[QUOTE="lancetkenyon, post: 1578203, member: 68875"] Have you checked the headspace of the Rem vs Federal brass with a gauge? I know in most 7RM brass I have found, regardless of the brand, have a LOT of headspace difference between new and once fired. Usually, something like 2.104" for virgin to 2.123". Then, I bump the shoulder back to 2.121" when I FL size. Check your brass to see if that is the case. I am wondering if the chamber the brass was originally shot in was just a touch longer than yours, and if you are bumping your shoulder back far enough. Also, if you have fired any of the new brass, what the difference is to your Rem brass. [/QUOTE]
