This 9mm looks like a belted magnum. This is one of my reloads.
Does your resizing die seat against the shell plate properly? It looks as if it doesn’t get to the bottom of the case.
I’ll save my deleted post for the joke thread
Can’t explain this one
I have crunched a few cases, but I haven’t encountered that.
Yeah i would think if it did this in resizing it would have not ran through the other stations.
I agree, since the rim looks deformed.
I’ve had similar issue before. Both instances the case was overstretched and i didn’t measure and trim it.
It was too long and you didn’t trim to length. Sizing die did that.
Seems reasonable. I never take the time to trim straight wall pistol cases.
That’s what I would think. The only place this can happen is in the sizer or seater.
Do you run a seating/crimping die by chance? You could have a roll crimp set up wrong
I run a separate crimp die
Is that range pickup brass?
Ok. It could have been fired in something like a 40 S&W, fire formed to that chamber. Resizing to 9mm wouldn’t iron out all the deformation. Mic the bulged area. Is it about .425", maybe more?
I’m going to pull the bullet later and I’ll post pics of the inside.
I think so too now that you pointed that out. Be interesting to see the thickness of the case wall. Maybe case length too.
The case is buldged inside the case almost like it was fired out of battery.
This is the downside to reloading on a progressive. Wish i new what this case looked like before i loaded it.
