I’m fairly new to reloading about 6 months in with mostly hand gun & 12ga Trap shooting. 380, 38 Spcl, 9mm, 40 S&W, 12ga Winchester AA shotgun. I bought 1k 380 95 gr RMR bullets and thought I’ll try some of these in 9mm & 9mm load data using Lee Modern Reloading data book. I kept getting failure to eject jams in almost every clip. Not sure why, never tried it again. I’d think the Longshot powder would give plenty of power for ejecting and feeding ?
