OOPS! Just lube it a bit an run it through yer 9mm sizing die, no problem...

 

[Dudedog]

To bad it's not a .40 then it could be fixed with one of those bulge busters.

Call to techsupport
" But the die just does not seem to remove the bulge like it's supposed to"

No issues, those cases just need "tummy tuck" operation.

I have picked up brass fired in a larger chamber. For example, finding 40 S&W fired in a 45 ACP is rare but not unknown. The forward part of the case beyond the web is expanded to the larger size. Back in the day a local shooter had a problem with an open bolt 9mm MAC. Turns out the 9mm had a 380 chamber. Wonder if measuring the non-bulged portion of the case would give you a clue on what happened? That round went off and was "fire formed" in a chamber of some sort.

9mm Parabelly?

 

[Mowgli Terry]

Reverse rebated case?

9mm Parabelly?

You did not go there! The rare and elusive 9mm Parabelly also know as 9mm Parabellyium.

This brass looks just like the guys photos on the main discussion page with his AR-9.
