Roskoe there is a powder on the market called BlackHorn 209. It will shoot in your Genesis with a good hot primer, but not in your black diamond. You can shoot this stuff all day and never have to swab. It also is some real powerful stuff. A lot of people like it. Some do not like it. I tried it in my Genesis and it worked real good. But the best powder in my Genese so far has been Pyrodex RS Pellets of all things.
