Ok, I started shooting some reloads that I whipped up. 6.7 grains of No.7 under a 115 FMJ bullet for 9mm and they failed to eject all the way. They would jam up after every shot. Checked OAL and it was fine. Switched to some reloaded JHP and no feeding problems at all (except for 1 where I forgot to seat a primer). Before I pull them all any ideas what happened? Not enough powder? People I was shooting with said that it may be too much powder.
