I posted this before on the big bore forum. At the last Reno 1000yrd FCSA match. We had four incidents of CCI-35 primers failing catastrophically, plasma torching the bolts and blowing out the extractor on two Mcmillan actions. The primers failed at the cup edges, not at the firing pin hole!!!. 500 primers were in
a box with the lot number J22E ( nearly impossible to read). Upon very close inspection approx 6% of the remaining primers showed evidence of cracks running down the entire side of the cup. This is EXTREMELY Dangerous. A article will be written for VHP soon detailing this situation. CCI has been unavailable for comment. I strongly suggest you inspect each and every CCI-35 primer before deceiding to use it.-Rob

Thanks for the warning, I got a similar problem with CCI LR BR two years ago, fortunately in 7/08 Remington but still remember the hot gases near my eye, fortunately protected..

Happened twice on 1000 rounds of the same lot of primers when I was using the last 100 rounds.
