Help needed with creased cases

Racingsnake · April 11, 2011, 06:09 AM

I loaded up some copper coated 158gr 38 specials last night. Most were fine but a few buckled and creased the cases when seated - see photographs below. I put a generous 'bell' on each case. What could have caused this and are they safe to shoot?

Over crimp. Back off on your crimp. I load some pretty hot 357s and don’t put that much on them.
If you need a heavy crimp you need to size your cases all to the same length.
Longer cases will crimp harder and deeper than short cases.

Way to much crimp, at the most you should crimp just enough to be able to see the crimp. I would shoot them in my 357 mag. though.

+1 on too much crimp. The good news is, they'll straighten out when you shoot em.
