Re: Bases and rings!
Unless I am mistaken, your scope has a 30mm main tube, so you'll need rings that are 30mm. Vortex has a couple different style rings of which I prefer the precision matched rings. These particular rings are manufactured for Vortex by Seekins Precision, who also sells the same exact style rings from him web site. Compare prices and availability from different places and they'll be about the same.
As for a scope base, I'm not as familiar with Savage actions. I would suggest using a picatinny spec rail but this isn't completely necessary, you might be able to find a two-piece base set-up out there somewhere. In either case, I'm almost positive you'll need a 20 MOA base with that scope to get the .308 out to 1K.
So in a nut shell, my suggestion would be to find a one piece 20 MOA picatinny rail that'll fit your action and then find some 30mm rings that will attach to a picatinny spec rail. This isn't the only option, just my personal suggestion. We have some of the Vortex rings in stock for the 30mm scopes if you are interested.
