[QUOTE="drenge, post: 420057, member: 9300"] I've been taking a few measurements and compared against saami spec. The 7 mm rem mag should have a headspace of 2.125 and my brass is getting tight at 2.121 which means my gunsmith may not have cut the chamber deep enough. I called redding and they said their tolerances are very tight on both their shell holders (1/8 inch deep) and their dies. The comp shell holders actually start deeper than their standard shell holder (1/8) so that will not fix my problem. The only solution is: a) cut the bottom of the die down a few thou; or b) have my smith cut the chamber a little deeper. I'm inclined to have my smith cut the chamber deeper after hunting season because I am noticing a small cut along the shoulder of all of my tight fitting brass. Meaning there is some kind of imperfection along the shoulder inside my chamber. Thanks again for your help. [/QUOTE]
