[QUOTE="Ward Thurman, post: 1578146, member: 109209"] Hello all. I am Ward Thurman, long time reloader for my sons bountiful hunting (usually). We recently purchased a used M77 in 338 Win Mag. This is our first belted magnum. We also bought some used Remington brass and after I loaded them up, they would not allow the bolt to close. We bought some Federal factory loads too and they went through the gun perfectly. After much dinking around with the Remington brass, I shaved some of the top of the belt off and wal-la, they went into the chamber. So my question is, is the belt groove in the gun machined wrong or is the brass out of spec? We measured the base to top of shoulder an it was 0.215 while the Federal was about 0.210. The book lists that dimension as 0.220. I hate to throw away the brass, but are we doomed to finding the perfect brass to fit this rifle or is there a fix? Tks so much! [/QUOTE]
