Depending on how old your Savage is, it will either have a "flat" rear on the receiver top, or a round one. You will see mounts described as "round rear" or "flat rear" to designate which era of Savage receiver they fit. The "round rear" is the current model Savage receiver, and is likely the one you need?
I have Warne brand 1 piece bases on 2 of my Savage rifles. These are the "tactical" base and ring sets offered by Warne. They are made of steel and are of very good quality. I'm using one in a "0 MOA" configuration, and one is a "20 MOA" base. If you're going to shoot real long range, say 600 yards and farther out, get the 20 MOA base. If you're going to only shoot 500 yards and closer, the 0 MOA base should be fine. The difference is the 20 MOA base is canted, to add additional elevation to your scope for distance shooting.
I hope that answered your question?
