I had the same thing happen with a .300wm rem 700 LR a couple of years ago and spoke to a lot of folks on here about it. I had a smith cast the chamber, measure headspace, & I even polished the chamber. The problem wouldn't go away. Every piece of fired brass from that rifle had a shiny spot just above the belt on one side. It even had a measurable bulge.
So then I decided to rebarrel it. That's when my smith found the cause of the problem. When the threads in the receiver were cut to accept the barrel, they weren't cut square to the receiver itself. I wound up having to scrap the receiver and the barrel.
The smith did try to salvage the receiver by cleaning up the threads but by the time he got it back square there wasn't enough thread left to safely engage the threads on the barrel and it wouldn't get tight. So basically the bolt face and the chamber weren't completely aligned and that caused the sticking cases.
It was an expensive lesson to learn but now I have an even better rifle so that's cool I guess
