The drive keys I see are cast in to the lead slug.
They do not appear to protrude enough to contact the rifle's bore or groove
My sense is that they are there to positively transmit the rifling's drive to the projectile.
Looks neat.

I'm with Daryl on filling the bore - might as well get the most out of those nice 20bore tubes!

How has your further testing of roundball been working out?
Have you tried any more hardened roundball and different powder charges?
The hard roundball is sure to not tumble through your game animal...

Tinker.

Life has been dominating the hobby lately.
Hope to get back to it soon.

Tinker, Daryl

The RB are very accurate.
I am still dealing with some leading.
I tried some loads with a wad in the brass case.
I will report back soon.
They are a bear to load as the wad fits so tight in the brass it acts like an air shock.
I need to find a way to "burp" the wad to get it down tight on the powder.

Sitting the wads on their edge and pressing the back edge of a stainless kitchen knife into the edge will make a slight V allowing the air to escape. Some of the guys have to do this with waxy lubed wads for muzzleoading shotguns.

The wad still seals on the way out as it is pressed radially by the powder gasses and a wad above which obturates it out again. The groove needs only to be very small to allow the escape of air when pressing them down.

A lubed cloth 8 ounce or 10 ounce (.019" to .022") denim patch around a .600" ball would be almost as heavy as the .615"(true 20 bore) or .620" and it would eliminate all leading as well - just a thought. Weight would be just over or around 300gr. in WW and if Water or oven hardened, they'd probably penetrate like a 500gr. sold lead slug or better. I would expect both shoulders on a moose or elk if driven to around 1,800fps or above.

Daryl
Thanks for the tip, was thinking a piece of steel tig welding filler rod down the side of the case
Would do the same thing, and after seating the wad you could pull it out.
As you said the wad skirt should seal upon firing.

The first card wad is usually the 'tight, sealing one and a quick push with thumb nail will also crease it enough to let the air pass by. Heavily waxed fibers could also be a problem I suspect.

What did you choose as a regulation load?
What's the velocity?
What's the accuracy for each barrel and will you have the barrels adjusted one more time before the builder installs the sights?

Tinker

Lightfield hybrid EXP 20 ga. Mag. 3" 385 grain.
Chrony says 1600 fps.
1" horizontal at 50 yds, 1" verticle composite (3 shot groups) group center to group center.
One hole at 25 yards.
No we are leaving them alone.
I believe the gun is regulated better than I am shooting or the consistency of the ammo.
More testing will be done upon its return.

Nitro.

PS, will post iron sight in targets when I get them.

Nitro - sounds as if the barrels are shooting together at 25, then diverging at 50yards. This might limit your accurate hitting to 100 or 125yards, which might be all you need or want, of course.

Some work on handloads might get them shooting parallel or shooting together at 75 or 100yards, which might be better - lots of time to work on it though for finetuning if actually needed.

Sounds very good so far.

I really like the writing script for the stamping. I didn't see hammer strike engraving, but then, the writing/engraving might have been done with power, thus no chisel marks. Nicely done, regardless- looks good.

Daryl

It has been an epic journey for sure, one of the most educational and enjoyable in a long time.
It has inspired me to consider trying one myself, after some machinists training.
I may ask the Smith to adopt me for a while.

Update 11/11/12

I shot her since I got her back.



The top group 4 shots, scope at 38 yards. (Sitting) 2" wide no vert, R 3 shots in 1".

Bottom group 4 shots irons, leaning against tree, 32 yards 2" x 2"

I need to move the bottom group up it was a little low, will put higher rear sight in.

Congratulations NITRO! I've been waiting for the final lap in your run on that jewel, and it was worth the wait for sure! That thing sure shoots a better than that Sabatti you had down a at the ranch a few years ago! Your smith out did himself on that 20 bore!

I can't wait to shoot that thing the next time you and your family come back to Texas for a little hunting. I bet that little one is getting big now! We've missed you at the DRSS hunts/shoots. Again congratulations!
