I shoot 90 grains of Goex 2f with a moose milk patched .530 roundball in my Flintlock Trade Rifle. It will shoot on average a 4 inch group consistantly. With conicals the Trade Rifle really shines. Mine loves the 405 grain Powerbelts, and the REAL conicals.

That is some nice shooting there. Glad the rifle is working out for you. They sure are a sweet rifle to shoot...
