Sully, your in luck. After a week vacation I'm back!
Yes Talley mounts for a savage (round back) will work.
Or the two front base lupy's as mentioned.
Or for $35 more from Stiller you can get a 0 MOA (flat) base. Then through $65 more on it & get a most excellent set of TPS picatinny rings (I also have seekins, badger, MKIV, & for the price I like TPS best). You'll be grades ahead.
When I got my first stiller I was not interested in the picatinny rail either but thought what the heck (price was going to be similar regardless). Went picatinny rings & base verses the tried & true 2 peice Leupold rings/base I had always used. Well, now years later, about all my serious stuff has picatiny ring/basse. Best out there, you can't beat it off with a hammer!
Give them a try. It will only cost a few more $$$ than a different aproach. It will not disappoint!
If you still don't want to give it a try, I've got MANY sets of used Lupy rings & bases. I've even got a set of lupy style (actually burris brand) rings & bases for M12 savage (also stiller pred) you can have cheap!
