Savage bolt action receivers are made from relatively soft, ductile metal which doesn't have a lot of spring temper in it. The rails are very thin and flimsy. Two bolts hold the action to the factory pillars, with the tang bolt being well ahead of the end of the tang. Under recoil, the action bucks, arching up between the receiver rings and pushing the tip of the tang downward. If the tang is bedded, the action flex stretches the threads of the rear action screw. If the nut or any part of the barrel is bedded, it stretches the threads of the front action screw. The only places to bed a 11X or a 1X Savage action is in the immediate proximity of the pillars, behind the recoil lug, and along both sides of the recoil lug. The bottom and front of the lug need have clearance because it frets up and down during the firing cycle.
