Out to the range today and ol' Reliable let me down, huge. I picked up a battlepack of pmc ammo on the way. I can rack a round into the chamber and fire it and then I get a failure to extract, a 2nd round feed and of course a jam. I clear the jam and it happens again consistantly. Last time I had this rifle out it was flawless and always has been.

Nothing has changed with this firearm in years. I tried numerous mags today and the problem continued. The same mags worked well in other rifles today.
I pulled the bolt and nothing is broken, the extractor seems to have good tension, the hook or claw seems okay, carrier key seems fine.
What's up? Is a bolt rebuild on order? Will a new spring fix my problem, or is it something else?

Any help is appreciated.
