Case head sep

Just got done checking 760 rounds of 223/556 for CHS. How often do you guys find cases about to separate? I hear I'll know when I feel one with a paper clip but so far nothing.

Head separation primarily occurs with bottleneck cases. You should be able to get 5-10 reloads before any signs unless you are over working the shoulders or are reloading very hot.

It’s been my experience that cases split or primer pockets get blown out long before any case head separation occurs. I guess that if you have excessive head space it may occur more often in auto/semi-auto weapons. The last, and only, case head separations I’ve ever had was with a Browning 1919A4 many years ago, caused by improper head space adjustment. I never check cases for it anymore.
