REcently picked up a Ruger Old Army Stainless. This is my first attempt at blackpowder. I've been reading some posts here, and seen some good info. What I'm wondering is, what do I need to have to shoot it and to clean it. Specifically, what type of powder, accessories (measure/wads/balls/etc). A fella had mentioned Buckhorn, I believe and said it was the best to shoot in terms of non-corrosive, and I'd love to hear your opinions on that too. Any good info would be greatly appreciated. Thanks!
