Do you have another scope that is known to be good you can swap out to eliminate the scope as the problem?

If not, set the gun up on the shooting bench and secure it. Remove the bolt and look down the bore, adjusting the set up until your bore is pointing exactly at the targets bullseye at 50 yds. Then without moving the gun, look into the scope. With the turrets at center, you should be pretty close to centered on the target. If not, start looking for reasons why not. It is not uncommon for Savage's to drill the scope mount holes off axis with the barrel. Leupold rings have a windage adjustment just for this purpose and that is what was put on my 12BVSS 223 to start.

However elevation is another matter. Since you'll never need 20 moa of down turret, it makes sense to set the scope/rings so that you all the up travel the scope has to offer.

One other question: Is it possible your rail is actually a 20 moa rail and not 0 moa? Mistakes get made, so measure carefully front and back. If it's canted, it's not 0 moa.

Change rings, change rail, change scope until you find the problem. BTW: That's a very good shooting model. Enjoy it thoroughly!
