Im going back to tuning one or at most 2 guns at the time, I tried 4 yesterday, 3 after scope change.
I got the 52'std mod 70 in Swift shooting good after finding out the front single screw that holds ring to base was loose.Elevation was dead on but windage would wonder 2 in left or right. Easy Fix.
very best
