The range I go to is in the country and has a tactical course, when I’m out there if I see a interesting shell in the misfire bucket I’ll take it and put it on the wall of my workshop. Bottom left is a 44 long colt that the guy shoved so far into the casing it became a mini grenade, and he was trying to fire it when the owner stopped him. The 7.62x39 above it is almost as bad.
