I use to load 4 oz of shot and 400 grs of 1f in a 8ga O/U muzzleloader I made. Think I was way over loaded.
Theres a fellow who built himself a 20mm muzzleloader which is about a 8bore
20mm is .825 , he proof tested with 1000grs of 1F the twist rate on them is for a 1760gr slug or around that . that works out to 1/4lb or the same weight as a 4 gauge/bore round ball .
Charlie have you ever loaded blackhorn 209 ? Its supposedly pretty clean and doesnt really foul like BP or the other substitutes on the market .
