I am presently working on one of those.................thing's. As it came, accuracy with anything was non-existant. I've tried both win and rem factory loads, Hornady 75 gr v-max and Nosler 70 gr ballistic tips. I've tried 3031, IMR 4350, BLC/2, win 748 and varget. I've used CCI200, Win WLR and Herter 120 primer's. Win, Rem, and LC Match cases. Nothing work's!
Now I've removed that uplift in the forend, relieved the whole action, opened up the recoil lug mortice and epoxy bedded it with micro-bed compound. The reciever now drop's right into place, there's no pressure anywhere on the barrel, the action touches only where the reciever bolts come thru, the screw holding the front of the trigger guard (plastic), I tighten down snug then backed off about a half turn (I may take it out and glue the trigger guard in) and the barrel is also bedded for about an inch and a half in front of the reciever.
Tomorrow I'm going back out to see if any of this helped. My impression is that Remington is selling these things with a semi-inletted stock! Even after relieving the recoil lug at the front and side's, the action area still grabbed the reciever and it took the screws to pull it down!
Reading back, the area under the front and rear reciever screw's is epoxy bedded also. The recoil lug make's full contact at the rear and is free at the side's and front.
This is my last Remington!!!!!!!!!!!!
