I was zeroing one of my 30-06 rifles yesterday that I had installed leupold scope base and rings on and at the range I ran out of scope adjustment and couldn't get the rifle to hit far enough to the right. I just loosened the rear windage screws on the mount and moved them in the direction needed and was able to zero the rifle and have adjustment left in both directions. So maybe the shooter needs to get a scope base with windage adjustments in it because there is a lot of side to side adjustment just in that part of the setup.
