Yessir, I got it cleaned up without a Dremel. Yes, I knew the factory fired them, but I was thinking it looked like maybe just a little more than a couple rounds through it. The lack of residue forward of the feed ramp (which is relieved, as you said), and the thread compound dust in there were clues that maybe it had NOT been fired since the factory.The rifle is fired at the factory to insure it's in good working order. That's common practice for all legit firearms builders. The action is a modified Rem 700. All Remington 700's now come with 5R barrels. And the short action are modified to fit 2.950" cartridges. This is noted by the feed ramp being relived in the center to accommodate the longer cartridges. I wouldn't take a dremel to anything. I'd give it a real good cleaning and go shoot it. My new Remarms ADL 7mm RM shoot sub moa in a KRG stock. I'd just shoot yours and see how it does.

LOL ok. Well all I know is when I did it every rifle I cleared was personally test fired by me. Just in the manner I described. I even had a check list that I marked and signed. I'm not sure who you spoke with at Remington. You can post the paper trail on here if you wish.This is what Remington always claimed, fired at the factory pre-new design. Until I received two brand new in the box 700's WITH NO CHAMBERS. Not really possible to test fire a rifle without a chamber.
I pressed Remington about this, photographing the non-chamber through the receiver and their response was that due to the volume of rifles they produced, they test fired 1 rifle out of 10 rifles.
Enjoy!
