Can I Fix This ????

Well said. You are a good and wise man.

And the seller sounds like good folk also.

I'm still the dissenting voice. Those 2 surfaces may have been polished a little during the "blueprinting" process.

Pull the firing pin assembly, leave the barrel attached. The bolt should fall from gravity. If it does, you are fixing the wrong problem. This is a 2 minute test you should do.

Edit: I was unable to see on my phone (picture management issue) that he had already done this test. I now agree that there is a problem with the dimensions of the tenon and bolt nose recess.

You can easily check for a general idea of bolt nose clearance yourself with scotch tape. One surface at a time. Scotch tape usually runs in the 2 thou range. You can put a piece on the bolt nose with a stripped bolt, cut around the edges, you'll end up with a round piece of tape covering the nose and over the bolt face recess. Keep applying until the bolt won't close or starts to drag. Don't force it. Measure the tape when you reach this point. Will give you a good idea of bolt nose clearance. Should be around 0.010" give or take a few. Can do the same thing on the outside of the bolt ahead of the lugs. Wrap a single piece around and keep going till it drags. Measure the tape. Same thing with a FL sized case. Apply tape till it drags. You should be able to get one possible two pieces of tape on the case till it starts to drag depending on how thick your tape is.

That being said, this will give you an idea and isn't an exact measurement. It is still suggested to have it checked by a guy you trust. If it's already gone to a smith, no worries, they'll figure it out.

If I Iowned that rifle, I could fix the bolt clearance issues in about twenty minutes; including removing the stock. Whether or not this would fix the inaccuracy, I can't say. I don't think so but would be happy to be wrong. WH

@Willie, was the root cause of the issue determined?

Got a dial indicator? If the bolt has any fore and aft movement on an empty chamber, it's not hitting there. The indicator will tell you how much clearance is there, if any. Pull the fp assembly first, then see if there is any detectable movement.
Counterpart id is a little different but the bolt and counterpart will show interference if it's rubbing. Some dykem or magic marker will help. If you can pull the bbl, just do some measuring too.
Same with the front of the lugs.
Rubbing while empty is normal but not when loaded. There are only two surfaces on the action that keep the bolt from going forward..the bbl and or the bolt notch.

This was 3 years ago, haha. Sorry I never finished it.

Sent the rifle to Clayton at WTO, he does all my work. I believe he faced the barrel, bolt and lugs, but I've slept since then. The seller paid for the repairs (a good guy) The result was shooting 120 Noslers in
.2-.3" at 100 yards. My grandson is fully enjoying it.

I would be very surprised if the bartlein barrel itself was the issue.how good the chamber is cut is questionable.i would take the barrel off and measure bolt nose clearance e.t.c.if one works of Dave Tooleys dimensions on Rem 700s you won't go far wrong.i do all my 700s that way..cut the chamber spot on and accurate rifles is the norm.
