Just blew the dust off a big batch of 9mms I was cleaning for a friend and found one 9 nested into a .40S&W case.
That .40 was "glopped" and will NEVER be reloaded, at least not at my loading bench. I have several 40s so I am concerned with these damaged cases.
I bought a couple thousand "once fired" 40s a few months back, and while sizing these cases, found a very few that were glopped. These cases are suitable only for scrap!!!!!!!!!!!
Brass that has had that amount of stress in a critical part of the case should be relegated to the scrap brass bucket.
If you have a barrel that causes this damage to fired cases, glop or not, buy a new barrel.
But as said earlier, the Original Poster has NO problem, at least with the brass shown.
