I thought I would throw my $0.02 in the ring. After tinkering with rifles for 40 years I would place my bets on two things. 1. Bedding 2. Muzzle crown.
Especially #1 after what you have mentioned in your posts. Remington 700's are very easy to pillar bed with the kits that are out there now. Do it yourself or have someone do it. Then shoot the rifle. If still no go, then have the muzzle crowned.
If not those two things, then it must be a bad chamber which is highly unlikely and would be visible and would be covered by warranty.
all the best, dxr
