Thread: What happened ????

+1 for looking at the Hornady brass. I loaded 7mm rem mag cases and one separated after only a few firings. Lucky I noticed it when I was giving the rounds a polish after loading so avoided a nasty surprise! The other cases seemed fine so guessing one weak one. I binned the lot anyway to be sure. Primer pockets were not great for tightness compared to Norma which I changed to. In fact if I hadn't of found the separating case they were due to be discarded after the next firing for that reason.

I am with you mate, I got 60 rounds to go, one failure so been a trill seeker once I have these 60 shot off they are going in the bin.

Whats your neck tension like, could this projectile have slipped in a bit further, giving a "compressed " load ? I know that ya case is going to be pretty full anyway but maybe that gave a higher pressure when jumping to the lands?
