I spoke with a fellow who ground his sizing die off to resize them, a 444. He used regular bullets. Some don't mess with them ( like me,ha) but others play around with them.
I thought it was just the length of the shell that was different with everything else being the same, which meant only during the crimping stage would an adjustment have to be made.
I got some sent to me with some other brass I bought for my .45/70 single shot. If you're not gonna use 'em, you could alway donate them to a guy with a single shot................... like me ;D .DT
