Shot my .50 BP rifle today using 3f goex. I had some trouble ramming the ball home so i went ahead and brushed the bore after every shot. That certainly made ball slip down easier. It also produced a lot of charcoal dust which then had a habit of clogging my nipple so had to pull that often as well. Fyi- i build this gun maybe 25 yrs ago as a kid and as such has seen its share of corrosion over the years. As a result the bore is not in the best condition it could (should) be in. I cannot remember needing to do this in the past shooting 2f goex and pyrodex. I use the yellow greased patches and have been using bore butter after cleaning for several years now. I know BP can be dirty and its not a big issue for me to brush every shot or two... but I've been watching a show set during the revolution and it got me thinking how those guys kept their guns running beyond the first couple shots. Later during the civil war as well.. What was the common practice when muzzle loaders were the only firearms around?
