The knuckles of my left hand hurt for a week after shooting, I need a glove with a padded back. Once I forgot my powder measure and use a empty 45acp case, figured it held 20 grains so I put 3 cases full of T7, holly mother of god, it about jumped out of my hands, got home and measured a 45 case, it held 30 grains, so I had loaded 90 grains of powder. The gun can handle even more but I can't.
