OK, I'll try again.
The recoil lug / action face is probably not true to the OUTSIDE or inside of the action.
Even a trued action can have the lug off a little bit from the OUTSIDE of the action, although it will be trued where it counts and that is the bolt bore center.
The lug being off a little will not be fixed by Remington. It is something that just is on a factory rifle PERIOD.
bedding it will correct this, at least in the way it sits in the stock. The bedding material will be between the aluminum where the recoil lug sits and will make it a solid resting place for the lug even if the lug is off a bit.
This is the only fix short of what I have said in prior posts.
Your faith in the HS stocks bedding block is far too much. They too are not perfect and would not have an HS stock on a rifle that was not bedded PERIOD.
I have seen bedding blocks crooked in the stocks. The ones that where ran for Weatherby awhile back where notorious for that. Got not a few replacement stocks from Weatherby when the problem was fixed.
Like I said, even though advetrtised as drop in and interchangable, they are not, not if you want optimum accuracy.
49 out of 50 times I bed an HS stock the rifle will shoot a little bit better. It ranges from as an example 5/8 groups to 1/2" groups at the least. It corrects the "flyers" caused by your same problem
A rifle is a system of parts that needs to be ever so carefully blended in with one another to make a great shooter.
Drop in is just not viable.
You will find this problem in most factory rifles. It is not just limited to Remington.
If you want a perfect rifle system, you have to get a custom built by a good rifle smith.
