btw...I found a T/C manuel that I was given when I taught hunters safety...a .50 cal Hawken and a 370 maxi-ball...Max is 100 grains FF black powder....777 is about 15-20% stronger than bp...So you are actually over the published limit...
Except that he's shooting a 295-grain bullet, not a 370-grain one! Big difference......
