So what causes this?
Primer is struck in the middle.
No signs of overpressure on the primer or the unsupported part of the case.
It was shot from a glock.
It is my reload. 5 gr unique under a 124gr PD FMJ at 1.15".
I have about 10 guys over to go shoot'n all the time. No tell'n what any of them bring over to shoot.
Notice how the brass is thicker on one side of the rim vs the cracked side.
My vote,
Bad case.
