Seekins, Badger, EGW and Warne all make tapered bases that fit Savage actions. As does Ken Farrell mentioned above. I have the EGW unit on my Savage and it works well for my needs.
I just got done mounting an EGW 20 MOA on my Savage 10FP that I picked from MidwayUSA for $32.99+shipping-Went right on easily-holes lined up correctly and furnished screws fit properly
