Paul, I load BP on my Mec Jr. I know many guys say not to because of static electricity, but I've been doing it for years with no problem and when I ask if anyone knows of someone who's had a problem no one can answer. Anyways, a 46 bushing throws about 70grs [ by volume - the way BP is measured ]. You can deprime, prime, add powder with the machine or by hand if you're worried about using the machine, add wads and shot with machine, and then crimp or take it off and roll crimp. If you're fold crimping use a 6 point start die - or if previously crimped use a smooth start die [ which Mec sells ]. I've also cut off a 46 bushing to get 84grs, or don't use any bushing to get 94grs. In my Layman BP Handbook they list for 2F with a 1oz load and paper wads anywhere from 75grs to 102grs which gets from 1079 to 1442FPS. For 1 1/8oz the same powder and wads gets from 1017 to 1353FPS. That 70grs of 3F would be about the same as 85grs of 2F for pressure and velocity. You can load BP with a lot less worry about how much is used. All those loads were below 6000LUP [ or about 7000PSI ]. I would think about 75grs of 3F will get about 1200 to 1250FPS - a nice clays load.
