I've shot some black, and a lot of Pyrodex, using a mag primer and a felt wad. It seems odd to use the wad under a hollow base bullet, but I found it improved accuracy, and minimized fouling. I've got about 100 still loaded, and when those are gone I'll go only smokeless. I've had to break down the frame twice already to clean fouling there, and I'm just too dang lazy.
(The bullet side of the wad was lubed with bore butter.)
