I've been reloading since 1981, but I am relatively new to reloading .380 Auto. I'm using Hornady Custom dies and, until recently, my go-to propellant has been Winchester 231. The bullet I'm using is Hornady's 100 grain FMJ. I've loaded this box with 3.9 grains of Alliant Power Pistol, but have yet to shoot them. The firearm is a Glock 42. Anybody else have experience with Power Pistol in this caliber?
