Also, I heard that the wolf gold brass cases had a coating that would stick in the chamber.
Nope.
This was actually with domestically (US Midwest) produced ammo using wolf gold new brass. A buddy bought 300 rounds and was ripping rims with his extractor if he left an unfired round in a hot chamber.
I've shot a few cases of Wolf brass and I never had any problems with it. I don't do anything to it but give it a VLD chamfer with a Giraud trimmer. It's some of the best brass out there for 5.56.
I'd bet $$ to donuts the problem was with the loader.
