok with the new plastic case Brenneke slugs,
260 gr at 1450 fps..Could do 2000 in a little longer
brass case from RMC.

28ga is a 550" bore in a rifled bore.
24ga is about .585 same bore as my 585, and
most all 577/585 stuff. The 28ga chamber with minimum work
would fire my shorter 585 with a switch barrel 585 bore.
And still work with 28ga with 28ga barrel put on.
Difference is the case thickness with the 28ga case
being nearly the same OD as my 585 drawn, stronger
brass cases.

The Brenneke slug has along locked on base and seal,
connected by long post, that you can see inside
the case in picture and pictured on the box
Quite a long tail so to speak for
good smooth bore work.This is a great step forward
for 28ga slugs, as most reloading slug stuff was only
100 grain balls or other super light slug designs...ED

Re: 12GA From Hell

The why is to make bigbores with big power,
in affordable ways, in innovative ways.


Some have a need for supply of full bore 12ga hard alloy
slugs about 620-650gr. So a couple guys are opening up
their Lee Key Slug molds to full bore .729" It will still
have the partly hollow base and key. I will do the
short brass cases with the first ones I get, to get loads
developed. The slugs are about same length as
the 730 gr Dixies.They have blunt round nose and
can be roll crimped in plastic cases ok. Load of 90gr
of IMR4759 in the short brass or 3" plastic cases
will get 1800 plus in 24" barrels.
I'll Have pictures later to post.

Also here is picture of my 585HE in a Khan
shotgun action. Operates as a straight bolt,
straight pull action for now. Barrel is heavy,
30" long, the butt is weighted. thick pads,
it fits nice, looks great. Ed

Re: 12GA From Hell

10ga FH ideas..Ok I think the most stylish guns in the world
are nicely built over/unders. And there is a heavy duty
10ga over under made by Armi San Marco, imported by
Cape Outfitters. That is one brand I've lately
seen some sold on GB. Others just as strong are Armsport
shown in the picture below, also
American Arms, and Richland Arms.
And probably a few more.

I'll be trying to get one I can afford, I could
ream one chamber for 4.05 brass case
for slugs, and leave other for 3.5" magnum shot and slug
loads in plastic cases. But if we left both 3.5" you'd
still have a hairy gun. You can buy 3.5" new plastic cases,
with hot Fed 239 primers for 22 cents each.
Make a real great combo gun.For slugs with
the right weight slugs.Don't go real heavy.

For slugs use the hollow base hard cast lead
900gr in brass case, at 1900 fps,that the
guy in AZ makes.In plastic about 1750.
Those are not a full bore loads,needing real thick
barrel, but that heavy O/U has barrels ok for that,
keeping pressures at mag shotshell levels.14,000 psi.

These modern O/U actions can take pressures like the
heavy duty NEF SB2 10-12ga frame, if barrels were thick
enough.20,000 in 10ga. IE the actions are real strong.
Ruger has made O/U rifles on their O/U frames,
and others have made big bore rifles
using modern over/unders. I like idea of O/U
double ten slug gun knowing the speed we have
gotten with our slow powder slug loads....Ed

Re: 12GA From Hell

Some newer slug ideas coming around. First is Brenneke,
a locked on base ounce slug in sabot at factory speed of
16-1700 or so in 3" plastic.Really go in our 3.5" loads.

Second is Federal Deep Penetrator, 1 oz, copper plated
and a harder lead alloy, than Federals regular slugs.

Third is Dupleks, steel slug riding on a plastic band,
penetrates very well. About 1 1/8 oz.

Seeing the slug base attached deal from Brenneke,
in a sabot I figured out the following.
The idea is the new BPI blue sabot, being undersize for
12ga, is a perfect fit in a 10ga bpi wadcup, The blue has no
cushion on it so it sits in cup ok and a roll crimp works.
Just shaved bottom edge corner and fits bottom ok.
In 32" heavy barrel NEF 10ga, and 10ga 3.5" plastic case,
gets over 2300 at less than mag shotgun pressures
with 440gr slug in blue sabot.I plan on in future to
make a 10ga with rifled barrel, which these would be best in.

If I can find thin wall 10ga wadcup the 12ga bpi AQ slug
would work even better, as it is for smooth bores....Ed

Hello Ed
I am looking for an affordable 12 guage SXS that I can cut back to 24"barrels and regulate with US-S 570 slugs that I have on the way. Do you know if there are any past or present factory offerings that had barrels heavy enough to handle your reloader 17 loads. Up here in Canada if you want affordable you have to order over the net and take what you get so any help would be appreciated. I know i can get my hands on a good used brno,aya,simson or sauer but they are in warehouses and help is minimal at best.

The side lock BRNO - tradeex has some good price, is probably the strongest action-wise. Many double rifles have been made on them now. Monoblock strength and current barrel strength is the stickler.

He's 6" across front pad so shoul make 7' bear.

Re: 12GA From Hell

Well with 600gr slugs use 80gr 4759 in modern light barrels,
and in barrels .90"- to .94" muzzle use 90 gr.

Here are pictures of the full bore Lee Key Slug
I had a guy cast. He took Lee Key mold and machined
it out to cast a .729" full bore slug. In picture
is a regular soft lead Foster style to compare with.
Slugs are hard alloy and can be speeded up ok.
In 2nd picture is two MRC 2 5/8" brass cases with
slugs in them. These slugs with those brass cases are
being tested first in rifled barrels in a guys 1887 WIN.
The slugs have real good shoulder to
roll crimp against when used in plastic cases.
These first ones are 500 gr. We are going to
work on another die to get the weight about 600gr,
that the brass case guys want to use.
Lee molds are not real high price so it isn't
a bad deal to get them and change them.Ed.

Re: 12GA From Hell

Well then maybe it'll work better with under size BPI sabots.

The first full bore Lee Key slugs were 490 gr,
that we had made. Good for 2300 in 3.5" plastic
and 27-2800 in 3.5" RMC brass cases in the
long barrel NEF.

For the 8ga Hubel Falling Block pictured
above; For now using 3.3" swaged kiln cases. We swage
them to fit the 8ga chamber in falling block.
The barrel is real thick so we can run 50-60,000 psi
if we want in that action. The heavy duty 8ga plastic will
take about 23000 psi. A MRC turned brass would do
35,000 psi. But the plastic does so great,for now I'm
staying with 70 cent 3.3" plastic, primed with 239 primers,
good for 4 shots or more.

And I have the REM wadcup, on left in picture, with
its own seal, that they use for the kiln slug, which works
for various other slugs and shot loads.

In the 8ga HFB - 3.3" plastic cases-
1020gr 2000 -- 900gr to 2200 ---- 770gr to 2400---
and triple ought buckshot load---
9 - 70 gr 000 buckshot, in wadcup. 630 gr total-- 2600.Ed

Thinking of buckshot?- does anyone make 'tungsten' buckshot nowadays with all the non-toxic shot laws?

I'm thinking primarily about those US military 12 bore loads using 'hard' shot - the 7mm load for instance - #3 or #4 buck - .28" in tungsten, supposedly went through an issue helmet at 150yards. They initial speeds were in the 1,800fps range, but at 2,400fps to 2,600fps, that's some lethality! Fun testing, too.

I am not suggesting any illegal use - just the old article I remembered from G&A or some other magazine came back to me when I saw those high speed buck loads, Ed.

them. Over 2000 for 320 gr weight in plastic cases..
3rd picture is an all aluminum version without brass center
from penetration tests. 198gr at about 2500 in plastic cases.
Now the locked on bases are not burnt and the reason I understand
is they use a thin card between seal and powder, up inside the
seal cup.This info and testing by US-S group in the EU.
The plastic cup seal out there might benefit from that, like
card disc inside the cup of the BPGS and similiar seals.Ed

Re: 12GA From Hell

Well we are going to use expanded Lee slugs in the short
brass to have powder room to get the speed the
short brass guys want. That is why I like long cases
as you have more choices like the US-S, regular
sabots, as wel las Lee and Dixie. etc.

In the early days; in my Greener's book he states that
gun with a rifled choke section of the barrel, called
12ga paradox shotgun/rifles, with slugs, heavier powder
charges than shot loads, could hold what amounted to
about 5 inch pattern at 100 yds.

And still had 1800 ft lbs energy at 100yds.
And that is with guns with lighter, weaker barrels
than we have today, so our work is a good extension
of what the early big bore guys did.

IE, head spacing on the mouth and extractor.
Using 600NE .620" diameter bullet and 2.7" long case.
Case could be shorter or longer like the 585 one.
Didn't do much with it as its sides were very straight
only .010" taper of both sides together. Whereas the

they kept weight down so that it could be stepped up in
speed in older doubles, with just short rifling section at muzzle,
that didn't have real heavy barrels. Second picture from Greener
book here, is of older 4 and 8 gauges.

Third picture shows steps of making 4bore case, one inch bore,
from 20mm. 2nd in picture is case with base turned and swaged
to size which leaves base smaller than rim, for rimmed case.
Then 3rd case has top expanded to take 1" diameter slug.
last shows the thickness and strength of finished case.

Testing factory 20ga Hastings sabot slug 3.5" hotrod loads, and
reloaded with 20ga SPW identical slugs, 390gr, goes about 2200
from 30" heavy barrel. Load was 75gr of 4759.

Re: 12GA From Hell

Some info about our slower powder reloads in plastic and
brass cases with shotgun primers for modern 12ga guns.
I now prefer the IMR 4759 over 4227 as we have had
some delayed firing problems when the loaded cases get
real cold with 4227..And with slower powder loads use
magnum primers.

A side note,in same vein, you know I now use FED239
mag primers in my 8ga and 4ga, but we find they they really
solve the real cold gun, ignition problems, in muzzle loaders
using black powder substitutes, with shotgun primer
inline guns. We tested 50cal and a primer sold especially
for ML when fired,no powder, only saw a tip of the flame
out the barrel, a FED209 mag about 4" flame, buta Fed 239
Mag primer about a foot of flame.

Some more info from the old days, here is picture of
a variety of slugs being promoted and used a century ago.
And 2nd picture Paradox cases old and new.Bottom one is a
modern version sold by H&H for slug hunters.Ed

We are always looking for way to shoot 8 and 10s
using easy to get components,cheap, without buying
loaded rounds for big bucks, if available at all.

In 8ga falling block, plastic got 930gr hollowbase
slug to 2300, It is a slug for 10 ga that we expanded
base a little to fit tight in 8ga wadcup. On the left in
picture. At 30 yds 3" group. Just with open sight,
About like the 10ga sight bead. There is enough hollow in
the base it flies pretty good from 8ga smooth barrel.

Along same line, in my 10ga 32" smooth bull barrel with a
750 gr .69cal hollowbase Dixie MZ slug in VP100
10ga wadcup about same speed and same accuracy.
Nice to just get a box of slugs that is in stock,
and a 2cent cent wadcup and Fed 3.5" 10ga plastic cases
and be shooting cheap.And the cases roll crimp nice
down to these slugs.

And also the hotrod 20 ga 3.5" Hastings factory loads in
a smooth barrel moderate weight 20ga shoots about
same accuracy even though they say for rifled, but that
SPW slug/wad combo has enough plastic and seal on the back
and to shoot like aBrenekke. The new 28ga Brenekkes
out of 28ga NEF modified choke barrel shoots same at 30yds.
Scoped guns and good eyes would shrink groups.Ed

Re: 12GA From Hell

A different, interesting style, of 12ga slug, from Russia.
First picture loaded round, in plastic, roll crimped.
Second, two types of slugs they have on the same base.
Base for rifled barrel, little smaller diameter than the front.
Looks like the roll crimp locks against
the edge of the base. Neat idea, and it could have a
flat meplat slug on the front of the base like
the US-S brass slugs fron Greece are on the
plastic bases that I have here. They must use a crimping
die with a deep hollow up in the middle. We have thought
of taking a roll crimper and putting a deeper recess
in middle to load longer nose slugs further out so as to
have more room for our slower powders.ED

Re: 12GA From Hell

Here is picture of 4 long cases of
RIP's on the AR forum.
Top being a Rocky Mtn Cartridge
3.5" turned brass 20ga. In 20ga
getting these and lengthening chambers
allows use of the 3.5" 20ga plastic also.
Some factory guns are 3.5"

Next a RMC 3.5" turned brass 12ga.
Chambered for these you can use
3.5" 12ga plastic also.Some guns are
3.5" from the factory.

3rd down our 3.85" 12ga FH we made from BMG brass.
Bottom a RMC 3.85" turned brass 12ga FH case.




Next picture shows one of the old ways they locked slugs
into paper cases. Many old slugs had a wide deep groove
which made it possible to crimp that way.You can
see one of those slugs in the picture.




Testing 490gr 12ga full bore Lee style slugs in 3.5"
plastic at 2200. Works in the long barrel rifled NEF and
the Khan 12ga 3.5" auto smooth bore.

In same guns the 570gr US-S brass slug with
locked on base at 1900 in 3.5" plastic worked also.
It is great to see a smooth bore slug like the US-S
that is as accurate as most fullbore slugs from
rifled barrels.Maybe they will be imported soon
from European Cartridge.Ed

This picture of an RC4 brand slug I see is available

And locked on without discarding petals, like US-S.

And 2nd picture is a group fired with RC4 slugs
by fellow on NitroExpress forums from
double 12ga, 2 left and 2 rights at 25yds.
I show this to promote the use and testing of smooth

Re: 12GA From Hell

You should have 1700 depending on barrel length.
You can go up to about 95 gr with that weight
of slug/ball. Could you mike a new unfired case
just above the rim, and measure a fired one.
We use that as idicator of how high you can go.

Some more slug and sabot ideas folks are doing.

First is a long pointed slug with locked on base,
It goes to target with base,can work smoothbore.



Second is picture of Hexolit sabot base slug
with petals expanded, sure would make bad wound.



