Took to the range to sight in and that is where my problem started.
This is a very sharp shooting rifle with good hand loads. The problem and what I noticed is that if I make no turret corrections I am getting .2-.6 accuracy Sounds great right?
However when I make a turret change lets say down 1 moa I might get down 2 moa and 1 moa right. Or maybe make a turret cange of left 1/2 moa and get 1 1/2 left and 1 moa up. I can't believe it's the scope. It was just inspected the 18th of October and a change to horizontal should not effect verticle and the oppisite is true. What really throws me is that if no changes are made to the turret it will drive tacks so it don't make since that the mount or rings are loose. Can yal help me? What is up with this? Thank's, Brad
Brad I'd say pull it off and lap the rings.
Also something I've started doing right/wrong or neutral I don't know is when I mount my rings on the rail I leave them almost loose, not quite snug. Set my scope in them and snug down the rings lightly.
I then torque the nuts tightening the rings to the rail, before proceeding to level the scope and torque it down.
Of course if you'd do this with an alignment bar, then lap the rings, and then just drop the scope in you'd probably be money ahead in the long run.
As for the "symptoms" overall it certainly sounds like something is out of kilter pretty bad so I wouldn't do any more shooting till you get it figured out for sure.
