wow, did this thread ever blow up overnight! anyway Klem, the 300blk case that did my barrel in was a converted wolf .223 case. I think I mic'd the neck of the fired case at .014-.015 after the failure if I remember right. I don't know where the little bugger got to, but I started neck turning all my converted brass after that to .012 and haven't had an issue since.
originally, I suspected a double charge, but with the ridiculous amount of bullet down in the case, there's no way I would have been able to fit that much powder in there.
but I digress...we're talking about grendel brass failure here, and I've never had one of those.
