I can only relate a similar problem that I encountered with my Savage model 12 I spend nearly 9 months purchasing different mounts, trying various scopes with same issue I finally returned gun to Savage and they replaced barrel I was not given much info other then a defective barrel, when it was returned I was on target with 3 rounds and no problems since. I at first suspected mount holes were incorrect or a warped receiver. Looking back I would not have spent so much time in working to correct but simply returned to Savage.
