Long, long ago before all the ice melted, leaving us the Great Lakes, piles of boulders and the Chalupa thingy that sucks goats; I had to buy my powder locally one can at a time. I carried home whatever he had in the vault, 2F, 3F. I used them interchangeably in my rifle and didn't know any better. I was satisfied as long as the gun went bang at the pull of the trigger.
I actually hit some of the things I aimed at. Though it was a .58 I killed squirrels with both minie and prb (my preference). I never thought to use it for deer.
I cast ALL my ammo from scrounged lead so shooting was fairly cheap. This was good because I'm cheap, always have been. I tended to hang around weird people..........or, as I've overheard, "why do they hang around this really weird guy"? It got worse and worse so that now I have flintlocks scattered all around.
