But when I was in high school I learned an important lesson. Never handload with friends distracting you. We used to shoot a lot of trap after school and after a loading session as described, I got a double charge in my dad's Winchester Model 12 pump gun. I got the bird but the recoil spun me 1/2 way around. The action was locked up and ruined. I was lucky, no injuries. Gunsmith had to open the action. I could read the headstamp on the boltface. Made an impression on us impressionable kids.
