Rell

Here is a suggestion, done for 2 reasons

Shoot the gun WITHOUT the scope on with your most accurate load, one that you know where it is printing on the target.
I might even suggest shoot 4 shots at the target with the scope, mark the target L1, L2, R1, R2 and then shoot 4 more shot at exactly the same Point of Aim but without the scope.

See if that makes any difference.

I would suggest using a white dot as it is easier to hold the point of aim.
