Factory supplied 2-piece Weaver-style scope bases? If so, try removing the bases and rotating them 180 degrees and see if that changes anything. The factory supplied bases are made from extruded aluminum and I've seen quite a few over the years where the mounting holes were off-center. They should have a number stamped on one side, so the easiest thing to do first is make sure they're both mounted with the number stamping on the same side of the rifle. Easy enough to check before taking the trouble to send back to Savage.
