I started out using Pyrodex pellets, then bought a couple pounds of Triple Seven, which I liked. This past fall I found Pyrodex RS for $5/lb; so I'm going to have to like Pyrodex RS, since I've got four pounds of it. Had it to the range once; works fine. Dirtier than Triple Seven, and stinks.... but worked fine. Seem as accurate, but I suspect either powder is more consistent than I am.
