In the past I used Leupold rings and bases and had two sets of rear rings shear off that little tab the side screw tightens to. They were both installed using the alignment tool and then lapped.
I have a set of Warne mounts on a Nightforce 20moa rail and have not had a single issue with them. I noticed when I went from the 1" scope to the Nightforce 8-32x56 that is now on it was when all the problems started. I thought the scope had problems but it was all ring related.
I defintely agree with the comment to not use two piece bases, especially in a large caliber heavy kicker.
seem to make a huge difference in the scope mounting hardware also. It seems that the two actions of the recoil of the rifle and the action of the muzzle brake
to stop the recoil causes two directional forces of movement at almost the same time.
I can't prove this but my brother has the same setup as I but not a muzzle brake. He has not had a single problem with scope mounting.
Sort of strange that your scope twisted in both directions. I would expect it would only go one way. Same rest set up on both days?
Just something to think about.
