Finally shot the pedersoli Kodiak 12 bore
      #44011 - 15/12/05 06:29 AM

Well I got to shootit this weekend; however only shot it 8 times. The weather was closing in and it was getting dark. No real data on regulation yet, I didn't have a bench to rest on so my shots were standing off hand..and pretty crappy. They all hit the target at about 30 yrds. I started at 80 grains of pyrodex ffg and worked up to 130 with not ill effects noticed. The kick is quite mild I think, just a big push. I've shot 458 and 45-70's in really light guns, they were painful, this thing is quite delightful compared. One thing is for sure, it makes a really BIG hole on the target and backing bank.

What kind of velocity are you getting?

I would expect 130gr. of pyrodex to give around 1,200fps.

I agree with Banzaibird. Some pictures please! If you didn't take any on this outing, then please take them on your next one.

Good shooting!

Jason: You're right about the holes in the target. No need for a spotting scope to check out your groups! The fun part with Kodiaks is figuring out what load will make the barrels cross at your intended range using just one of the rear sight sets.

OK I might be a little lost on this one.

Are you talking about a muzzleloader that is a 12 gauge that you are shooting slugs out of? Or are we talking about one of the breech loaders that was converted to a 12 bore (rifled) gun?

It is a .72 cal (12 bore) double muzzleloader rifle with a 1:75 twist from Pedersoli. It has two folding rear sights, the rear most sight is used for both barrels at 50yrds ( regulated per the factory). The front rear sight is for the left barrel for what ever distance you want to sight it in at. At least this is what I have read. Most people sight the left barrel for 100yrds.

It has been very, very cold here in Denver, so my shooting time has been nil. You can't even load the thing in 10 degree weather because the butter bore freezes!

If you've read the story of the guy who made a 4 bore, you can get an idea what this is like to shoot. Lots of smoke, a big shove back and the barrels pointing up. Its a hoot!

I'll take some this weekend of me shooting it. Hopefully the weather will co-op. I have some of the gun apart, but they didn't turn out so good.

Just came back from shooting it. Heres the results thus far.

1. 80 Grs Pyrodex FFg Hogdens 975 FPS best.

2. 120 Grs " " " 1197 FPS best.

3. 130 Grs " " " 1298 FPS best.

This is with a .715 lead round ball 545 grs weight.

Bench rest group, best was with 80 grs and about 3". Higher FPS caused crossing at 50 yrds but speed was only 5" and barrel groups were about 1.5". My shooting was not the greatest and I'm sure I flinched on the large loads. Also some of the loads I tried no swabbing between rounds and some I did. That seemed to help with flyers. I think the way to shoot it is to sight the rear sight for the righ barrel and adjust for crossing for close quarter shooting and sight the rear sight for the left barrel and long range shooting. A delta of 5 inches with open sights at 50 to 100 yrds is more luck than gun I think. I think I can get the groups tigher with a little smithing and testing .

Colorado,

This is how I suggest you go about finding the best load for your muzzle loader:

Start with 80gr of powder and shoot 3 shots from each barrel. As your sights are adjustable, don’t worry where the six shot group ends up on the target, you can move it later. Save your targets.

Up the load to 90gr, and repeat the above procedure.

Continue adding 10gr at a time until you reach 120-130.

What you are trying to do is find the best COMPOSIT group.

When shooting off the rest, hold the forearm in your hand and let the gun recoil as naturally as possible. Recoil is factored into the regulation.

Things not to do:

1: different loads for each barrel.
2: using two sights.

Things to do:

1: Be very precise
2: Be very consistent
3: Have much patience.

Also, don’t mess with the chrono while you are finding the “regulation” load, it will be distracting.

Skeens,

I only had time for 10 shots and I wanted to test the new chrono, get basic idea of regulation and jury rig up a bench at the new shooting site. I will tomorrow conduct a controlled experiment to determine as much functional data as I can in the allotted time. I’m sure it will take many shooting sessions to get the gun sorted out, which is half and/or most of the fun of owning a BP and DR.

As you might know, different BP powders, patch thickness, lube, primer and metal density all play a part in accuracy. So the first thing is to find out the BP part, then the regulation part. Remember this is like having two BP guns, and BP guns each have a personality.

As well since you’re my brother….Yeah, yeah, yeah …..I know

My own shooting with large bores has shown better accuracy when shooting "dirty". That is, my groups are more consistant and velocity readings more consistant when shot without cleaning or swabbing between shots or within groups of shots.
: If I understood correctly, anything over 80gr. opens up the groups by crossing the barrels. This is unfortunate.
: Have you shot black powder in it? Pyrodex is NOT black powder, and neither is T-7.
: Both of these BP replacements foul very little compared to real BP, yet I have never had to clean between shots or between groups with real BP, which is the only powder I use.
: Try to find some 2F GOEX, Swiss or Sheutzen black powder and let us know how that shoots. As well, you might try GOEX black powder in 1F grind. 1F is generally for large bores and black powder ctgs. Some guns prefer it. Mine preferred 2F for heavy charges. With 82gr., I could use 3F and receive 1,200fps, but any more would burn patches, so I had to use 2F for more velocity.(69 cal.)
: A good lube in large bores is Stumpy's Moose Snot. 2oxz. beeswax, 8oz castor oil, 1-1/2oz murphy's oil soap. The oil soap is necessary to cmbine beeswax and castor oil, and is added when the castor and beeswax are hot and well stirred. Add the Murphy's then whip the rusulting lube into a froth, then pour off into containers. I use old bullet boxes.
: Another good lube is Lehigh Valley lube from www.trackofthewolf,com Another good lube is 50/50 mix of alcohol and murphy's oil soap, apparently.

I could be speaking way to hastily, I really need to put a lot of rounds through it to get it figgered’ out. Should get some real data tomorrow, the weather is suppose to be in the high 50’s so I’ll get a lot of shooting in.

I just can’t find the powder your speaking of here in Denver..yet. But I think your right might shoot better. I did notice that this time around the cleaning was a lot easier.
