100% of my brass that has reached it's final loading has failed just above the web, that place where the sizing die stops. This batch was in need of shoulder bumping, but it still chambered, just a little bit tight, but none of the brass was on it's last leg though. I don't usually load brass that chambers that tight without having first bumped it, so I am now thinking that was why it did, what it did.
I was shooting a 700 SPS 7mm RM loaded with 120 gr. V-Max and 69.0 grs. of RL22, a well worked up and tested load I've been shooting for some time now. The few rounds that didn't chamber as tight against the shoulders didn't fracture. Nothing leaked and no gases blew through at all, and everything functioned normal with no pressures issues or stiff extraction.
Is this typical of shoulders that need bumping?
