[QUOTE="Sierra1wardog, post: 1627175, member: 103466"] Check and compare pre and fired case dimensions. Measure multiple points including the web, headspace, neck and length. I am not familiar with your rifle or cartridge but I have read about cases showing similar signs because of excessive expansion. Not related to over pressure issues but from a smaller case expanding in a larger chamber and slamming back into the bolt face. Maybe even both brass and chamber are within Sami tolerances but at the extreme edges and you are just seeing the effects of your virgin brass expanding and flowing to fill the larger headspace?