Third shows a variety of Gualandi slugs you can
get for reloading, and we're finding that these
locked base slugs, Brenekke/USS style slugs, are
giving good accuracy in smooth barrels which can
save when doing heavy barrels.Weights shown in
grams, get our weights in grains multiply by 15.4..Ed

Re: 12GA From Hell

I did some brief testing with nylon and lexan saboted .30 cal bullets in my .458 - years ago. I went up to about 3,600fps with a 150gr., but accuracy was almost ruin chornograph each shot deal. The idea has merrit.

Re: 12GA From Hell

I think there is a balance between sabot
thickness and bullet diameter, when
putting them out high speeds,in rifled.
What I mean is I think in your 458 example the
sabot should have thinner sides with say a
375 cal bullet.That is why I am going to see
where I can find 12ga sabots taking 58cal bullets
or maybe 620 cal.I have pictures on soon of
this idea. I think for high speeds there is
such a thing as to much plastic.Ed

Re: 12GA From Hell

I agree - the 'sabot' has limits, but of course, the limits are closely tied with the material being used. The harder the sabot material is, the thicker it can be, I'm sure.

In the .458 scenario, they were making 4,000fps with 220gr. RN bullets. The whole idea (I assume) was to break 4,000fps with a .458 WinMag. using a reasonably heavy bullet. I doubt that bullet held together for very long, but hard to say. Barnes TSX are available in 250gr., but I suspect the friction would be too high, to get much over 3,000fps with them.

A still like shooting bore size, or almost bore size in a shotgun, rifled or smooth.

I freely admit the sabots might have some military applications, for sure - a 12 or 10 bore platform makes for a LOT of diversity in projectiles.

Re: 12GA From Hell

Here are some more sabot/slug and loading concepts.

First is Alcan 2.75" paper case with Dixie 600gr slug,
with the side of the case crimped into the relief/lube
groove of the Dixie slug.The groove in the Dixie isn't
quite as deep as the groove in the Fosbury slug shown
in earlier post, but still seems to crimp fairly tight.



Next are various slugs in 12ga REM sabots that take
57 cal slugs and bullets.Those sabots are from the REM
Accutip loadings. In picture you can see one of the
REM 385gr jkt bullets they use. Also is sabot
with 20ga cast Lyman. On right sabot with hardcast 585 cal
640gr lead bullet, the ones I use in my 585HE wildcat
case. I sized it down a little, perfect fit.
Also the .575 cal Dixie Gunworks lead slugs will do.

Also shown is a long pointed 55 Boys bullet in one,
fairly tight fit.We cut back .3" of bullet off so it
fit for length in sabot and is 750gr.



Third are 3.5" brass and plastic with the REM sabot and
the 750gr pointed slugs in them.In all the sabot work we
and others have done, trying to get accuracy and high
speeds together, maybe there is such a thing as too
much plastic. IE, sabots too thick on the sides if doing
50cal or smaller in 12ga sabots, for heavier slugs
at high speeds. Thinner sides may discard more evenly at
the greater pressures and violence of high speeds.
Thin sides may have less give so that sabot grips slug
better to impart spin in rifled use. Example in
smoothbore use is the USS slugs, where the brass slug
is .629" with thin discarding petals that have proven to
be very accurate. And with both reasonable priced sabot
offerings the last few years being undersize, accuracy
problems, etc, maybe time to try something else.

Got to find whole bunch of these sabots. Are these pictured
12ga REMs the only 58cal ones around? I can't find others,
and maybe we can find where these are made. As I have
huge numbers of the 585 slugs, which by the way I think
is best hunting combination, without extremely heavy slugs
which suffer for the speeds needed for longer range use.
It is hard lead, good for big game.And my guy can make many,
many more if needed whether for 585HE rifles
or in sabots if we can find some.ED

Re: 12GA From Hell

Some more sabot and slug ideas, discarding types
and locked on base types.

First picture of 20ga Buckhamer pulled apart. The bunch
I have were pulled apart, the slug won't lock back in
tight, into the base.



Second is various 20ga sabot/slug ideas some using
buckhammer sabot bases that a bunch of 458 cal lead
slugs and jackted slugs I have, lock into real tight.
The 458 lead ones are 400gr, jkt are 350gr.

And I got some empty SPW 20 gauge sabots, and 20ga
Buckhammer slugs lock into them real tight.I have
many of these slugs. These slugs are 440gr.

Also is 3" 20ga FED factory sabot shell and one of
discarding sabots out of the case. Also a 3.5" 20ga
Hastings 3.5" load with black locked on base sabot,
and sabots out of the case and couple 20 brass
3.5" RMC cases.



Next is variety of 12ga sabots with 50cal slugs
in them.2 white and the pink sabot are FED, The black
is Hornady, With a 50cal long bullet .
The grey, is a BPI with .504" cast 440gr slug.
I wish the BPI was full size like the others
and fit rifled barrels tight for accuracy.........



Last 12ga SPWs from Slug-R-US(30 cents ea) with various
50 cal slugs locked in tight, and shown with one out of
a factory load, the dark colored one. 50cal 385gr
Great Plains ML slugs lock in perfect for a lighter
loading. Other ML slugs will do and a few of
the Dixie Gunworks 50cal slugs lock in also...Ed

Re: 12GA From Hell

Some more slug setups and ideas.

First is USS brand sabot that European cartridge has, without
locked base, a discarding 12ga sabot, with .629" brass slug.
It is as accurate in rifled barrel as its locked on base
counterpart, in smooth barrels. Up to 750 gr brass slug
I tested. 3 shots in an inch, 30yds.
Shown with BPI powder cup seals.





2nd is the USS slugs with locked on base for comparison.
With corresponding length cases they were designed for.





3rd are heavy solid tungsten slugs, the smaller .580" cal and
1200gr, the bigger ones .660" cal and 2200 gr.
A guy in Southern MI made a few for me to check out. Now these
too hard to fire fullbore, damage rifling, must be in plastic.
These are just what the super heavy slug guys might like.





4th is a 1000gr 58cal tungsten slug in a 12ga REM style
58cal sabot. Notice how short it is for being super heavy.

Re: 12GA From Hell

Here is some more older cartridges and ideas.
First is a fellows collection of older brass cases.
They look like Berdan primed. Run from
36ga to 12ga, big one on right is flare cartridge.



Second is a paper case clad with
thin brass nearly to the top.



Third is picture of paper case crimped into
the side of a slug with shallow grooves.I did one
pictured above with a Dixie slug.



Some experimenting with 12ga discarding style sabot idea
that takes 58cal slugs/bullets.I pictured them above.
A fullbore,bore fitting sabot that takes 575-580 cal
slugs or bullets, cast or jacketed.

For reloaders to use, and not undersize ones
that have been available, for reloading guys. That
the guys haven't been able to get speed and accuracy
at the same time. These sabots are super accurate in
most tests, in factory Remington sabot loads. Much
more so than the undersize sabots reloaders have
had to work with.

I tested with the 440 gr .575cal hollowbase
Dixie Gunworks # BA-1103 lead slug and 3 shots from
heavy long barrel NEF nearly into same hole, at
30yds. Gun locked down. Going about 2200.
Our slow powder loads in 3.5" plastic.
Can be loaded faster.

No tests at long range, bad eyes/no scope, colder
than witches ---, and no time.
I am trying to find who makes these.There are
about 2000 injection mold companies in US



hubel458

22/02/12 06:50 PM
Re: 12GA From Hell

Another 12ga sabot idea, first picture is a 570 gr USS slug,
with Powder Cup seal from BPI, locked to USS discarding sabot
section. This shortens column so that we can get more of the
slower powders in we use, in shorter 2.75" cases. With slower
powders, they get to peak pressure a little easier
so that the cushion usually between seal and sabot/slugs
isn't needed. This locked on seal will aid in smoothbore
accuracy and it will work of course in rifled barrels.
This sabot has a peg on the back that locks it in original
setup to the green USS cushion base/seal, and we just pried
it apart and drilled tight hole to match in the Powder Cup
seal, and forced it on for a locked fit..
Slug is .629" diameter.



Next picture is 3 sizes of first USS sabot slugs, with
the locked on bases which work good with them. Giving
nearly rifle accurracy in smooth bores.



Here is old time picture of couple of Rodda 4 bores.
Man what nice old guns.



Next picture is a 1.5" Minie ball slug, might work for
close to a one gauge. It is next to older 37mm case which
might fire it also. Maybe a way to make a one gauge of
sorts, if.......I get enough ambition...Ed

Re: 12GA From Hell

yes - .35 Rem with 200gr. Scalloped Jacket RN.

We shoot a cannon with a sleeved 1-1/2" bore. We shoot 1.4" cast & patched WW balls from it, actually won the cannon shoot with it.

I cannot envision trying to stop that heavy cannon from rolling back when we fire it, let alone shooting something like that from the shoulder. Of course, the cannon weighs well over 500 pounds - and we don't cheap out on the powder.

I assume the 2"(50mm) ball is at least a 2 pounder or maybe 2 1/2 pounder, since a 1 pound is 1.67".

Re: 12GA From Hell

Yes I got the picture off of here, That slug gave me the potential idea
of a 1 bore using cut off at the shoulder surplus 30mm cases, if I get ambition.
Probably stop at the 2 bore.

Some more 12ga sabot work. The sabots in first picture are
like ones we want to get made for reloading.
They have 440gr Dixie Gunworks muzzleloading minie slug.
I related earlier that 3 shots with these in heavy rifled
barrel NEF got them all in nearly the same hole, at 30 yds.
Also 4 shots same distance, a 3 inch best group, smooth barrel.
The slight hollow base helps with smooth barrel. The hollow
base isn't as deep say as a 12ga foster slug.Another one they
have, a little heavier, with little deeper hollow base should
make tighter group. Loads in 3.5" plastic going about 2200.



Second picture shows something new I found out.It shows two
different wad setups. When I took the REM Accutip loads apart
I notice they used a thick seal, old style white felt cushion.
All the tests I read about that factory load, says it is always
near the top in accuracy. I had used the BPGS and flexseal
cushion mostly, as it seals real good. But in the smoothbore
test above the thick seal and felt wad gave the 3" group and
the other wad setup 5". The smoothbore, which isn't a perfect
system, for slugs not designed for smooth, worked out to show
and magnify difference between the two wad setups..

What first clued me in on this, to make a check, was recent
weeks research on net,on all sabot patents, where I read that
sometimes plastic cushions cock a little affecting accuracy.
That is the plastic cushions with a lot of space in them.
Where the felt/fiber cushions stay much more stable for a bigger
percentage of shots.The very accurate Hornady SST sabot has no
cushion at all between seal and sabot, but a thin rubber cushion
disc inside their sabot, and the above may be one reason.
The Federal Fusion sabots and the Federal Expander sabot
both are accurate--they don't have a wide open plastic cushion.



Third picture is of a Greener Martini slug gun a guy rigged up
with a heavy rifled bull barrel in 12ga. Great looking gun.

around the net. We are very happy with the response and help

Re: 12GA From Hell

Well, we surely appreciate this thread here, Ed. It really provokes thinking and ideas about the slugs and what can be done to help with accuracy.

It's also a big eye-opener on the slower burning powder use in our shotguns, rifled and smooth, with slugs or balls.


I'm not surprised over the tilting or collapsing of the long cushion wads, Some, by design, of course, would be worse at this than others. I've usually only loaded with harder wad columns, built up without cushions.

Re: 12GA From Hell

If the longer plastic cushions collapse straight they
are just as good as older fiber ones, but they go
crooked part of the time it seems.I have federal one piece
hard plastic seal and cushion here, they use under their
sabot loads, that the cushion part is real short in the middle
of it and it crushes straight all the time.Doesn't cushion much.
But you know all they got to do is use slower shotgun powders,
and extreme or no cushioning isn't needed. It is like the
tall shotwads with seal attached to bottom, for steel shot,
that are not cushioned, they just use slower powders.
Like longshot, alliant steel, blue dot, etc. Ed

Re: 12GA From Hell

Some possibilities with the 12ga sabots we have been
looking at. We may have possible leads on companies that
can make sabots, that have most of equipment to do so.
If they work out ok, the startup cost isn't as
high as others who have to set up complete machines.
We are working to line up a dealer who will get good ones
made, at one of these sabot making companies.WE hope to
have similiar design as the ones pictured below
but with slightly thicker base. I've sent these sabots
with Dixie cast slugs to different companies to show
what is needed, and what the full size specs should be.
With Dixie cast in they are similiar to Federal
Fusion sabots with lead slugs, only our slugs are 58cal.
We will keep you informed on what happens. At least 5
58cal slugs that Dixie has, looks maybe to work in these,
as best I can tell. And there are a few molds for
58cal cast slugs, by different companies.
The possibilities are, to reload with decent price slugs
and simple inexpensive sabot like these, for buck a round.
40-60 cent slug, 15-20 cent sabot, powder/primer 30 cents.



Those sabots I pictured above we been testing, had 385gr
Remington plastic nose bullets. I used some in my
585HE and I get them to 3900 fps. Just to see how
fast was possible in the 585. If I shot them in
my biggest 585, the 585 HSM, they'd go about 4500 or so.
They are real light compared to 750gr 585 cal bullets.
Like a varmint round. Do up a coyote fine.All skinned.



Some neat guns-First is a 20ga smooth bore Beretta style
break action 20ga. This is one of the greatest style
break actions there is. Beretta made their trap guns on
actions like this and great value for no more
than they cost. This one only 100 bucks.
We lengthened chamber to 3.5" so it can
use various 20ga smoothbore slug loads that we are
working on and testing..The SPW, Hastings, Lightfield
type 20ga slugs have decent 50yd accuracy in heavier
smooth barrels.



Next is couple of older guns I found pictures of,
a 4bore Hughes and a 600NE Wilke. I like them.
2nd is special 20ga double that poster Nitro 450 Express
HERE on the NitroExpress forum had built. Great job
on nice looking slug gun.Ed

Re: 12GA From Hell

The sabots we are working with, take about 15 different
58cal cast slugs for good fit, with the OD measurement of
sabot at.733" with all of them in. There are 4 Dixie
Gunworks MZ slugs, 6 slugs from Lyman moulds I know of.
Five slugs from Lee moulds.These are mainly muzzleloading
slugs and can be cast varying hardnesses.

