I can help you out and take that power pistol off your hands. I have loaded about a pound worth of it with my Hornady measure for 9mm , no problems. 4.4-4.6 a throw consistantly, and that's without the pistol drum, just the original drum and meter that came with it.I may try to reload some 9mm with 231 and see if the charges are more consistent - but then won't know what to do with almost 4 pounds of Power Pistol !
