I got a shell stuck in a reloading die.. it sheared the rim off when I tried to withdraw the press. No idea why but no matter what I did, including actually cutting the case in half lengthwise would get it to budge. Could it have actually welded to the die?
I hate when that happens... Brass is soft, you can chisel it out, otherwise replace the die.
Doubtful. Did you use lube?
That would be my question as well. I have used too much lube on some 7.62X54R cases and ruined them with dents... they were nice Lapua cases too.