Examples-58cal (.575"- .578")
Lee molds for 500gr, 460 gr, 350gr, etc, slugs
Dixie Gunworks slugs of 440gr, 375gr, 490gr, etc, weights.
Lyman 530gr, 510 gr, 460gr, 400gr, 315gr, etc.
And they are all good slugs at a saving especially
when folks cast their own.

I'm getting out info on these to see if any reloading
suppliers will try to get some made, so we will have a
quality, proper OD size sabot, to reload with.



Some stuff about sabots. I get questions about how
to reload them for accurate fast loads in plastic cases
for regular hunting and target use. Have to tell them we need
to have proper OD size sabot.. Most want sabot loads and not
fullbore cast....Why, they want lighter for less recoil in
regular weight guns, they figure smaller slugs cheaper,
they won't have leading with sabots if using cast, don't
have to lube and don't need gas checks if cast, cast slugs
for sabot use cheaper than jacketed. These parameters cover
a lot of shotgun only deer hunters trying to afford doing
their own loads, trying to be as accurate as expensive
factory sabot stuff and hoping the savings will allow much
more shooting.In the 1st is 440gr 58cal Dixie, and second,
one I like better a 510gr from Lyman mould. Third slug from
a Lee 460gr 58cal mould. 4th is various 58cal slug ideas.



Here is picture of a nice Armi San Marco 20ga break action
we found, that we're testing loads in. I really like
the style of this gun. I'm going to have extra barrel setup,
an extra heavy 585cal barrel and put my long 585HE in it,
to go along the other 585HE single shots 585HEs we have
setup on NEFs, and CBCs.



Here is a picture of nice Greener Martini 12ga, with new stock,
and a heavy rifled bull barrel, a fellow redid.
Such great work. And very accurate. All these guns need like
all singleshots, including break actions, are heavy barrels
and they shoot great and are easy to shoot with the
extra weight.

Here are a couple high speed, stop frame photos, showing how well
and even these sabots we want to get made, open up.
The petals being thinner with 58 cal bullets or slugs, opens easy.
The slots between petals, going into the base aids even opening.
We know a couple retailers that are interested in selling these
style of sabots, if they round up the money to get the
aquipment setup. Shooting supply companies are down some
due the economy.

And the action is long enough to make a single stack mag, if we
want, that would feed, with a little work, our 585 HE long case.



4th & 5th; pictures are of a old time 20 gauge, double slug and shot
gun that was priced little less than the big name English ones.
It is a Husqvarna double. Nice gun, we'd really have fun with modern
20ga slug shooting using this ..Ed

Re: 12GA From Hell

I have one of those Husky's, but the left barrel is rifled- straight. It is .705" groove to groove, so a tight 13 bore, while it is chambered for the 16 bore brass case.
The serial # puts it made around 1900. Husky data shows the smooth bore, a 16 bore, is meant for paper cases with shot from it's modified choke, while the rifled barrel is meant for a brass case with round ball and black powder load.

It shoots to the sights with 3 drams of 2f BP, filler wads and a patched .662" or naked .684" naked ball. The cloth patched balls are more accurate from the straight rifling and due to the lubricated patch, there is no fouling buildup shot to shot.

Re: 12GA From Hell

Some info we have found out about the operation of discarding sabots.
In first picture you see thin white line between the strong powder
and the sabot. It is the white fiber cushion wad pressed flat. It is
shown on the left in second picture. In the picture of it compressed
you see it is pushing squarely on the sabot. This is most important
wheh the sabot and slug exit barrel to get the slug started as
straight as possible for accuracy.

Other types of plastic cushions aid in sealing and help get best
velocities but the rolls and legs in them can allow them to side shift
which can affect how straight the sabot is on exit, thus causing the
slug to deviate. The gray sabots we tried had cushion on the bottom
of them and inspecting them after firing you could see they were pushed
sideway some of the time. That is why we are trying to get tight
fitting simple sabots built and recommend using heavy plastic seals
with fiber wads to have least deviation and best accuracy.







Third picture is our steel block we are using for 2bore
with breach hole we got EDM'd into it.



Fourth picture is an old time Kynoch round called the
"Lethal" and the "destructor".




Fith picture is a H&H underlever double 8bore.
Nice beautifal old gun.Ed

Re: 12GA From Hell

I think we found good overall sabot design that will
be the easiest to get made, easiest to get seals
and whatever wads needed... Keeping design simple.
It is same simple design as the ones pictured above
but with slightly thicker base.It is fairly compact
for more room for our slow powder loads, and when
using slower powders, we don't need as much cushioning
which makes the room for the powder. Larger charges
of slower powder, better velocity with less case
expansion, and more reloads possible.

We hadn't tested soft lead 58cal slugs in 12ga sabots
for penetration until now.. They did very well,
two different 440 gr ones, going though 4 inch dried
timber, pushing out some wood on the back.
Shows they are just starting to expand.Should do great
for deer and hogs. Going 2200 in long barrel NEF.
Have pictures later. A 58cal slug at good speed is
nothing to look down on. Many African hunters liked
that caliber in their 577 doubles for big game.
Slugs can be loaded faster, cast heavier,
and cast harder for any need.And compared to other
way of getting slugs out of a shotgun, once
we have good fullbore sabots, we save on needing
bullet lube, gas checks, cheaper to get, no barrel
leading, much better BC in the same weight of slugs
compared to short fullbore ones....


Here are pictures of molds that can make cast
58cal slugs for the 12ga sabot we are working
on.There are many makers and brands and styles
of molds and weights available.






Here is picture of a 10ga wadcup with a 730gr hollowbase
lead slug in on the left .In my heavy barrel 10ga smoothbore
I got 6" group at 50 yds. If we made hollow in the base
bigger it would be more accurate in smooth barrel.
The slug is .69cal one,measures .686"(from Lymam mold
like in picture), that Dixie Gunworks has. I bumped up the
diameter about .015" --wadcup is BPI VP100.




Here is picture of a nice 8ga double a fellow has.
Great looking gun..Ed

Re: 12GA From Hell

You can easily increase the weight fo the .58 minnies by turning the plunger down and shortening the hole it makes in the end of the minnie bullet - all the way to solid is expansino isn't needed, or it fits well in a .58 bore. With heavier charges or the faster burning powders & if of pure lead, the solid .58's will slug up to fill the grooves (if any) of the barrel. Also, since they fit the sabot in that situation, they do not obtruate and get out of balance as could happen with thin skirts.

Re: 12GA From Hell

Working more with 58cal lead slugs in 12ga sabot we want
to get built. We shot a few for checking penetration,
with 440gr slugs at 2200 plus fps. Shooting into popple.
In picture the 6x6 on the left penetrated by harder lead
alloy slug, with slug showing very little expansion on
exit from the 6x6, On the right, soft pure lead slug through
a 4x6 starting to show expansion on exit. These slugs can be
gotten or cast your own to about any hardess needed.
They can even be heat treated to be as hard as jacketed.
I have rounded up 9 different ones very easy, shown in
2nd picture and there are more. Ones in picture range
from 400gr to 530 gr. There are molds to make them
down to 350 gr and less.





Here is picture, on left of Accutip sabot we been taking out
of loaded rounds and testing 58cal lead slugs with,
and right a hard plastic sabot model, we are working on
to see how slugs fit and how it looks, and how
it compares to the Accutip and other sabots we have
here from WIN, REM, FED, Hornady.



In picture is a really neat, very strong, 10ga Beretta style
gun we got. Its barrel is heavier at the muzzle than most
all 10 gauges we've seen except the NEF with bull barrel.
Made by Pedretti, has top lever to open, instead bottom
lever like Beretta or the Investarm 20ga we showed above.
Going to make into switch barrel for 10ga and monoblock one
in 585HE later. Have 2 barrels for it. Has nice big pad we put
on it and it is weighted to 12 lbs in 10ga..



Now for some internal ballistics comparisons.There is formula
for figuring appoximate Average Barrel Pressure,

You take Muzzle Energy times 12......and divide it by

the BORE Area in sq in, times the length of the barrel in inches.

Examples- you have a 458 WIN, my 585HE and 12ga 3.5"--
all at 5000 Ft Lbs of energy which for 458 be standard load.
The 585HE in this mode would be burning close to charcoal.
The 12ga 3.5 would be 440gr slug in sabot at 2200 plus.

The 458 Ave Barrel Pressure is about 16,000 psi.
The 585HE Ave Barrel Pressure is about 8,000 psi.
The 3.5 12ga Ave Barrel Pressure about 5,200 psi.

The purpose of this-- To show the possibilites of big bores.
Ok you can't go much higher with 458WIN, about 80gr of powder

But 585HE you can get way over 10,000 ft lbs,with 180gr powder
it holds running at 458WIN Ave Barrel pressure.

AND 12ga and 3.5" brass case in Savage 210, slow powder loads,
heavy barrel, you can get over 10,000 ft lb. with 180gr powder
at much less than 458Win Ave Barrel Pressure.
Possibilities are really great fun. Ed

Re: 12GA From Hell

Some 12ga sabot progress. Here is pic of our sabot model, two
in front, shown with Accutip sabot behind. They are all holding
58cal slugs, showing how tight they fit and conform
to the inside of the sabot petals. A decent fit is a help
for better accuracy. Hope they get built for us this summer.
We are working on it.




Second picture is from a fellow who put 58cal cast slugs in a
thinwall 20ga shotcup and shot this at 50 yds. This with first
load he tried. Great accuracy for so many shots. This shows
great possibilities with 58cal slugs, and should even do better
in the 12ga sabot like the above we like. I've heard about BP
guys who got into 58cal that they get good accuracy.




Here is picture of some the grey bls sabots showing the way
they have got bent and beat up, and shows what I and many
others have found; that plastic cushions can bend and twist
and shift, affecting the slug on leaving the barrel, affecting
the accuracy.




On a future work, I'm doing a Greener Martini in my 585HE long
case, Here is picture of a parts action with a stock idea
I'm experimenting with. Might use this or regular pistol grip.

Re: 12GA From Hell

Back after losing time to a lightning fried computer.

Test in 3.5" plastic using a few accutip 12ga sabots out of factory loads.
The 12ga accutip sabot, hard cast 440gr 58cal minie slug in
36" rifled NEF at 2200, and it went through 12 inches of wood like
butter. The hole out showed it was starting to expand a little.

Test of softer lead 500gr 58cal Minie with deeper hollowbase in accutip
in smooth cylinder bore barrel at 2000, and 3 shots in 3" at 30 yds.
This was a Lyman 575213 new style minie slug
More experimenting can make these work fair in smooth barrels.
For best accuracy use a blunt nose heavier 58cal 600gr slug with
deepest hollow in the base. The blunt nose would be more front end
heavy and a little more accurate from smooth bore..
Lee and Lyman have molds like that.Others selling slugs also.

I mentioned before about seals/wads must be stable and not crush
down off center, or it might affect accuracy. Here is picture of
the one piece seal and wad Federal uses in their sabot loads.
Notice it doesn't have a lot of space in the cushion part that would
allow it to tip or go off center.



Here is picture of some 10ga work using expanded 69cal minie and
700cal bullets in 10ga wadcup. 69cal hollowbase fairly accurate to
50yds in heavy barrel smoothbore.



Here is picture of the Savage 110 done in my 585HE. Hollow butt of the
stock is weighted, gun handles nice.Ed

With an other scoped NEF Ultra 12ga, 24 inch
barrel, shot hard cast, 400 gr 58cal Lyman Minie
in Accutip sabot at 75 yds. Hit small paper plate
5 for 5. Going 2000fps.

Speaking of 585HE above. We have two in falling blocks,
10 bolt guns,5 break actions, and other types.
A fun cartridge, and now that we are working with
58cal slugs in 12ga sabots, 58 cal is where it is at..
And now we are getting a run of 585HE cases made.
Bertram getting ready to make the last die;
done later this month and will be doing cases then.
Cases are 3 bucks each, bulk shipping included.
He usually charges 5 or more for wildcats, but as
I'm furnishing final sizing die, and he will ship
by bulk freight saving him handling, and he had
a couple tools already to use, he said $3 each, a
real good deal..

He will ship whole bulk order to me.
I will pass them on to everyone buying in first run.
I'll will get a bunch also, to load for others,
to fill orders, and collectors. Get 100 for 300 bucks,
or be a 500 guy buying a 167 cases for 500 bucks.
I'm having guys just make out MO to Bertram Bullets
and get it to me and I send them on to him.
I'll keep track of who gets what and ship cases to
the guys helping with first run, no shipping charge.
Want to make the run as big as possible. Got
money ready to go for over 700.
Like to get 3-4 times as many made if possible.Ed

Re: 12GA From Hell

Sorry, late in posting, bad weather, computer lines zapped again.
Can't find time to work on 2bore yet.Haven't got barrel drilled yet.

Some more experimenting with the Accutip sabots, Designed a
two ball load using .577" cast lead balls. Bottom ball flattened a
little in vise with the flats up and down in sabot.
Used a fold crimp, 3.5" once fired REM case in NEF, long rifled
barrel.....Fold crimp goes down on the top ball...Round
balls 285gr each, going about 190 hit within 2 inches at 30 yds.

Those 58 cal inside Accutip sabots are really versatile.
Tested 3 shots with 58cal Buffalo hollowpoint, hollowbase, lead,
muzzleloading slugs, 2" at 30yds. All loads with plastic x12x
seal and white felt cushion under sabot.

Experimenting with an Enfield, had one set up with my 700HE 3.25,
and just did one in my longer 700HE. Did little longer port and
added little more weight.First picture. 2nd picture is a neat 3 barrel
16ga, which if I had it,deepen chamber, I'd have a neat 16ga FH....Ed





PS---We are gaining on getting the big run of brass made for our 585HE.
He is finishing the tooling and soon be producing. We want make the run
as big as possible so everyone is welcome to help. You in US get in on
first order, cases are $3 each.Those in the US he'll send whole order to
me bulk freight, a big savings, and I'll get them to the parties involved,
no charge for helping out on first run.The $3 cost is a great bargain
compared to other big bore cases and if you buy 150 or so you've saved
enough, over the cost of others to buy a barrel to make 585HE gun with.
My contact--- gunowner at journey.com

For those in Australia,Canada,South Africa,UK, and other countries
send pmt to Bertram and he'll send cases to you individually when done.
Right now can't afford export costs to send cases back out of US...

