Rifle Scopes Help Sightron SIII how to get mechanical zero?

[One_Man]

Here my situation:

Scope is mounted with Burris Signature rings and is zeroed. Problem is I have about 75 clicks windage to the left and only 25 clicks to the right. The rear mount has +0, +0 inserts and the front has offset inserts (+10 on the left, -10 on the right). So, the front of the scope is slightly skewed to the right.

I am going crazy trying to figure out how to mechanically zero my windage. Can anyone help?

Here is my crude drawing to help illustrate my problem.

You'll want to optically center your scope to effectively use your zee rings. Find the middle of the windage and elevation of the scope. Then when sighting in don't even touch your knobs, rather use the inserts to change your point impact. Burris Site has a video instruction.
