I have several Savage rifles. I do not bed the barrel nut, for two reasons. First. I change barrels and can't be sure the barrel nut will always be in the same position. Second, the grooves in the barrel nut could make a mechanical lock.
I bed the recoil lug back to the front action screw, then again from the rear of the magazine to the rear action screw. I prep with a little PlayDoh in the corners of the magazine, in the front action screw hole, and at the tab in the rear of the recoil lug. Recently, I have been using the rear action srew and pantyhose tied around the stock and front ring to hold it as it cures.