Re: 12GA From Hell

For you folks in Australia, Bertram is
getting ready to make the run of my 585HE
cases. Would there be a bunch of you
interested in a group buy, of the cases
right direct from him. If so, no time like now,
and he will be able to make more runs later,
whenever needed, as the production of my
cases works along with continuing orders
of another cartridge he has to make every
month or two.. I can't ship economically to you
from US, when you there can get from him
for 3 bucks US each. And Manson Reamers
here in US can supply reamers, CH4D in US
has the die sets. It is perfect case for
bolt guns and falling blocks, and I even have
it in break actions. A light load is 750 gr
at 22-2300, and any action a 505 Gibbs
fits into will do 585HE. And I have loads all
tested, developed. I plan on using the rest
of my days making this case the best and
most used 577/585 big bore. I'm also posting this
message for African and Canadian shooters.

Re: 12GA From Hell

Here is picture of the two ball sabot load, using two
58cal balls in a 12ga Accutip style sabot.



Hoping we will have sabot like above for reloading soon,
in volumn so we can load and test a bunch of these 58cal
bullets and slugs. There are soft cast, hard cast, and
the heavier jacketed. These all work in my 585HE also.
The 440gr hollowbase ones loose in the big box on left
measure in at .585" and work great in my 585HE cases.



Part of my 585HEs are smooth barrels guns
just for testing the different style guns, and different loads.
In the one smooth barreled one I have on BBK action, shooting
my 585HE with 440 gr hollowbased Minie slug, we were hitting
8 inch paper plate with them going about 2700 at 30yds.
Hollowbased they act like shotgun slug at short ranges.

Will be neat deal to shoot them in 12ga accutip style sabots in
rifled 12 gauges and the smoothbore 585HEs with $30 barrels.
Here is picture of Pedretti(Beretta style) that came as 10ga. I
have monoblocked in 585 barrel. In picture there is 585HE case
partly out of chamber. I have extra fairly heavy 10ga barrel
also and changes in 2 minutes. And that monoblock break
action locks up like a bank vault.Real strong.

We also got first part of funds collected for the initial big run
for our 585HE long cases being made. Sending in bunch
this week, and need more to make run bigger For more info
if your interested contact me.

We, others, and 'VdoMemorie' on the Cast Bullet forums
and Shotgun World are experimenting with 58cal Minie slugs and
58cal round balls in 20ga wadcups, and find it is away to slug
load your 20ga economically. You can use 20ga Commander wad and
also shorter "sporting 20 short" wad from BPI. I cut bottom off of
commander and use felt wads and 20ga obturator seal with .575"
470gr minie slug and got 4" group at 30 yds, with smooth barrel.
That is with heavy thick,smooth barrel I put in CBC below.

Here is picture of the CBC break action that I mono-blocked in smooth
super heavy, thick 20ga barrel..30" long, chambered for 3.5" cases.
Works great with 3.5" plastic or brass cases.



Here is picture of the 1887 WIn with my 585HE in it. I put in a
heavy barrel and different kind of extractor Barrel is 28"..
I like putting my 585HE in all the old style of guns, just
to show all the uses the case has.



I found supply of super long bmg cases to make my 700HE Long cases.
It is 4.27" long and holds over 370 gr ball powder, 1000gr at 3400 plus.

Re: 12GA From Hell

Good news, We got a few samples from the first production run of 585HE
cases from Bertram, to test for strength and measure for uniformity.
They all measure perfect and especially the belt length headspace,
which was all within the .270" length minus .004".specs I asked for.

He made part of run, about a 1000 without headstamp..And over 3000
with headstamp. Over 4000 total. Cases only 3 bucks each,
if you get in on the first bulk shipment right away..Still time
before he ships.I want as many bulk freight shipped as we can.
Got money in for about 1000 so far. The few he shipped by mail to test,
cost $1.50 postage each, so that is why we want to get the numbers in the
much cheaper bulk freight order as big as possible.Folks in
AUS order direct from him.

I tested some moderate loads(650gr @ 2400) in NEF, CBC, Pedretti
break actions and didn't need sizing on the bottom 2/3. Cases fell out.
Real tough built cases, Fired couple 650gr at 3000 in Enfield and extracted
ok, and resized ok back down to specs.About a 62k psi load. Pockets tight.

He supplies same base cases for 408 Cheytac, used with hot military sniper loads
that run real high average pressures.So maybe we have a winner.He will be making
these Cheytac case runs regular so we can get our cases made anytime
we get money built up for a run.Here are pictures.

First is old on left and new on the right sectioned,
showing how heavy built the new cases are, as well as
Cheytacs he makes that has same base inside.Our 585
is belted and he uses different header, than for the
Cheytac/Gibbs bases one which uses a header
with no belt.



Second is top view of cases new and old. On the left is
4 new ones that come with no headstamp that I stamped,
and the 6 new ones in the middle has a 585 stamp.
He made a 1000 without headstamp and over 3000 with stamp.

Third side view with some in # 31 holders.No special
holders needed. Notice how uniform belts are.

4th is one with AP bore rider bullet in with others
behind. Maybe have a military use, saving brass and
use smaller actions than bmg and 14.5 Russ.
With about the same power as a bmg. Ed

Re: 12GA From Hell

Ed,

Ripp's thread on Montana Rifle Company got me to notice the low price of the big 505Gibbs PH rifle. Wow! Just over $2k for a Gibbs. Beats CZ by almost a grand.

Have you considered working with Montana Rifle Company to get some version of the 585 offered in that $2K safari rifle? I know you gave them a lot of support during the times many on that other forum were complaining about the slow development time for the PH action. A nasty crowd over there. Well the action is done. Now a very reasonably price complete rifle built around that action. It would be nice to have a source of loaded ammo. Superior? I would assume from a manufacturing point of view you would want the rim exactly to 505 specs. I like the 3" case version, but; I am certain that a 3.25 chamber would not hurt anything and be more flexible. I would be nice if there was offering a practical hunting load like 750gr @2100 fps, in addition to a bragging rights (12,000? ft-lb)load. A level I and II choice.

The trick really would be for Montana to agree to chamber any version of your 585 for ~$2K in a no frill package. Ammo availability might promote sales.

I have to agree a bbl band seems almost mandatory these days. Even low cost Ruger 375's went that route with a little complaining. You might pass that along if you have an opportunity.

Re: 12GA From Hell

In our research to find economical and easy to use setups to load
various slug/sabot combos in 12, 20 and other gauges, you've
seen what we are doing with 58cal slugs in 12ga accutip type sabot we
are getting built, and 58cal slugs in 20ga BPI Commander shotwad.
You've seen pics of group shot by Ajay 58cal in 20ga Commander wad.
And Greg Sappington made 16ga HP slug that fit 12ga BPI CSD wad.
CSD wads are little thicker. In that vein we found another 20 ga combo
that uses the BPI 20ga CSD wads and larger diameter of the 54cal
muzzleloading slugs. Wad is thick and short so we can get the
volumne of our slow powder we want in the loads for higher speeds.
And base of CSD 20ga wad is thicker and stronger than most wads.
. It doesn't have built on cushion, doesn't need cushion, which is not
needed for slow powder loads. Has a good built on powder seal.
It is long so it can be cut to fit any 54cal slug length.
Best 54cal slugs to use are .543" and up.
There is .548" Sharps style 2nd in picture from Dixie Gunworks.There is
54cal Great Plains in picture on left, Far right in picture is 550 Magnum
jacketed bullets in 20ga CSD. Great for hogs, bear. There are a variety
of 54cal slugs you can cast or buy. Not big number like 58cal, but enough
to find good simple combo. Shot 3" group with 54cal Great Plains in
CSD at 30 yds, smooth bore. 380gr going over 2000 fps.
Second picture shows they even work and fit good in 20ga RMC brass.
Fits in a brass case real tight with .548" Sharps style slug in picture..





Third picture shows how we mono-block 585HE barrels into strong
singleshot break actions. Done it in NEFs, CBCs, Pedretti, Beretta,
and the Magtech 199 shown above.



Fourth picture is the O/U Tristar with 585HE on top and 3.5" 12ga bottom.
We sleeved the top barrel with .585" ID sleeve. We will use it with
the 58cal .585" Minie hollowbase slugs. Bottom just for shot loads
with a interchangeable chokes. Ed

Re: 12GA From Hell

Little work on non-discarding 12ga sabots,You can get SPW
wads without slugs in them and we set up one for a light load.
We put a 20ga Lyman in some and they stay together ok. Just
shorten the bottom skirt of Lyman and bevel the bottom corner.
Total weight sabot and all is 360gr,,Shown In the picture..
We also shrunk the skirt of the 12ga Lyman cast slug and put it
in 12ga SPW wads and total about 550gr. If you have Lyman
12ga mold, can use it as pattern to make a slug to go into a
SPW wad. Leave the top part same as original Lyman and make
bottom so it fits in the SPW with real tight fit.



I like to use P14/M17 Enfields for our testing. Great for my 585HE
case and in picture it shows how we change the sear spring to one
on the back of the sear. So we can open up the bottom to feed
the long cases from singlestack magazine box by removing the
unneeded front of the sear and the action metal above, giving
room to the back for cases that are 3.9" overall loaded length.



Couple guys who are setting up 585HEs in singleshots are going
to shoot 58cal Minies and other bullets and use black powder
and/or substitutes. So I tested some with Pyrodex pellets,
Used 54cal, 60gr equivalent and they stack in the case ok,
and just beveled corner of bottom one so it set tight to the base.
As the case has good inside radius. Used 3 pellets with 24ga
card over pellets, 3/8" felt wad and another card with 440gr Minie.
There is a certain nostalgia about all that sulfur smell.If you can
stand the cleaning. Slug going 2100.. 4 pellets about 2400.

Here is picture of another long bullet in sabot/wad , in 12ga that
was sent to me. Ajay on Shotgun World set this one up



Did some testing, 12ga plastic & brass with new super slow RE-33 powder.
It fires off ok in 12ga with 700gr and heavier slugs, with shotgun primers
like slow RE-17 . It is made the same way as RE-17 as far as how the
deterrent is put into the powder. Which is why it ignites in large diameter
cases like 12ga and BMG with shotgun primers. Really be great for super
heavy 1100 to 1500 grain slugs to get good speed and keep case damaging
peak pressurs down. Example in 3.5" Fiocchi 12ga plastic case, 690gr slug in
BPI Helix Driver Wad with 180 gr RE33 the basecup only expanded .002".
And the Fiocchis are the softest bases around.Ed

Re: 12GA From Hell

Last picture above shows what can be with sabots. It was thought to
be 20ga size when we got picture, but it is a smaller
45cal caliber sabot with 30cal streamlined bullets in them.
This was set up by the poster 'edge' on Castbullets forum.

More info on the SPW sabots with 520 gr Lyman reworked and locked into
them. With 3.5" brass RMC in the NEF long barrel gun, going about 2500
they smash though 6" timber with Lyman tearing wood up. Also got the same
combo 2200 in 3.5" plastic. Lyman in sabot on the left in picture on
right is factory SPW.



Another setup using the largest diameter 58 Minie I have is this .590" in this
12ga real thick muzzleloading wadcup for steel shot. I chamferred the bottom of
Minie slug and wedged it in the cup. The cup comes real long and we cut it off.
That leaves perfect edge to roll crimp against. Dab of epoxy holds the Minie slug
in, so it works like a non-discarding sabot. This wad has is own seal and fairly
short compared to others, so it leaves room for more of our slower powders.
Shorter slug and wad setups make loading easier.





Here is picture of the Magtech we redid in the 585HE by mono-blocking in 585
barrel. This is second one we've done. Tried out a ladder peep sight on the
back. Makes a neat gun.That underlever is a great touch.Ed




As part of the 585 test guns have smooth barrels, they are like a hopped up
24ga. We got couple bags of 24ga cards and felt wads. Easy way to use
reduced loads as the wads are perfect in 585 case. For comparison top load
say with RE17 and 650gr bullet is 170gr, but you can put in 100gr and card
and couple wads and have real easy load. And you don't have to worry about
airspace. Great for reduced loads with Minie slugs. In the same vein you
can put in a card over the powder and about 3/4 oz of shot and have a real
speedy 24ga shot load equivalent. Put card over the shot and glue it in.Ed

Re: 12GA From Hell

First picture is of nice finished 87 Winchester Will Sanders got set up
and he is using short brass cases.Beautiful scroll work on the stock.



Next is takeoff of a slug idea from Longbow on Cast Boolits, 12ga lead
roundball with section of copper tube, with wads inside, bpgs seal on the
bottom, screwed together. I have many boxes of wads. Now he did his with
screw into ball, put tube on with screw centered inside tube and filled tube
with hot glue. It stays together. Both are nose heavy for smooth bore work.



Next is side sectioned view, one of our 585HE cases, showing how 3/4
ounce of shot fits in.. 585 is same bore as 24ga. Cards shown are 24ga.
Just glue top card in.Some of our 585s are smoothbore and the HB Minie
slugs work at short range and the shot will do at short range also going
over 2000 fps. Could use 24ga shotcup.



Next is a Mossy 390 with heavy 585 barrel. Makes a nice big bore gun,
and handles nice with texturized stock finish. About same strength as
the heavy break actions I have 585HE in.Ed

the best loads with short brass RMC cases. He had it worked on to

Re: 12GA From Hell



With a 12 bore ball weighing 583gr. (.730" - pure) along with the copper tubing, probably .032" wall along with the steel screw, the weight would be over 600gr. - no slouch and an excellent idea.

