I'm almost certain that the extractor is inhibiting the cartridge rim to slide up the breech face. They say to tweak it with a small screwdriver blade to slightly loosen it up. I may polish a little on the bottom inside of the claw as well, just as you would with a 1911 extractor. From the looks of the bind, that is where the problem is. I'll wait until my trigger gets here and do all at once.
