For my rebuild from 338 to 270, I'm nixing the savage 2 pc. rail mounts and rings and getting the EGW 1pc rail @ 0MOA. My scope was so restricted in positions in which it could be mounted, I notice that from recoil, the rear base is a bit peened from the rear ocular that sat so close. I'm pretty excited about the 1 pc. and for the price, it can't be beat, it seems. Nice to have a flat back older LA 116 for this purpose, the EGW 1 pc. is cheaper than for the newer models. As fgw_in_fl notes, you could just dremel out the center of the 1 pc. and convert it to a 2 pc., but that sort of defeats the purpose of the 1 pc. base, as it contributes to accuracy; but it might not matter much depending on your scenario, i.e. range of your shots. Good luck.