I've a feeling I should try this in the rifled Mossberg pump. If a person could find some 5/8" ID pipe, it should run about 11/16" (687") OD. With a wad centered, tube filled and screwed tightly to the ball, the base wad would obturate to seal the powder gasses behind it and take the rifling as would a groove diameter ball (.724" in my 12 bore Mossberg), thus should shoot quite well. Length could be adjusted for best accuracy in whatever twist happens to be in the gun - ie: 35" or whatever you have. The copper tubing (or aluminum - some comes in standard ID measurements, while most copper is outside diameter) would not ride on the rifling at all, kind of a wasp waist bullet, reducing pressure and allowing higher velocities, if deemed necessary.
It is amazing what and how deeply a hardened 12 bore ball will actually penetrate if driven 1,500fps or faster.
According to Samuel Baker, through and through an elephant's head, ie: 'exit'. Sounds deep enough to me.

Thanks for this thread, Ed - MUCH food for thought with most of the thought already spelled out and tested.

I love the Greener and I have my 585HE in one, but
I wish they were bigger with thicker sides,
for real big stuff.

Well you can set up inexpensive in other guns.Go smoothbore
and experiment and get some 50-70yd accurate smoothbore
10ga setups with the BPI VP100 wadcups and hollowbase
69cal Minie bullets. And then get the heavy bull barrel NEF
10ga goose gun, the newer SB2 models.The long barrel is
best with hairy loads They are alloy frame, heat treated strong
and will take our slow powder loads of about 2000 fps.Ed.

Re: 12GA From Hell

Here is picture of the 12ga short brass RMC cases being used in
the 1887 WIN shown above. They are 2 5/8" long cases and we
get 600gr over 1900. He had work done on action to get it to feed
these and 3" roll crimped plastic. Brass loaded about same length
as 3' plastic crimped little long.



Next pic are Lyman slugs cast for thin 12ga wad, used in thickwall
10ga VP100 wads. These Lymans I got are on large size and fit
VP100 fairly well. Makes easy, lighter, superfast load in 10ga.



Next; further idea with Longbow's tube/roundball slug shown above.
Use tube hot glued to ball with screw in the back and use it in
a 10ga VP100 wadcup. These type slugs little more accurate used
in wads as opposed to fullbore.



Next shows picture of a long 585 bullets, about 1600gr in our 585HE
cases. Got the idea from Bret In Minn that could setup 585HE
guns with super long throat and load down to subsonic speeds to
make the 585HE Whisper.....And regular bullet loads would still fire
in the same guns......And at subsonic 1050fps it would have about
4000 ft lbs, about twice what the peashooter whisper cases have.
And my case could get a 2400 gr long bullet to same subsonic speed
for 6000 ft lbs. And one that long would have proportions like the
newer tank cannon, smooth barrel saboted darts, that it could be
possibly be done, using long 2400gr in smooth barrel.
Neat ideas from guys interested in whisper type loads.



Last is picture of FBW in our 585HE with handgrip stock and light
barrel for lightweight carrying. Grip is weighted, gun is 6lbs.
Barrel is 28". I'm not a fan of light barrels. 650gr at 2500 is max of
what I can hold onto shooting from the hip Moderate load
.Little info about my 585 loads, like in the break actions and the
Mossy in post above. I load about 85% max velocities, but to get
85% we only need 2/3 the peak pressure, like 40,000 psi
instead of 65,000...Ed

Re: 12GA From Hell

We have a winner it seems. The 12ga sabots using 58cal slugs.



The sample 12ga sabots got here earlier this week. And we got a bunch
of testing already for opening and sealing, and some accuracy testing .440gr
Minie bullet, measuring .575"; with OD of sabot with slug in it of .737" It is
perfect. Going moderate 1800. Petals opened perfect and evenly and they all
stayed on perfect. No petals twisted or torn. Tested in 3" case with slower
powder loads. 80gr of 4759 and 50gr Alliant Steel. Fiocchi case.
Savage 210 rifled barrel, 1 to 35 twist. Cases with slower powders expanded
only a little, and those cases are soft ones.
We have big bunch of the sabots here now.




All petals were opened at about 30 deg to the base when picked up.
With ither powder the bases have no damage, or burn throughs or melting.
Took rifling perfect, so skidding on the rifling. Most of the rifling grip is on the
bottom half of sabot, which is why these and Accutips are best as the bottom
is full size instead of dropping back in size, compared to the top, like many
other sabots. Rifling in the barrel still clean..



The Minies are hollow based and the slug edges did not cut into the inside of the
sabot bases,just a slight impression. We have got good base thickness.
Good Accuracy - In the cold and very windy day, hit milk jugs at 30 yds.
Here is picture inside sabot showing just a slight indent. No need of cards under
slugs, and if you did, the the slugs would set up in sabot and not have the
curve of the slug behind the inside circular rib for best fit...

You got to use right powders. With right slower powders( not fast shotgun),
that start easier and used in larger amounts, you won't tear up the sabots.
It is false economy to use all fast shotgun powders,trying to get twice as many
shots per pound... and tear up sabots, expand cases too much, get poor groups,
miss that deer or whatever. For most of you in 3" cases Alliant Steel is best.

Re: 12GA From Hell

Here is picture of a bunch of the sabots with different slugs and bullets.
Back Row- Two roundball load, balls 285gr each-- pointed long 700 gr -- a blunt
solid 700gr-- tungsten slug 1000gr --- jacketed bullet -- 600gr.
2nd row-611 Lyman 530gr Minie- 500gr flat base- Lee 500gr hard--Lee 500gr soft
1st Row- Lyman 440gr old style minie-- Lyman 510 gr new style-- 440gr from Dixie
Gunworks-- 400gr Lee target style. I like 440gr old style and 440 gr Dixie. For sale
on Gunbroker is all sizes and weights.. Or cast your own. Lots of moulds around.
Lee moulds only 20 bucks. Best diameters to use are .574 " to .577" Minies.
If you have ones bigger and they are not hardened you can roll them betweem two
hard surfaces and they will get little smaller. I have some that are .585" 440gr
and work in my 585HE and they can be rolled smaller.



Here are sabots with variety of seals/wads, and the shortest one in picture with
white felt wad just fits in 3" case with 80gr 4759, and still leaves room to roll crimp.
I compress it in hard. Now only faster powder than 4759 I'd use is Alliant Steel in
smaller amounts, 50gr Steel, in 3", and thicker wads and cushions like shown.
To roll crimp over the top edge of sabot we had .220" of case before crimping.
You only have to crimp top edge of sabot real good.




After crimping the slugs are tight and don't move around. The circular rib inside the
sabot holds slugs tight back into the base. Speeds over 2000 fps
will be gotten using 3.5" plastic cases, with our slower powder loads. .
More testing for accuracy yesterday, a warmer, calmer day, with steel sights.
Hit. paper plate at 50 yds.

As said above, best to use right powders. Right slower powders( not fast shotgun),
that get to peak pressure slower, thus can use larger amounts, can get to higher
velocities, and you won't tear up the sabots and won't expand cases as much.

For most of you in 2.75" and 3" cases Alliant Steel is best.
FOR 440GR SLUGS IN SABOT---For 2.75" start at 40gr and go up to about 50.
For 3" start at 45gr go up to about 55. I like 3.5" best as you can load much easier
for speed, still have more cushion wads. Start with 50gr Steel, go up to about 62.
Case brands act different, but using the slower powders minimizes the differences
and keeps us away from surprizing pressure problems.

In 3" plastic,most 4759 I can get in and still have 1/4"cushion is 80gr.... In the 3.5"
I can get in 105 gr with this sabot and get over 2000 fps, In these loads if using
480-500gr cut back 3 gr. These 58cal slugs can be cast or they are at Dixie Gunworks
and 4 guys on Gunbroker got them. Get ones .574" to .577"

Re: 12GA From Hell

Some more info about our sabots and various slug weights......
First and most important is our sabots fitting real tight like the Accutip
Sabots, they will not get the same speed at the same pressures as
the undersize grey and blue ones, But they do leave the barrel
headed straighter and without damage, even with hollowbase 58cal
slugs in them as the pics above show. No cards under slugs in sabots.,
But with good powder seals, using Alliant Steel, and good 1/4" minimum
cushion wads.

The 440gr Minie slug of .575" in the 3" cases is the one I used as a
base loading, to work each way by weight to find what loads of
Alliant Steel work and extract in my NEF. Using 3" soft base cases.
Here is pic of before/after of Fiocchi cases, on right unfired and left
fired, 55gr Steel with 440 gr slug.



For 440gr max of 55gr Steel
For 400gr max of 57gr Steel
For 360gr max of 59gr Steel

For 490gr max of 52gr Steel.
For 510gr max of 49gr Steel
For 540gr max of 47gr Steel.

I tested all these weights for extraction. It is real nice to reach into a
bucket, grap a sabot that fits right, and go to loading and shooting.
Many of you need to get in on the fun.
Here is picture of Fiocchi with sabot, roll crimped. The top of sabot is
perfect for roll crimping...It is setting under crimp tool in drill press.



Earler I showed the 585HE Falling block with pistol grip and the light
barrel. Here it is with Knoxx Compstock buttstock. We added 2 extra
springs inside for relatively hard recoiling gun, as stock originally made
for a REM 870 Pump. Works great and looks nice; will putting one on
the Magtech 585HE singleshot break action and got one in rifle stock
for Ruger 77 in 585HE.



And many guys want wildcats with shoulders, with big neck down, so
in developing the ultimate 700 blaster, here is the 700HSM. Shown next
to Gibbs 650gr ball powder..1000gr at 3800...How about that.

Re: 12GA From Hell

The sabots aren't moving fast at all and I got to
money back out of them right way, and seeing as how
we're low on slugs to send with the sabots, in big numbers,
and no one has yet to buy out our stash of sabots and
set up so they can be selling the sabots, so we will try
selling them fast a few weeks longer. So to get these
moving out and getting tested and we pay our bills,we will
be having sale on just the sabots, in larger amounts only.
We will send one each of 440gr and 500gr slug so
the guys can see what we have found that works.

Because of the shipping costs and boxes that 2, 3, or 4 bags
of sabots fit in, that has an affordable postage cost to pay,
we have to sell these in 200, 300, and 400 size orders..
So, 200 sabots $47 Shipping included,
300 sabots $65 Shipping included...400 for $83 shipping incl.

Now 200 of the other brand X of undersize ones cost $68
plus shipping. There was dozens of guys the last few
years all over the internet that bought undersize junk,
that wanted good sabots and complained that the ones
they bought elsewhere didn't work...... I haven't heard
from most of them, So guys please get around quick
and help us out here..MO, Check, Paypal..Ed

Re: 12GA From Hell

The sabots work in brass cases .First is sabot in a Magtech brass case,
next to 3" plastic.. In shorter brass it would hold about as much powder
as in longer plastic if loaded like in the picture..
Sabots are about .734-735" with slugs in them, and
the Magtech brass with its thin sides still is slightly small OD at the
top compared to plastic, with sabot wedged in.



Next is sabot in RMC case, and sides are full thickness like plastic cases
at the mouth, so don't expand case to hold sabot. We have RMC make case
mouth ID to fit sabot. Sabot being little over fits barrels tight and rifling
impresses into plastic well and gets best spin, and being tight it leaves barrel
straight, with petals opening evenly. Brass case mouths are tight enough that
we push sabot in with a press.Saves trying to crimp heavy RMC case.



Here is picture of a barrel and barrel on a gun from 20 gauge singlshots that
will have the heavy 20ga rifled barrel in picture, mono-blocked into them.

Re: 12GA From Hell

What causes sabot problems/inaccuracy. Some pictures will help.
First 2 shows a skinny post that pushes on a cushion or sabot
bottom and it can bend or deflect which if that way when exiting
barrel can start sabot or slug crooked.





And more important item that causes a lack of accuracy is if the
base of discarding sabot tapers or steps down so that it isn't real
tight as it leaves bore, which can allow it to be cocked.
On the left is our sabot which has base right and other brand
which tapers a bit. Easy to see.



Next is a ball and slug load in 2 of our sabots. A 285gr .575" ball
flattened, put in the bottom and a 400gr Minie above, two different
styles of Minies.



Here is couple 16ga discarding sabots I made from the undersize
12ga grey ones. Didn't have to take off much. Much better use
for them. I made them after Paul in Alaska asked about
where to find 16ga ones, to see what they looked like.
They still use 50cal slug.. Ed

Here is picture of 12ga wads showing good and bad support.



Here are 2 sabots on the right with super heavy tungsten slug. It is 1100gr,
but tungsten costs ten times what lead costs.



Here is a sabot home defense or close range defense load setup using our
sabot. It has five flattened 45cal balls in it. Flattened into a fat disc weighing
145gr each. You'd star crimp it or use card over them and roll crimp. Like
having a bunch of supersize flat buckshot, only super big.



Here is comparison picture of the 58cal slugs used in our 12ga sabots, with the
puny slugs used in many other sabots. And we've moved 5500 of the sabots.

Re: 12GA From Hell

We have moved few thousand sabots.More here.
Here is picture of an 8ga wad with tube slug in it, we made.



A pallet load of our 585HE cases has arrived in the US
and will be here in little while. And should be another pallet
of them this fall. Here is picture of our 585
with the solid turned CEB bullets in them.



Here is some helpful, simple math to help figure out the kinetic energy
of your loads, just by having bullet weight and speed.
Just put these multipliers which are used for each speed, on a list
and multiply by the bullet weight in grains. Fast and easy.Ed

Speed..Multiplier

you can get molds for from Lyman,
Just make sure they are .574" to .577" diameter.




A barrel of 585HE cases..Ed



Made by Bertram and I tested them to max loads and cases hardly expanded,
650gr over 3000 fps. The same draws used by him to make high pressure
Cheytac cases, and to finish mine just uses belted header and cases left
straight and trimmed longer.He makes tens of thousands Cheytac steady all
the time now and can make ours steady also when needed.....Ed

Re: 12GA From Hell


One of our sabot testers with tight barrel, Abolt, with wide lands in
the barrel, who couldn't do any good at all with our sabot and Alliant Steel
and one type of slug, had to go to IMR 4759.
It would twist up the sabot petals. Terrible accuracy.

