I can understand that...What I'm shooting is a muzzleloader I built...English sporting rifle style, 1-40" twist for bullets, but it also shoots round balls very effectively with about 60 to 80 grains of 2F...
This set up was designed by a friend to shoot 120 Grains 2F, pushing a 940 grains bullet @ 1300 FPS, about 3700 lbs @ the muzzle...Already has taken a Cape Buffalo and Elephant...NEI has the mold and I will probably buy it...Just don't know how much I'll use it...Just like your story...
