If both have the accutrigger then yes it is the same. When Savage went to the Accutrigger they changed from a flat top rear receiver to one that was round like the front. Newer savages have the same round front and rear receiver mounting. The spacing and hole spacing is the same in the 10 and 11. You may want to think about using a two piece mount however, while heat treating, the actions warp slightly, so you may fine you have to put a little stress on a one piece mount to get the screw holes to line up.
