Try this bolt upgrade kit. $4.95 and the right stuff. The stuff at the hardware store probably won't take the heat. G&R are great people too. They also have good deals on BCM uppers.

FYI, I totally cleaned the Bushmaster today, then took it out to the range and ran 80 of Federal 50gr. JHP's though as fast as I could... Not one hiccup.
Upon examining one of the stuck Wolf 62gr FMJ's, I could see where the extractor ripped off some of the soft steel rim from the case.... further, the primer had backed out of the primer pocket and it was flattened...
I.G., I believe you're correct on the tight chamber... I'll rerun some Wolf ammo through the Rock River (same failure to extract) and see if it has the same case after being fired as the Bushmaster.
