Case that had blown primer possible safety issue

[TheGerman]

Had a virgin 308WIN case blow a primer during load development last week. When fired, there was a bit more smoke then usual, the rifle felt different and the primer came completely out of the case. Other than that, nothing bad.

Just came across this case again after tumbeling, FL sizing and cleaning out the primer pockets. When I went to seat the primer with an RCBS hand priming tool it was noticeably easier to go in. Upon inspection, the ring you see between the primer and the end of the primer pocket is also visually larger. The primer does not come out and is seated the same depth as the others it seems.

Question. Is it safe, or at least not prone to get the primer blown out again because its somehow been altered by the high pressure? Or just toss it?

Toss it. Not worth the risk of a repeated failure.

I would toss it.. Your bolt face will agree.lol

The gap around the new seated primer shows how the pocket was deformed by the venting gas that blew the first primer. Definitely a throwaway, and data on what not to do next time.

Yeah data I have lol

No signs of pressure at .5 below that load and first one at the higher charge does it.

Tossed it, not screwing around with it.

Did you try any others at that .5 higher grain weight? What primers are you using? Was your bullet jammed or jumped? How sticky was the bolt lift? Depending on your answers to some of those questions, you may have reached a max load for the bullet/powder combo. I have had some load work where a .5 change in the charge weight would show pressure, where the load prior showed none. Usually it was a combination of really hot weather and a powder that was not as temp stable as Varget or 4350. Defiantly toss that piece of brass.

As a KABOOM survivor, you made the right choice. I was fire-lapping my Glock 22 (.40 S&W) after having a gunsmith replace the barrel with a fully supported KKM, and failed to read the directions which clearly told me to lower the charge. I was firing 10 and cleaning the barrel. I started to notice that I could no longer read the headstamp on my Starline brass. Bad sign, but I went merrily on in my ignorance. Afterall, I had survived 30 with the highest abrasive bullets, I only had 20 more which were basically polishing the bore. Then KABOOM. They say that any crash you can walk away from is a good landing. I still have all my fingers and both eyes, so I would say that it was a cheap lesson (it totaled the Glock) Split the chamber of the KKM on two sides, and peeled the top of the slide back half an inch like a banana. THAT will make a believer of ya!
