Hello,
I load for my Gew88. Cases are formed from .30-06 into 7.92x57J using modified dies. The bullets are 0.318" as that's what my bore slugs at.
I noticed I had several out-of-round loads this last go-around. Don't remember it happening before. Had something like 12 out of 50.
I neck sized last time and so I disassembled the cases to their components and full-length sized five of them. Out of those five, one was still out-of-round.
I'm really not sure what's going on. The press is a Lyman turret -- the older orange one -- and the dies are Lee. I load the 7.62x54R using the same equipment and Lee dies. There are no out-of-round loads for that round.
Since the 7.92x57J is relatively straight wall, should I even be trying to neck size with a full-length sizing die?
What are the causes of out-of-round cases, anyway? I don't think I ever learned that...
Thanks!
Josh
