Progress is being made. After talking to reps from both Remington and Winchester, rifle and ammo were shipped back to their respective makers. Received a quote from Winchester to "Place gun in proper mechanical condition" which includes replacing the bolt. Remington rep said he'd take care of the charges for the repair and a call to Winchester confirmed they received the check and are proceeding. He also said he'd send me a replacement box of ammo from their "premium line". I just got it and was kinda surprised it was a box of Barnes VOR-TX. When I asked he said the faulty ammunition dated from '98 and was corroded on the inside which led to the primer leak.
I'm happy to be reading this today!
