I've had one casehead separation in the years I've been reloading, and that was with a .280 Rem. case that I had been loading and using first in my old 725 Rem, as I wanted to see how many deer I could kill with the same case. Ya gotta understand this was years ago when I was a much younger and foolish guy, never giving a thought to the aftermath of a case body stuck in the chamber or the like. Just like death and taxes, it happened. If I remember right, it was on the 9th loading of that case.

Anyhow, I now toss 'em after 5 loadings. I used to try the paper clip trick too, with varying amounts of success. I don't bother looking for stress crack signs anymore, now that I've been taught how to count to five...
