I think she burns a little dirty
My 45 ACP is a pretty rugged gun(Ruger P90) but it always seems to get REALLY nasty after firing 20-30 rounds loaded with AA No. 7. And after 60 or so rounds pulling the slide feels really gritty and Ive never had this problem before
I just recently started doing my own reloading and bought the No. 7 because theres quite a bit of leeway between the Min and Max amounts of powder to use. And since 9.9gr fills up the cartridge pretty well it would be impossible to double charge and not notice.
But yah, next time im going to try either the IMR 800x or Win 231
