Today I was running Dot Torture WITH my Gen 4 Glock 17 and Independence aluminum cased 115 grain FMJ.
I had a round which felt hotter than normal so I stopped and saw this stoppage:
Apparently the round was hot enough to pop the primer and knock the anvil loose from the primer cup.
Even the "normal" spent case and primer show flow back into the firing pin hole.
I've shot over 1k of this ammo without issue. I've heard of pooped primers with ZQI and Fiocchi 9mm - has any one else experienced this issue with Independence ammo?