My guns have NEF/Sav size barrels and worked fine with Steel as well as 4759.
Petals open perfect. The Abolt barrel is about .005" smaller than NEF/Sav and
the lands over twice as wide as the NEF. And has real narrow grooves.
Guys with Nefs say sabots open fine like ours here.

He went to different Minie slug and our slow powder loads using
IMR 4759 powder up to 78-79 gr and finally got down to 2.5" group, I told him
go to max which is about 80-82 in 3" case.That barrel is like a lot of
EU made barrels and many are replacement or add on barrels in many slug guns,
and that is reason why it is so hard to get accuracy across the board in
sabot shooting in all guns--Takes a lot of work.. Another tester with NEF 12ga using
Alliant Steel with sabots got good groups like we did here. I tell guys if
problems occur go to 4759.

What was happening to sabot petals in the barrel, with the extra tight fit and
wide lands were petals twisting.. The wide lands were not cutting into the base of
sabot like in NEF/Sav210 barrels. The twist effect of rifling was on the surface
of petals, twisting them. It was not getting good hold on the sabot body. The
4759 starting slower allowed the sabot to get its spin started up to speed
with the wide land rifling and narrow grooves..It is just the opposite of
way NEF/Sav 12ga barrels are done. with narrow lands which impress into
the sabot base the way it is supposed to work..I showed pics above of the
good rifling marks impressed into our sabots.

I think after this experimenting run I feel that a lot of accuracy problems
across the spectrum of barrels are due to barrel differences, and not just
the differences in factory slugs and/or reloading components.

Here is pic of bag of our 585 cases with plain head if some need them for
wildcatting.We have quite a few. Fifteen have 585HE cases now. 585 gun
building is accelerating. We can get folks going with 100 cases, dies, and soon
a barrel; and shipping, for 750...Ed

Re: 12GA From Hell

Here is picture of our 12ga sabots with the marks that the barrel lands made, marked with
black marker. The one with narrow mark is Savage barrel and one with wide mark is
an Abolt barrel. And the ones fired in Savage and NEFs with the narrow lands the marks
impressed into the plastic getting good bite and not twisting the petals. The one from abolt
he used slower powder for easier start and it open petals ok, without twisting petals like
the faster powder did for him.


..
Next is picture showing top edge of sabots. Our sabot on left you roll crimp down over
the inside of it a little . We have lots of them yet.
The other factory sabot they crimp real short and sharp
180 degree crimp down on top of it.



We see a use for modified 585 application in Indiana deer hunting. Mainly shotgun only, but
they also allow rifles with over 35cal pistol calibers; and any over 35cal rifle with a case
1.8" or shorter, usually short wildcats. So we have the the 585 HI... The I is for Indiana.
Here is picture of it next to the kinda little 500 S&W. 585 HI holds over 80 gr powder.

Next picture is a Magtech chambered for it. Gets 440gr Minie over 2,100 fps.
The .585"- .587" Minies of 440gr, 540gr, etc work in it, and they're good deer slugs
We got other guns with it going into; bolt guns, like in the last picture,
single shots and checking couple lever actions.
Might work great in MNs many guys like....Ed

Re: 12GA From Hell

funny gun law and like allways in such a situation people looking for a clever interpreting. my first thought was its made for the civil war breech loading carbines to make them like muzzle loader by law.
this is the right thing for the german 40 mm long lancaster bullet cartridges especially if you work with the Gras carbine. many of them were sporeterized as cheap shotguns in 20,24,28 and 32 ga. it would be possible to rifle the shotgun barrel making the gun barrel diameter the land diameter and shot the 40mm long brass case with lead bullets in this.
if the gras action is still original the 32 ga brass is the right stuff and fit the 11 mm gras bolt head. btw, .54 muzzle loader bullets fit like a glove in 32ga magtech brass.



50 Smith brass and plastik case,50 Maynard,54 Gallager, 54 Sharps( one of the different cases design popular for replica sharps in europe)

56 Spencer CF,56 Spencer CF(different case) 32/40 with 54 cal Muzzle loader bullet, 28/40 for my Husqvarna 17a, 20/40, 17mm Danish Snider RF, 18mm French Tabatiere

Re: 12GA From Hell

Law is just a deal to shorten ranges bullets carry for
safety in crowded areas.

The Gras in the picture is 16ga, and they even made a 12ga.
They also in 1880s coverted the original 11mm to 8mm Lebel.
Guy wants to see what is possible with the 585.

The 585HI would be perfect for Nosin Nagant. There are
a million of them. And there plenty of cases to
make them from. Would work in all the short actions
that are the vogue now, get rid of the small bore junk...Ed

Re: 12GA From Hell

In above post we compare the top thickness of sabots
.Here is comparison of the thickness of the sides of two types of
brass 12ga cases, the RMC turned case and the thinner
Magtech drawn case. Easy to see you can't size with same dies
and sometimes you have to use different wads..



In posts earler in the thread you saw variety of wad columns with
12ga sabots and here is picture of my favorite wads to go between
seal and sabot. The white felt ones from BPI. They compress down
evenly on firing, easy to load, decent price,



You've seen the work on our 585HE posted. Folks ask what case
I made first ones from and how. Here is a sketch showing the steps
I used to make the first 585HE from long basic straight Nyati brass.
The start of the belt step I put on the case where it is thick I do it
in my case spinner lathe I made. Then case is lubed and run into
couple swaging/sizing dies and comes out formed into our belted,
straight sided, 585HE case...... It is really faster getting a big
run of cases made in a factory.




Shot a 12ga sabot load w/440 gr Minie bullet in smoothbore Rossi
in 3" case, Going about 1700... .. 4" group 3 shots at 30 yds.
Gun works fine, shoots nice. Got extra weight in the butt.
The Minie I used is a semi-round nose. If I had the ones of same length
with blunt nose, slightly heavier the group size would be smaller as
they'd be more nose heavy, be like Foster slugs..Ed

Re: 12GA From Hell

Here is picture of the group improvement a guy had shooting our
sabots in a real tight barrel. Actually an undersize barrel compared
to Savage and Nef barrels. Had a wide open group with shotgun
powder but made it much smaller using much more
of the slower 4759.



There is a guy now in Canada with our sabots for guys there and
other countries, and as well, he can ship back to here. He plans
on supplying the .58cal slugs also for the sabots if guys can't get
them or don't cast their own.......
Contact is- jeff.a.white at gmail.com
If things work out for him he plans on getting a bunch
our 585 cases imported for sales there

I got some factory 8ga kiln loads, 3 oz lead at 1800 in the long
barrel falling block. Got box of 25 to see how they compared to
the loads we set up.Our favorite is 900gr at 2300. in plastic case.



Here is picture of section 585HE case showing 4 pyrodex 54cal,
60gr equivalent pellets, with a 440 gr Minie bullet.
Actual powder wt is about 185gr....Goes about 2600.

Re: 12GA From Hell

Another use for 58cal Minie Bullets would be to setup a 24ga FH.
Minie bullets cheap to cast and buy. We use the .575-.577" in our
12ga sabot, and the .585-.587 in my 585HE. And you could use
577 NE bullets also.

For those in shotgun only areas there is a way. You can get 2.5"
Magtech brass cases, but also you can set up a 3" chamber and use
577NE 3" brass. Grafs shows some under 4 bucks each. Cheaper
than getting them made. And if you set up chamber with shotgun style
forcing cone you could shoot shorter Magtech as well as plastic cases.
Reason to use 577 cases, they are stronger solid head, last forever,
and can be run higher pressures and still last forever.
You can get barrels, 58cal at Green Mtn I think. .We got some also.

AND the first batch 585 barrels from McGowen has got here, more
will be built.They are the regular 1 to 20 twist barrels, and we have 14
that are profiled and polished, and 3 others that are straight blanks,
1 to 20 twist. And 6 slow twist barrel blanks for guys doing mainly
Minie bullet guns, and bunch smoothbore blanks...Pictures soon.

Here are couple pictures of a 585HE gun a guy is doing with nice
walnut stock. Gun has extra bedding lug and accra-glassed.
It is an Enfield and has single stack magazine.

Re: 12GA From Hell

Here is picture of 24ga FH in the Mossberg bolt gun. On a
Mossy 390 frame, .585" heavy barrel, same as 24ga size.
Chamber is set up 3" with shotgun style forcing cone,
so it can use 2.5" plastic cases and 2.5" Magtech brass
cases with slugs or shot and for 3" cases we use 577NE
3" brass. Really make a hairy 24ga using the 440gr to
540 gr Minie bullets at 21-2400. If you take 540 Minie bullet
mould and leave out base pin you'd have a 650gr that
would do. All these bullets and slugs as well as jacketed and
turned 577/585 bullets work in 24ga as well as my 585HE.
And the smaller Minies work in our 12ga sabots. I keep
saying 58cal is where it is at, and there are more bullet and
slug choices in the .585 size, easy to find, than any other
caliber over 458. And Minies are like 40 cents each and
cheaper if you cast your own.




Here is picture .585" barrels from McGowen, with other barrels.
Most of the McGowens profiled and some straight blanks.
Others we have are the slow twist and smooth blanks...
In back some of the cases and die sets.



Here is picture of an Enfield and a BBK in Hogue recoil
reducing stocks. These stocks are the rubber coated ones with
the easy to grip, nice pistol grip.Has McGowen 26 inch barrels,

Re: 12GA From Hell

Some guys in 12ga like to use the Magtech brass cases
but the cases being brass the sides are thinner than
plastic, and that makes loose fit in 12ga chambers.
And case expand a lot and are harder to resize,
But I found that .750 hollowbase 10ga slug fits
those cases and still chambers ok. Not a sloppy fit.

So If you have a 12ga smooth barrel with full length
backbore job, of .850" bore or bigger you could use
the Magtech brass and ,850" size 10ga hollowbase slugs.

Brett in MN used the a BPI AQ slugs in his full length
backbored 12ga and got fair accuracy as he said the wads
under slugs expanded a lot for a decent fit.
The 10ga slug shown in the 2.5 inch Magtech is 800 gr,
and .850" diameter. These cases will take magnum
pressure so you can get good speed, for what this short
case can hold.

It is too bad they don't make 3" and 3.5" versions.
These 2.5" cases are easier to find and much less than
others, so if needing brass ones you can rig up guns
to work with them. To build a new barreled gun in actual
12ga size, IE .729" bore, you'd make chamber to
minimum specs so cases don't
over expand.ED






Here is the ytube URL again for our guy
shooting 585HE in his NEF----By mid summer we plan on a
pickup truck load of more 585HE cases coming in.

Thanks for making the wads happen in Canada through Jeff White - I got a couple bags of wads and am now about ready to begin experimenting. I have a couple moulds if .575 and .580 as well as STEEL and H's Longshot, IMR 4759 powder along with a can of Blue Dot.

Have you tested any loads with the Lee R.E.A.L. .58 bullet? - at 440gr. in pure lead? The other one I have is a .575 or .577 in the Lyman Enfield minnie bullet at about 560gr. I expect I'll changed the shape of the HB plunger to a thicker skirt and increase the weight to about 580gr.

The R.E.A.L's need a wad inside the base of the cup, I'd think due to their short length.

Re: 12GA From Hell

Here is good simple system with big hollowbase slugs to stop
the skirts from deforming, or wads getting pushed into
the hollow base. I found that dense dow foam works
good, I was using glue gun, but the dense foam is easier, cut
plugs out of foam sheet and force into the base. Make it a
tight fit, use spot of glue inside, glue that is for foam....
Trim off the foam flush..In picture is 10 ga 900gr slug
with foam pressed into the base..



How we get good 24ga plastic seals with protusion on
top that fits up inside 58cal Minie base, same bore as 24ga
and our 585HE. I get the 24ga seal by cutting apart the BPI
24ga Brush wad, getting two seals out of each.Works great
in plastic case giving a shorter column than other seals and
wads, so we can get in enough of our 4759 for good speed.
The 24ga idea is getting nicer all the time with
the variety of cheap 58cal slugs, and good 3" brass cases,
drawn cases, we didn't have to wait to get made.
And all kind of guns we can use, bolt 395 Mossbergs, single
shots of all kinds, Autos,, pumps. bolt action Savage,
even 1887 Win and Greener MKIII, bolt action JC Higgins. .



Here is picture Khan auto we setting up 24ga FH, it is 3.5"
model, has a 12ga barrel to change with. Being 3.5" it
feeds/ejects through lengthened port 3" brass 24ga cases we

Finally got back to forums.Been busy with 24ga FH and 585HE
and getting 585 cases made, as many as possible...

We are now working a bit with 24ga FH and here is picture
of it with our 585HE case. Both use same bullets/slugs, same
bore barrels. Main use difference, 24ga FH easy setup in break
actions and 585HE in bolt actions and falling blocks.



Picture of non-discarding 585/24ga sabot cup I found that holds
458 bullets and slugs tight. It had hammerhead type slug in it that
was pulled out and they wouldn't stay in tight. Sabot was a loose fit
in 20ga, made for 20ga, but small, so I shrunk the bottom rib,
fits perfect, super tight, in 24ga and 585HE. Fits real tight to give
good resistance for good ignition.



Here is another 24ga/585 sabot that holds .452" 45cal pistol
bullets. Made by Hornady for 58cal ML. With 250 gr bullet in 585
will go about mach 4.



Here is easy way to weight plastic stocks with hollow butts, use rubber
coated computer mouse balls, weight comes out perfect without being

Tks for the info. Fora 12 bore bolt gun, they looked pretty good. A recent mangazine - maybe Rifle, has an article on them with sabot loads tested for accuracy at 100yards.

My Mossberg m835 has a .724" groove diameter - sung.
I've a few rounds loaded with the .58 sabot and double round ball loads, but so far, haven't papered it. I thought they might make good Spring Black Bear loads. Good to note about the sabot diameters - thanks again.

Re: 12GA From Hell

Here is picture of 100 cases loaded with CEB solid nose bullets
and hollowpoints. This bullet is a turned solid with wide meplat
or wide hollowpoint. .



