Bet you have more respect for those old timey buffalo hunters now.
The thing is they usually were wearing a lot more that we were Saturday with the hot humid weather. I think the smartest thing for me is to go to a rebarrel in something like 38-55 or 40-70. I'd hate to end up with this beauty on the wall without being able to handle it.
I'm not sure about the light bullets as I don't know just how light a 1:18 twist would stabilize say a 375 gr bullet or a bit over.
