Short and simple. I have been loading 9mm with some bulleseye i found localy. Pistol powders are few and far bettwen around here so i was looking at using what i have to start loading for a 1911 i have recently aquired. I have load data for the powder in question but i was wondering about the suitablilty of the powder for the cartridge. I know its good for the 9 due to the quick burn rate but not so sure about the lower pressure 45 any experence or advice is appreciated
