Headspace gauge for 308 vs Nato

[Patrick Chadwick]

How about 7.62x51 fired in 30-06 chambers? Seen that one more than once. No sign of head separation, but no neck at all, just a nice "crimp".

I have been on the firing point next to someone who did just that. He was not a regular shooter at my club, but a guest who had hardly fired a full-bore rifle before, and had one on loan. I heard him complaining loudly about the rounds being hard to chamber and the accuracy being awful. I looked across to see what he was moaning about, and as soon as I saw the neckless cases I stopped him on the spot, and made sure he returned the rifle and cartridges to their owner! With the appropriate comments!
