I have owned a .50 cal Pedersoli Kodiak for a long time and want to hunt deer with it this season. It functions perfectly but I'm struggling to get it regulated at 50 to 100 yards. It's on paper but the barrels cross at 50 yards by 4 to 5 inches. I use 70 grains of 2F powder in my .50 percussion and flintlock single barrel rifles to great success but not so much in the double Kodiak.
I'm looking for loads using primarily .50 cal round balls but, I have a bunch of PA Conical's I'd like to try. I'm thinking about 80 plus grains of 2F. Before heading back to the range I'd like to have some suggestions for loads and bullets.
The Kodiak's barrels are in great condition, but the rifling is shallow, not worn but not deep either. The right barrel is "tighter" than the left so, could that be part of the problem? It's not much tighter and the bore condition in both barrels is great.
Any advice is appreciated,
Best to all,
Don
