Thanks for all the info guys! I'll be doing some research and trying to check out all of the suggestions.

And I've mentioned this before, check that the ejector pushes back at least flush with the bolt face. If its hanging up short it drags on the casehead and can also cause stiff bolt lift on fired brass. It may or may not leave a 90* rub mark on the casehead.

I checked the rear screw on the front scope mount, it doesn't seem to protrude into the lug recess. However, the ejector pin looks like it's not quite flush with the bolt face. I looked at a couple of spent cartridges and noticed a spot on most where the rear rim is marred, but I'm not sure if this is normal, or if it's the 90* rub mark you are referring to. I'll see if I can get some pictures to help explain more.
