[QUOTE="mechengr, post: 1993779, member: 75894"] I have some 280 Rem brass by Hornady that looks exactly like that, I thought it was case head separation at first too but couldn't feel anything using a hooked wire inside the case. Just been shooting them and no issues thus far, and no changes to the cases' condition since the first firing with 3 firings on some of them now. I now think it's just my chamber and that batch of brass must have been on opposite ends of SAAMI tolerance . That region is right where the case web thins to meet the case wall so on first firing the wall is going to expand to fill the chamber but the thicker web section won't expand as much which give the slight bump on the outside of the case. So long as you don't bump headspace too much when resizing from here on out you should be good to go. [/QUOTE]
