I've been having so much fun shooting mouse fart loads in my 38spl, I want to load some in 9mm and see how I like shooting them. My guns all have factory springs which I'm not willing to change, so the loads will have to function at least a stock G19. What I'd like to know is some of your favorite powders for powder puff 9mm loads with 147gr bullets. I'm using plated, so if you shoot lead or jacketed, just let me know so I can extrapolate. I have BE, TB, WSF, 2400, Unique, and WST. Very interested in if someone has any data for BE or WST. And of course I'm willing to buy other powders as well. Really I just want a light 147gr round. It's easy to find WSF data, but I'd like to try a faster powder. I'll be chrono'ing these rounds when I test them.
