Just as a helpful point, (and you probably already know this, but I'm posting for those here who might not) Alexander Arms brass is made by Lapua, (The only difference in Lapua and AA brass is the headstamp.) Lapua brass tends to be on the extreme small side of the spec for brass, (small enough that my dies don't even resize new brass at all) while Hornady is on the top end end of the spec size wise. In fact, the Lapua brass is sized such that I have 20 firings on some of mine and have never had to trim it.
I've never heard of that difference causing this issue, but if it did, I can see where tolerance stacking MIGHT be the cause.
We look forward to hearing what you find, and appreciate you joining the board.
I definitely appreciate the info, I actually just purchased some of the new AA brass to measure the difference in the 3 cases, I don't think this is the issue either, but I know that on a 308 I have(i used 7/08 brass) and bumped the shoulder back too far and it wouldn't fire, so I want to eliminate that theory.
I promise I'll keep everyone posted, after I talk to John when we find the answers. Thanks
