Chamber is too deep - Faxon Firearms 350 Legend Gunner Nitrited Barrel

I bought this barrel in November of 2025 as I was collecting parts for a build. It takes be a while to collect all the pieces for a build as I have to limit how much I spend or I would just go crazy. I am A huge fan of Faxon and own many of their products and haven't had a problem until now. I finally got all the parts to build out the gun and begin the process of tuning and refining the parts before Cerakoting. First function test failure to fire , failure to extract. It was chewing the rim off of the cartridges, not getting a full bite and leaving a feint light strike. Called it a day and came back later with 5 different types of ammo and someone to help observations and brainstorming. (my engineer son) Still the same issues intermittently, Hornady match at least fired, but still failure to extract. So I threw a Faxon match grade BCG in from my blackout to see if it was a head spacing problem, still the same issue. The round appears to be too deep when in battery and only grabs half the rim on extraction which causes it to slip off. Aside from the fact that it is to far away from the bolt face for a proper primer strike. 1 in 5 rounds would go off and none would extract, I had to use a brass rod to poke them out. The cartridge wasn't crazy tight or seemingly deformed. I am terribly disappointed and I'm not sure if I should buy another Faxon barrel. This is my 12th build and all of my builds have gottento functioning and reliable rifles. Unfortunately I am way past the grace period for returning the barrel so it's a very expensive baton now.
