[QUOTE="Dean2, post: 1956239, member: 26077"] You could be right about the chamber, but firing three rounds of new brass with a load 1 grain above min will give him a perfect chamber cast. Once he measures those it will be easy to tell if it is chamber/headspace or too hot a factory load. I always figure, work from the simplest to the more complicated. Far more likely to be hot loads than a bad chamber on a fairly expensive semi custom rifle. That said, current measurements and the picture of the once fired brass does show some pretty big expansion and bad stretch on the case just ahead of the belt.. [/QUOTE]
