Lows will work fine, the savage barrel at the chamber end is only 1.055" or 1.120". Depending on whether it ias large or small shank receiver . Most 1 piece"tactical" type bases add enough height to make low(.25" from top of rail to bottom of scope tube) rings work with 50 mm obj scopes, with room to spare. The Bushnell OD on a 50mm is alot bigger then say the OD of a loopy 50mm. I have a setup like boiler, and there is clearance for butler creeks too. On a Remington that has a 1.20 or 1.25" OD at the chamber end, ring height is alittle more critical, measurement is required to avoid having to ship back rings. I agree with boiler on cutting off a little off the rail that over hangs the nut. Make sure the front screw doesn't bottom out on the barrel threads when u put the rail on.
