now that I have "conquered" 45acp, 38 special, and 357 magnums, meaning I have made rounds, fired those rounds, and gun and fingers are all in 1 piece, LOL. my new challenge is a 45 long colt for a rifle. Will be shooting a modern Henry Rifle, with a 250g bullet. Question is, What is best performing rifle powder and at what grain charge, or since this is technically a pistol round, should I stay with a pistol powder? I would think that a rifle powder should be just fine, but since I don't know, and this forum has plenty of experience, all inputs appreciated. Target shooting is the primary application for these loads.
