No issues. Haven't even shot a box with this new scope and rifle has only had about 26 rounds through it.
Just been researching and bedded my one piece rail and made sure the rail was straight. Picture the rings being attached to a rail and then flexing the rail up in the middle or down in the middle. This will put the rings out of alignment with each other. This in turn will put pressure on scope.
There are four places have to be perfect to be torque free. The top of rifle machined perfect. The rail perfect to the rifle. The rail to the rings and then the rings to the scope.
Just thought I would try it. One guy said he bedded his twelve years ago and has never had to mess with it since and he shoots out to 1000.
