I haven't shot real black powder since the early '70's. I had a cap and ball revolver that I shot a lot of it in. When I was older and bought my first bp rifle, the store that I got my bp from had closed, and the LGS didn't carry real black. Pyrodex was the choice so I went with it and have had no problems......until now. I bought a drop in Green Mountain 54 cal slow twist barrel for my T/C Hawken and it will give fairly frequent hang fires with both 777 and Pyrodex. I was thinking that if I go to real black powder, these will probably stop. I know I'm gonna have to get it online but didn't know where was the best place. I've seen it at Powder Valley. I knew that y'all would know the best (cheapest) place.
