So I am looking to see what everyones thoughts are on extractor marks on the headstamp of the rifle brass. I have a load that seems to get an extractor mark on the head stamp area of the case. The bolt lifts without any pressure. The load is accurate what would you guys do? Shoot it reduce the load?

Cartridge gun action load data etc would help a lot. A photo of several of the case heads would help.
300 WSM on a rem 700 action. B&C stock. Hornady brass, 2.855" COAL, 165 TTSX, RL-17 67.9gr, 215M primer

Ejector marks, not extractor marks.
Is the chamber clean & dry on firing?
My mistake, yes the chamber is dry and clean has never been in the elements.

If you were to measure your fired cases from those I would expect them to show some expansion in the web area of the case based on what your picture shows of primers and ejector marks.
