AMERC brass strikes again

[Dux-R-Us]

somewhere I picked up a couple AMERC pieces of 9mm brass. They caused a real headache; jammed pistol.
You can see the AMERC brass (left) is undersized because the 147 gr bullet bulged it when seated. The other round is a "normal" FC case. So I am checking all my brass very carefully now for any AMERC stuff.

Looks like it's time for a case gauge. We case gauge every round, pistol and rifle. It doesn't really add that much time to the process and comparing to everything else we spend money on they aren't that expensive.
