Thanks all.

I’m trying to find a load that regulate on my Kodiak muzzleloader .58”
I know that the Kodiak it is not truly regulated, just have “some convergence”.

I shoot it only once (12 round balls and 7 REALs) from the bench. I put some sandbags over the bench and shot (on my knees) trying to keep my back straight up. Take the rifle and rest only my forward hand on the sandbags
With round balls (300gn) barrels are crossing about 2.5” at 25 meters.
With R.E.AL. bullets (440 gn) barrels are crossing about 4” at 50 meters.
Use only one owder charge, 82gn of FFFg black powder (the only I can get here).
I have to make more shooting to confirm this but I have been thinking that resting my hand too much on sandbags and or leaning forward can cause part of this crossing. That’s why I consider using sticks.

Thanks for your advises, I learn a lot here.
I will try just shooting off the bench.

Thanks
Martin
