You would think I would have run across this before. Maybe but not this obvious. Everybody is at Camp Perry except me so I'll pose this question here. I have been shooting a FN SCAR 17s. During my last range trip I took my Moe's gauge to check case expansion of my handloads. Most of them measures between 3 and 5, a couple measured 6. This was LC 07 that had been re sized to 0. I also had shot about 300 rds of W German surplus MEN 94 DAG 94 and DAG 68. Prior to firing most of the W German stuff measured 0 on the gauge.After firing none of the W German stuff would fully seat into the Moe's gauge. At first I thought the case at the web had expanded due to the chamber being 7.62X51 NATO. But closer exam I noted the base of the case neck to have an area of expansion that was probably the culprit. The pics show this. I have included , 3 cases 2 fired one not. Left is the LC 07 and LC 90 Match handload, the right is the W German DAG 94. It is berdan primed so I am not going to reload it , but the difference in the cases, and that they won't enter the Moe's gauge fully, concerns me a little. There are no other signs of pressure. The W German Ammo is really very accurate and has proved SD's in the single digits out of my Scout. Sooooo is this the result of a 7.62x51 NATO chamber being a tad bigger in the front end? And My gauge being a .308 Win.
