Band of marks around brass.


Recommended Posts

What manufacturer/brand is on the headstamp?

What was posted above is pretty much on, but I did recently find one brand of 9mm case with a crimp line that really bulged out on loading a 147 moly bullet. The bulge happened right at the crimp line, and was bad enough that most of the rounds would not chamber in a factory Glock chamber.

Kachik: That must have been some cannelure on the brass.

Do you have photos of the pre-loading case internal appearance?

After firing, the cannelure is "inside out" with the inside walls no longer having the cannelure sticking into the case.

Of course, you could "solve" the problem with a Lee FCD.
