Like I said, don't force it.
This is what happens when you wreck the last .40S&W case in the push-thru resizer last night, don't notice because it's the last one, and try to do another one the next day. It takes a fair amount of force to get a Glocked case through the die, but a little more will give your case beer can-like properties.
I used equal measures of hammer, punch, and swearing to get them out.
The good news is the primer pockets are still good, and I think between trimming and the case cleaner I can load them.
