I'm curious if the powder capacity of later Southern horns (and Eastern horns in general), say in the 1830s, was less than for the Long Hunters and the trappers? My reasoning is the hunters didn't go very far from home, their cabin on the hill. So they would only need a few shots, when out for a day or two, and it would save weight. The pocket horns I see come to mind. I just made my first 2 horns, both ended up being small, which is fine for me....I do the same thing - refill them at home.