Here is picture of triball loads that fellows like for deer and hogs,
and just general tear em up fun, with using BPGS seal to improve
sealing under what are heavier loads. The balls are .600" and
315gr. each. The wadcup is a TUPRW123 that Precision sells.



I need a bunch of empty 3.5" 20ga plastic cases.


Our 585 caliber is modern bolt action continuance of the 577 Nitro
Express rimmed case, that many big game hunters like, usually
set up in double rifles. It has an interesting history, from the old 24ga
size to 577NE, to 585 Nyati with G&A picture of Ross Seyfreid
shooting one in a Ruger #1 under recoil knocking his shooting glasses
off, to the Trex of internet fame knocking guys over with recoil,
to our 585HE the strongest yet.

The 577NE is an offshoot of 24 gauge caliber paper cases, only they went
eventially to brass cases. Back in the 1860-70s, starting first with short
cases and black powder, cases built like shotgun cases, called the
577 Snider, then going to coiled brass cases, still with black powder,
then on to drawn brass cases, called 577 BP Express. then to 3"
and other longer cases with smokeless. The Snider started out with a bullet
of .570" diameter and through the progression to the 577NE bullet
diameter ended up at .585". This general bore diameter of cartridge guns
and muzzle loaders, it is really interesting on how they developed
and were used by military and then hunters over the years. The Snider
was necked down to make the 577-450 , a military round used all
over the British Empire, by the tens of millions.

Bases of both 24ga and 577NE are about the same. Now we have made a
24ga FH, a slight regression to earlier times, by taking 577NE brass, and
reducing rim diameter to 24ga specs. Two minute job. And
stamp the caseheads 24 ga.

For shotgun upgrading in power and range, It is all about increasing
the power in easy to find brass cases, stronger actions, and finding
reasonable price rifled barrels. Same barrels we found for 585, work for 24ga.
The 577NE brass we make 24ga drawn cases from, for example are
about a third the cost of 600NE brass, or getting turned 24ga cases made.
We could use 24ga thin cases but they are a pain, expand way too much,
with slug loads which makes resizing without crumpling cases a problem.

Info about the power in types of guns normally set up with 24ga FH,
break actions, bolt shotguns,etc. In thin brass 24ga case, 440gr slug
goes 1500, with about 2000 ft lbs, that's in a 2.5" Magtech brass case.
Now using the better, heavier 3" brass we got, we can increase speed
to 1750 fps increasing energy 50%, going to 2000 fps about doubles
energy. And going to 2300 which good brass holds ok, in heavy barrel
gun, gets us near 2 1/2 times the energy. About 37-40,000 psi which the
actions hold in this smaller diameter case, compared to 12 gauge size.
So makes relatively smaller bore shotgun, 24ga, with 458WIN power.
.Perfect with Minie bullets. Perfect for deer and hogs, bear, etc.

Great for slug hunting in shotgun only areas. We mark barrels 24ga
and cases 24. A decent case that is complimentary to our 585HE....Ed

middle bands on the CEB and it fit perfect in our 12ga sabot,
which uses .575" slugs. Hollowpoint one pictured 700gr in the

special made hollowed out long roll crimper.



Getting some more interest in our 585HE.
An application for our 585 HE is for guys with old military 14.5mm
PTRDs, to use our case with chamber insert. In many places 14.5
cases are scarce, real expensive, as well as most 14.5mm cases
being steel are not the easiest to resize/reload. Our case sizes
like regular cases and can be easily reloaded many times.

And a PTRD with almost a 5 foot long barrel could get 650gr
spitzer bullet to about same speed the 14.5mm gets a 900 gr using
3 times as much powder. About 3300 fps. Or get a 900gr at 2800.
Great possibilities for fun shooting. For tactical use in a place
where it would be useful to reload in the operations field, where
steel cases are scarce. 100 of our cases do over 2000 reloads.



I like Enfields to put our 585HEs in, for reasonable cost guns, the
actions once sporterized are one of the longest for long cases. .
Here is inexpensive way to fancy up the Enfield Bolt handle by
cutting the dogleg part of the old handle off and welding on
inexpensive contoured handles I found, one of which is like
Ruger 77 handle, the one on the right . Something even a novice
like me can do.....



A lot of guys are crazy about CEB bullets. Here are light 450gr
ones in our 24ga FH. That hollowpoint can range in weight 450gr
to 700gr depending on how much we cut off the back..
The 24ga FH brass case is nice complement to our 585HE,
for shotgun only deer hunters that want a .585" caliber,
and easy to find big bore bullets.... Ed

Re: 12GA From Hell

For lightweight plinking, deer hunting, etc, in 585HE as well as 24ga FH
here is picture of 58cal Hornady sabot that holds .451/.452" light
bullets 225 to 300 gr. A way to shoot targets economically. Low recoil
but a big bang and satisfaction. A 250 gr bullet would go about
mach 4 with a top load..



Here is what 585 bull barrel, target blank looks like, 1 5/8" OD and 32" long.
It'll go in heavy action of some kind. 4th one from the left. The one in yellow
sleave on top, is a heavy contoured one with muzzle of .980". we got a
bunch of them and so does McGowen.




Here is picture, nice cast bullet I like for the 585HE and 24ga FH.
It is .585" diameter and 650 gr and these particular ones are a
hard lead alloy, plus they've been heatreated. They are about as
hard as copper jacketed softs pivtured. These in .575'' size would
work in our 12ga sabot..



But to penetrate good and do great damage to game or target they
can be fairly soft lead and hollowbase like Minie Bullets. Here is picture
of timber drilled through with .585 soft lead Minie from 585HE.
Picture is the back of 6x6 timbers where Minie bullets came out.

Of our 585HE in first Ruger #1, that was done in Australia.It was set up
for the poster Tankhunter on the AR big bore forums. That gun killed the

Re: 12GA From Hell

The 12ga FH isn't the first wildcat case built on BMG brass, it was preceded by
target rounds like the necked down 338 Talbot, the cut off 700 DKT for big game,
necked down to .416 and . 458, and more, but the following one was way
before them, in my favorite rifle caliber, for .585" bullets.

One of first modern era 585 caliber wildcats, since WW2, the 575 Miller-Greiss Magnum,
was first mentioned in the fifties, It was made from BMG brass shortened to 2.70" long
and necked up from 50 cal to .585". But actually if cut off first, it would be annealed, necked
down to hold 585 bullet. Fairly sharp shoulder.

They rebated the rim quite a ways down to .618" to maybe fit 98 Mauser bolt.
Maybe used a special hogged out, reworked action. Listed as
shooting 750gr bullet about 2400 fps. It holds about 150gr of ball powder under
a 750 gr bullet, maybe little less than 3" 50cal spotter case, where our 585HE holds
180gr under a 750gr'.

We made one for experimenting on a full length BMG case.With rim left same as the base
and would need a BMG or PH sized bolt and action. I'm glad to be a big bore wildcatter,
and happy to be in the company of big bore nuts, old and new. Years ago when guys did
big wildcats on BMGs, they took what was available, full length BMGs to rework, and but
maybe back then they could have used the 3" BMG spotter case, by shortening the neck,
if they could have found couple barrels full.

But it takes a lot of work to reform and shorten cases that much like M&G, with the multiple dies,
multiple annealings, and case trimming and extreme reworking of regular rifle actions,
which is why I like our 585 case, simple and straight, any regular, long bolt action, or
falling blocks, break actions, etc, a 585 good for dozen or more heavy loadings,
and moderate loads, last forever..

For our 585HE , made it a size, actually new belted size, to fit regular size, long bolt guns,
(not BMG actions)that didn't have to be used from tripod so to speak, and could be put in a favorite
gun of many, the Ruger #1, other falling blocks, without taking metal out of the feed trough.
To get the same and/or more powder space as a cut back, really shortened, BMG case, like M&G,
wildcatted to 585, or other short cases, we made longer case and worked with guys
with a group buy, to get a factory run made. A miracle. We thank all gun nuts for the help.

Here is picture from the great site, cartridgecollector dot net, of the M&G Mag .Ed

Re: 12GA From Hell

Probably first 375 caliber cartridge made from 585HE necked down, the 375 Warlord.

Guy did a real nice job, with what looks similiar to a Weatherby style shoulder.

Kinda outdoes Weatherby & Cheytac. We have cases with no headstamps for wildcatters.

First picture I got sent me today off of facebook and this one is from the great sniperforums.





Another fellow is planning on shortening the 585HE to maybe 2.4", for use Marlins and Henrys,

and other leverguns, redoing their 45-70s. With the belt they will have good headspace control.

Without a rim that takes up circular space, say like our 24ga FH, a 585 bore, but which is perfect

with a rim for break actions like our 24ga FH in a Magtech...Ed

Here are couple 24ga FHs in break actions, a CBC with monoblocked
a 585 barrel into, and a guys NEF he monoblocked in a 585 barrel.
The 585 barrels are perfect fit for 24ga and 585 Minie Bullets
are a perfect for barrel and 24ga case fit.





Another matter--- I know it seems like I'm begging for help when
I ask guys on the net for help at times. . But I really am in a bind.

That is the truth, Our small income disappeared from our farms truck
garden business as my my knees are shot and can't hardly
walk, I can't do field work, etc. And the wife's lung condition
got so bad she can't work, nearly invalid. We need extra money to try
to keep our health fixed up and pay bunch of back bills and utilities.
As well needed to pay for traveling to doctors, treatments,drugs, etc.

Could you all maybe get together with others on these forums
and kinda take up a collection to help get me out of my troubles and
debt. Like 10 or so bucks each put into my paypal account as gifts.
And if you want to mail it, use email below to have me get you
my mailing address.

The Paypal email is je@gunownerstv.com

PS-- I really need help. Not a astronomocal amount, but fairly fast.
We never made anything on the 12ga FH work and research.

Re: 12GA From Hell


Here is picture of a lightweight Barnes bullet in 24ga FH.
Guys cut the back off of 750gr bullet off to get 500gr weight.



Here is picture 58 cal Minie slug that's little long on the side for our 12ga
sabot, with the front of the slug above the grooves swaged to fit in
sabot. The swaged front third of the slug fits next to the internal ridge in
sabot and the sabot doesn't bulge out.Just run front into a die
and punch it back out.




And some info about 12ga FH and other hopped up shotgun slug loads,
You know we like to use the rifle, IE slower than shotgun, powders.
We like to use IMR 4759 for some loads and RE17 for others where
we have room for larger charges. Those two powders are ignited ok in large
diameter cases like 12ga, 10ga, 16ga, etc, without needing BMG primers.
But we have always been looking for easy to ignite powders of the RE17
type, when cold, that has a speed between IMR 4759 and the RE17.
RE17 uses different process to put the deterrents in the powder to control
speeds, which allows much easier ignition, compared to big majority of rifle
powders with all the deterrent on the outside.

There are some out there made by Nitrochemie Switzerland, who makes
RE17, RE26, RE33, etc, for Alliant. It's the ' RELOAD SWISS' brand available
for those in UK and Europe, They are called RS 40, about same speed
as RE12, RS 50 & 52, same speed as RE15, RE60 & 62 same as RE17.
Also one ' Vihta Vouri ' powder called TR140 available over there,
that Nitrochemie made..

Many guys can't get IMR 4759 anymore, some can't get RE17.
I'd like to get some of RS 40-50-52 powders or V V TR140
into the states, would really be great help for hairy slug load work.
And guys in UK/EU now can load some real hairy, slow powder, slug loads,
even though not having IMR 4759....Ed

Re: 12GA From Hell

We got guys wildcatting our 585HE case,




Here is picture of that 375 Warlord next to our 585 case he made it from.
He is going to make couple later necked down to 416, and 458.
There is another guy working on doing one necked down to 357 wildcat.



Here is a picture of our poster Biebs on AR, 585 HE, in a MPI stock.
He used a big Enfield action, with a fancy jeweled bolt.



We found couple other big actions for our 585, that can even feed really
long overall length loaded cases, like 4.5" long or more, if you are
using long pointed bullets for real long range target and hunting work.
One is Lawton 8000 Cheytac action, and the other is Stiller Cheytac actions
made similar, just a newer version. Both actions come in 1.45" diameter
and a 1.60" diameter receivers.

And Vestals Gunsmithing in Virginia does great work, decent prices, has
these actions and will build you fancy 585 HEs. .. He has, working with
another guys mag box setup, setup an extra long, good working, single
stack, center feed, magazine..He has one of our 585 HE reamers on hand,
we have barrels....Ed

Re: 12GA From Hell

Here we kill two birds with one stone so to speak,

Best case sizer is the MEC Collet Super Sizer and it can double
as a case holder when we roll crimp. Much better hold than
the ones made to hold cases for crimping, that cost a lot.
Save cost of a holder, plus have best sizer around



Here is couple different setups our guys checking for our 585HE
in a long, Lawton Cheytac action. First laminated thumbhole stock.
Second in a Hogue Compstock. The action can mount a scope rail
like shown on the table in 1st picture or a receiver sight in 2nd picture.
The scope rail is a piccatiny type.





The stocks used were wide ones for REM long actions, just add recoil
block ahead of recoil inleting for the longer action, drill new screw hole
Open the stock forward to original bolt hole for longer cases and mag.

About Enfields for our case, one of my favorites, Some don't like the
sporterizing, welding bottom metal straight. Many think straightening
is a huge job needing special jigs. Easier just use one being added on for a jig
with a bolt, to weld on the straight extension, Do top weld, then cut old
extension that is under off with a thin cutting wheel, then weld bottom.
When we bolt the short piece on the one we are straightening, we grind
the short slant off so the added piece lays on there flat.
The one you cut off can be used as the top extension for the next one!!!
Just keep on building...Ed

I have a few of those Enfields (P14's here) in the draw some already sporterizied (nice trick on the mag welding), I just hate that safety & the lack of nice stocks for them, also now days only want my over 45's in SXS !

Re: 12GA From Hell

Thankyou, yes I like the MEC sizer, makes cases better than new.

Richards in California makes good laminated stocks for Enfields.

