I'm not new to black powder, been doing it for about 15yrs now, but i have a question and i hope someone can give me some ideas here. i have a 50cal thompson hawken in mint shape and with a 1-48 twist,so i will be shooting sabots with 200-240 bullets or the 245gr aerotip powerbelt bullet. can i safely shot triple seven power(not pellets) in the rifle and what max do you think i should stop at. I usually shoot 100 grains out of my other black powder rifles when i had them. Is it too hot or will i be ok if i stay at my 100 grain mark. THANKS!
