Resizing some 257 Roberts and encountered a neck separation I don't recall ever seeing before. 3x loaded Nosler +p brass.

I’ve had more trouble with the little bit of nosler brass giving up the ghost prematurely than ADG and Peterson combined, in many more cartridges. No visible pressure signs then releasing the primer next firing for instance.?
Just screwy, with no warning.

I had something similar years ago .

Brass Failure

I went to the range today to check out some loads that I have had setting on the bench for a while and wasn't impressed with the results so I'm not including pictures of the groups. I was testing some 225gr ABs and some 250gr PTs with RL17 and CFE223. The 250s surprised me a little since they...
