I recently purchased 100 rounds of supposedly once fired 308 brass at a gun show. The brass is all marked "LC 06". I sized it all in a Hornady sizing die and trimmed it all to length. Upon trimming the brass I notice that it all seemed a little long for once fired brass. Some of it was up to 25 mils too long. Anywho.........after the cases were all preped I loaded them with the same powder charge (46.5 gr H380) as my previous loads and capped them off with 150gr Hornady SSTs (the same load I've been shooting for months). When I got to the bench I noticed that NONE of the Lake City cases would chamber in my rifle. They seem to go into the chamber well enough but I can't lock the bolt. I've inspected all of the brass by measuring length and diameter but, I can't seem to find any differences between the Lake City and the Frontier brass that I've been using.

Do you have any idea what the problem my be? Have you heard of anyone else having problems with Lake City brass?

Hope this ain't a hijack..

I always check the head of my LC brass for "extreme" stretching with a paper clip; it's easy to see the stretch marks on the outside of the case head, but it's even faster and easier to feel it than look for it. I say that to pose this--I've never trimmed and full-sized any brass that didn't fit the chamber it was sized for after that process--isn't that the reason and purpose of a full-length sizing die?

That is to say, wouldn't a full-length die resize even full-auto brass "properly" to the right dimensions (assuming the trimming was done), and fit in the chamber, even though the case wall was dangerously stretched?
