I don't have any experience with the Talley mounts. The dozen or so AccuTrigger models (12/112 BVSS or 10LE2B) I have used Weaver Grand Slam bases (S46) on have not had this problem. This has been over the last six months with two being in the last three weeks. Are tops of the receiver (front & rear) the same height from the bore centerline? Are the mounting holes inline with the bore and top center of the receiver? Are the rifle serial numbers close enough to possibly be from the same casting/machining run?
More help may be available from "Mr Furious" and "SAS" at the Savage Shooters Forum, or Savage Customer Service. Good Luck ... Mike
