When posting this, I somehow lost a lot of the content, so attempting to edit it now.... I have a Rem 700 .30-06, and I'm wondering when to retire the brass. With the load my rifle likes, I am seeing light extractor marks occasionally, and slightly cratered primers regularly. I never have bolt lift stiffness. I'm shooting Barnes 168 grain TTSX, 50.0 grains IMR 4064, Rem 9.5 primers, and Lapua brass. Bullets jump 0.050 inches. I'm up to 7 loadings on some of the brass, and while I've never seen any of the lightening of the brass on the exterior above the web, I was getting paranoid, so I sectioned a couple cases that I've fired 7 times as well as one that I've fired only 3 times to compare. Would you be concerned by this? Might there be a rapid onset of a problem above the web (or anywhere) even though I'm not seeing signs of thinning at this point? Thanks for any advise you might have. Feeling like I need to back off of this load and run a new ladder test.