The stocks I like best and I'm not a fancy stock guy, are the

Hogue stocks, and their hollow butt is easy to put weight into

for our heavier recoiling cartridge. Filled full of rubber coated

steel balls.. That is the old computer mouse balls.

Now they are not made specifically for Enfields, but ones for long

action Howa/Vanguard/SW1500, fits good with a little extra work.

And there are many pillar bedded ones for sale on Gun Broker. Ed

stock, handles recoil great.Neat looking work... Ed




About our 2.17" 585 BB case for lever guns, pistols, etc,.
It is made from our 585 case cut back to 2.17" long.
With loaded length of about 2.8" work in lever guns, etc.
Work in 71s, later 1886s, Henry steel frames made for 45-70.
One guy is putting one in single shot action set up with
Contender style pistol grip for testing in long rifle barrel,
to simulate pistol recoil..Be very brisk recoil in a case
that holds 110 gr powder under a light Minie bullet.
Maybe work in a Rossi Judge with heavy barrel.
Or rolling block rifles and pistols...Gonna try one in 1887.
Got first one in one of our guys Greener GP for testing..

In some ways big bore shotguns and rifles are sexy.
By looking at the shape of the fire and smoke cloud....
Thanks for picture, to the great NitroExpress Forums site.




Here is picture of another neat sporterizing deal for Enfields.
On those without rear bridge pocket welded up, we just mill down
and shape it so debth of the pocket matches bottom section of
weaver rail and screw or epoxy it in. Shape to drive in hole tight.
Can use as a rear scope ring mount or mount for peep sight
like a compact UTG sight...Ed

A poster reading our threads said '' I'm slowly becoming a recoilapheliac''..
That is neat term , and very glad that folks are catching the big bore fever.

Here is a simple, yet neat peep sight we can use on the rear sporterized
bridges of Enfields, and it works on other rear bridges also. I like peep
sights the best for most shooting. You can get them with flat bottoms
also for bridges that are flat on top.



Another picture of the 585 HE one of our guys put in the MPI stock..



On straight sided cases like our 585 HE the die set has a mouth expander
die to make it easy to insert bullets. The die flares the mouth, but I always
felt that doing what is really a relative relatively sharp flare, and then roll
crimping the same area of the case.shortens case life.

So I just use expander plug out of the die, by hand, using just the bottom of
of the expander plug and just push it in a little, wobble it around a small
amount, bullet goes in ok, case mouths last longer, good for dozens of loads,
with moderate hunting and target loads.Only takes a few seconds and less
work that has to be done in the press ... Ed

that we have, is the Magtech.

Well the guys have found one that is super strong lockup and looks
real nice. And has the good quality look. It comes 12ga light shot barrel,
soon be monoblocked to rifled 24ga FH, the little brother of the 585HE.

We told company if they did them with NEF style, rifled, heavy slug barrel,
for shotgun caliber only hunters, they couldn't make them fast enough.

About the local fellow here making 375 wildcat with our 585 case-


Hello Mr. Hubel,


We just got back on Saturday from competing at the King of 2 Miles Match in New Mexico.


We won! I came in first shooting my rifle (the one I brought over and showed you),

chambered in .375 Lethal Magnum, the round I designed based off of your case.


Iím attaching a bunch of pictures, feel free to post any of them that you want.

I do have one picture of the screen of the camera system looking at the 2500-yard target.

The hit farthest to the left and the hit farthest to the right were my 1st and 2nd shots.



Iím getting more interest in this cartridge now that the results

from this match are spreading across the web.

Happy 4th!

Take care,


Mitchell Fitzpatrick

Lethal Precision Arms

1(989)578-2576

wadcup, good for fullbore roundballs that are too big to go in cup.

Best one to cut off is shortest `12ga one BPI has.






Here is picture of a 585HE made on a Stiller bolt action for guy in Canada.

It was made for the poster Spooksar on Africa Hunting and [blank],

by Corlanes/Rocky Mountain rifles, in Dawson Creek BC Canada, with a

Stiller action, Timney trigger. the stock is a blue/grey laminate. He imported

the barrel, cases, dies, etc.. from us, through Prophet River in Lloydminster AB.






That action similar to Lawton we had and neighbor got, that won the King Of The

2 Mile shoot at Whittington, with the 375 Lethal cartridge the neighbor made,

from our 585 brass. Made it full length case,.. It is big one on the right.

.375 Lethal Precision Arms LLC rifle shooting prototype solid 400gr Berger bullets.

Mitchell built this rifle himself using a McMillan A5 Super Mag stock, Rock Creek barrel,

Nightforce ATACR MOA scope, Phoenix Precision Bipod, and a Lethal Precision Arms

muzzle brake. Lawton Action. Lethal Precision his own gunsmith shop, will make

these target rifles for anyone into target shooting and long range hunting..


Remarkably, Mitchell nailed first- and second- shot hits at the 2477-yard target,

a full 1.4 miles away. It is windy out there, makes shooting hard with a time limit.

The prototype 400 grain Berger Bullets solid was superb, (G7 BC of 0.56 at 3000 fps).

Re: 12GA From Hell

Our friend Brian from the far north went to Africa with his 24ga FH he did in
a NEF break action and got 3 nice buffs with it. Good job.


Our 585HE, 700HE and the great 12ga FH are now in the new COTW book
published in Oct, now out for sale,




We now have our target 375 HE cartridge, made by necking down our 585 HE.
The others couldn't make enough 375s, so we started our own. It has different
shoulder taper, length, neck length, improved over the others...Got a bunch
guys doing it, most into the 2 mile shooting venues, We're making cases,
testing, reamer prints at reamer guys, we are getting guys going. The 2 mile
shoot last year really got the interest booming for 375 necked from our case,

Here's how, size and seat 375 HE, one simple die, a 1" die, no huge dies needed
A die we can make with resize reamer from reamer guy, a regular die body,then
pass on to the next guy, one reamer can make whole bunch of dies for folks.

I do primer work separate, not in the press. SO First with lock ring set, I size cases.

When coming back out of dies with case, we notice the case still well centered,
held straight, when it is down as far as the length of the 375 HE neck... IE
the sides and shoulder corner still supported tight.

So we put washer or another lock ring on, same thickness as neck length,
below original lock ring, screw down tight tight in press,

Dies had a 5/8 x 24 thread in top, had powder fill bushing and other stuff same thread,
reamed out from bottom to set bullet height, with ram, case,and bullet up,

After priming, loading in the powder charge, we carefully start(boat tail makes it easy)
bullet in case by hand, slide up in die, into holder, raise ram to to top, bullet seated
perfect. Die can have different thread in top as long as big enough to hold seating
bushing of some kind , that can be made from many items.

These target bullets held in by strong neck tension, no crimping needed, and notice
bullet point will get no marks or dents, fast, easy, no 380-500 buck special dies.
Bushing centering bullet on ogive is very accurate.

OVER 900 375HE cases piled behind presses getting done. About 600 on another
bench nearly ready. Small batches in shelves.And we will do more.

All 375 info, prints, specs, pictures, load data, etc, is public domain, worldwide,
for any target, hunting, etc, use..Ed

Re: 12GA From Hell

Cool to see Ed, you deserve the recognition !

And folks said I was crazy when I made a NEF in 500 3 1-4in NE, but boy did that thing have recoil in full loads !!

Re: 12GA From Hell

Here is picture of one of 3 buffs our guy from Canada got in

Africa with our 24ga FH he did on a NEF, in 2nd picture








Here is the neck die setup, with insert stems/plugs for the top that

are set in .020" steps to make our 375 HEs shown behind

from our 585HE cases. 900 cases behind and 600 on

another bench, mostly done, and 600 started elsewhere,

We also made a hydraulic form die, 375 HE test gun, starting with

lighter bullets, for example got 340 gr to 3700,

Will test up to 400gr We will find top speeds and powders needed

to get that, and have info where to get powders. Reamer prints are

at reamer guys, all prints and info is public domain... Ed

Re: 12GA From Hell

Picture of fellows at Vestals Gunsmithing test firing 585 HE

they built for a guy. They got 750 gr to almost 2800 from

ultra short barrel, not a full load . A regular barrel would be

over 2900, 14000 ft lbs with full load..





Picture of our 375 HE cases, with little 378 WEA on left.

Middle case is with 330 gr, right case is 400gr bullet.




Here is picture of out 375HE testgun, in heavy t-hole stock.

So far 340 gr to 3700 and 360gr 3600.




Next 416 HE target case, these run through the hydro-die,

test gun done,will complete testing soon, to confirm specs.

When specs set, info will be sent to reamer guys

Soon will have 408 HE with specs set up also, for guys,

Smaller case 416s and 408s can be reamed out for

our bigger case .Ed

Re: 12GA From Hell




Here is the before and after of 375 HE cases
necked, 2 on left, and then formed in hydro die... Ed




Here is pic of 416 HSM second from left we are experimenting
with, going to see if we can make the ultimate 416 ELR case.
Can be 3.60" to 4.00" long, a long one pictured.
Holds over 280 gr ball powder under bullet. The
3.6" case can hold about 250gr under bullet.. In picture,
1st case is 416 HE, 2nd 416 HSM, 3rd 375 He, 4th 378 WEA.

416 HSM will get 400gr to 4100 plus without needing BMG action,
470 gr 3800 plus , it may be the ultimate target, singleshot 416..
Case will work in fat bolt actions, with heavy enough barrel
to have good, milder, barrel harmonics and be under 50 lbs.
A lot of the 2 mile type shoots are adopting 50lb limit.



Here is picture of the 416 HSM fireformed once,
next to bmg case we make it from and as we
improve wildcatting process next few weeks
some specs may make small changes, now from
base to shoulder is 3.45", case 3.97" long. Ed..





Manson has 416 HE and 408 HE prints, as well as 375 HE
He can also make you a resize die reamer from that info.
We got 700 cases in 416 and one more pass if 408s wanted, ,
Going to do lot more cases for these 2 sizes,
PM or email. ph 989-644-5228..

Here are final specs for 416 HE.
Length 3.32", belt diameter ,655", base dia .635" ,
length base to to shoulder 2.860" , 30 deg shoulder.Ed

Re: 12GA From Hell

Guys asking about strong economical bolt gun to use for 28ga and
410 ga and 32ga with brass cases and higher pressures than plastic cases.
They can use a MN bolt action, here is pic of one with
our 585 case in the action.Guys can get Magtech brass cases or have
RMC make them....Guys can make 32ga case from 500 NE,
410s from 9.3 x 74 brass, etc..



Here is picture of our 416 HSM case sectioned next to original
BMG case on the right sectioned, to show that we still have
enough thickness in the sides to handle high pressure,
in a case with 310 gr capacity..We are getting the wildcatting
work set up so we can do at least hundred a month.
We have lots of 585s, 375HEs, 416 HEs, 408 HEs.....
And working toward getting 416 HSMs in big numbers.



Here's comparison of 416 target cases, 1st 416 HE, have whole bunch.
Second is model of what I'd have made on medium machine, if I could,
the 416 HE Long. It has capacity of 230gr..
Third is our 416 HSM which we are working on making by wildcatting bmg
cases, And if had run long cases, make longer 375 HE necking down 416 ..




Bryan Litz just recently shot 3 shot group at 2 miles using Paul
Phillips heavy barreled, target rifle built by Lethal Precision in
375 Lethal Mag(585HE necked down, very similiar to 375HE )...
It grouped 17.5 inches tall by 22 inches wide.

Applied Ballistics shooter Mitch Fitzpatrick just hit 3 of 5 at 3520 yards,
weekend 10-13th at Valdina Ranch , west of San Antonio.
Also used the 375 LM case similar to our 375 HE
Great shooting at the 2017 World's Longest Shot Challenge. Ed

Re: 12GA From Hell

The 12ga FH case now is in the new COTW book on
last page in the wildcat section, I think page 324.
They gave good credit to Rob for the idea of that case....


The model 416 HE long case in middle, hydro formed one,

has case capacity of 240 gr, and the 416 HSM in picture,

on the right, we fired a case twice, capacity is 320gr.. Ed..




Shooters talking more now; short, fat cases sticking, pockets not lasting as expected.
Trying to get best speeds the things raising pressures are bad case proportions, too fast of
powders, and the debth of the bullet into the powder space, as shown in the picture below..
My 375, 416, etc testing, bullets loaded like bottom one, in longer freebore....Ed.

Re: 12GA From Hell

Here is recap simple setup to get faster loads with 12ga sabots

& slugs, Example using break actions...., reaming chamber

in a 12ga break action to 3.5" with a 3.5" 12ga reamer, that isn't

something needing special order, and use 3.5" plastic cases , or

get 3.5" brass cases made. With mag shotgun primers and

our slower powder loads you can get a quarter more speed,

which gives 50% more energy...


585 Hubel Express video, 190ft/lbs recoil, heavy load, gun little light.....

Re: 12GA From Hell

Here in picture of the cases, are shown the steps in making

our 416 HSM case, from BMG brass,, Ed




We might have a company that is doing a bolt gun with an action

between BMG size and longer rifle actions used for 375 HE,

375 Lethal, and Cheytacs.. To use for our 416 HSM without

having to do extreme rebating of the rim.


Here is picture of 620 416 hsm cases half done. Done on cnc ,

that slimmed them down, cut new rim and extractor groove.

There are over 500 more at cnc getting done now, plus we have

1000s more bmg cases we make them from, when needed..

This case is public domain and if anyone wants to make

them we can give the steps involved...Ed.

Re: 12GA From Hell

For big long cases our testing is showing that the 416 easier to get powders to work with, less problems ..
Maybe building a target gun,don't have 375 barrel all ready, maybe go 416....

We got cases, 416 HE and 416 HSM, as well as 375...
CEB and others will have bullets...CEB will be doing .416 in 450gr, 475gr, 500gr, 525gr and 550gr

Got sent 5 thick sided sample cases, same OD base as 585/375.416 cases, same belt, just .180" longer,
did a 416 HE, chambered extra barrel , cases stick over 50k. They have about .042" total taper, .021" per
side, when I necked couple to 416. That is a lot of taper , twice the taper of my 416HE...hanging up at 50k..
