Was the rifle drilled and tapped by a 'smith?
Are the holes in the correct location?

I imagine we got guys here who know exactly, but my vague memory has it that Leupold bases have a pair of screws which allows sideways adjustment...Rear base, anyway.
So, if this is the case, loosen up on the right side and tighten on the left. (The axis of the scope is pointing to the right of the axis of the barrel. I usually gotta draw lines on paper to figure this out.)
First, find the center for the crosshairs. Move all the way from right to left, counting clicks or marks or turns, whatever. Then, come back halfway. That should put the adjustments at center. Then adjust the base to at least center on the target by boresighting. You can tweak the base just a little before actually using the scope's internal adjustment.
I hope I have it correct; good luck...

Had an odd experience with a set of Leupold double dovetail rings recently. Mounted them on the rifle, and the windage was off by a pretty good amount. Just to see what would happen, I swapped the rings out front to back, and the darned thing lined up perfectly on the collomator. Don't know why, but it worked.....
The easiest solution would be a pair of Burris rings with the polymer inserts.
You can keep the bases you have and adjust the non-concentric inserts to fix the windage issue without any gunsmithing or permanent modifications. (Although I would want the holes drilled out and aligned if it was my rifle, eventually.)

If all else fails, forget the quick release and get a set of Millet Angle Lock rings. They are windage adjustable and very sturdy.

Swap the rings, front to rear, not the bases.

Millet's are fine, but stay away from the Leopold STD rings which are also windage adjustable. They will take a beating under heavy recoil.
The scope and rings are not properly centering on the bases.
I am not familiar with the Leupold quick release bases but there should be some centering adjustment on them.
You may need to have a gunsmith align and lap the rings onto the bases to center the scope.

Properly installed, Leu std rings and bases will handle the toughest of recoi (up to and including Rigbys)l under the touhgest of conditions.
The foregoing is based on personal experience with say maybe 2000 mountings...

Did you use the Leupold "Post type" or "cross slot type" bases and rings? It doesn't look like there is any adjustability built into these bases and rings. Art's post above might be the only answer.
You might give Leupold a call and see if any of the bases and rings have been returned for out of spec. problems after checking that it is not the rifle.

My mileage was not the same. 7 STW hammered two sets into oblivion. I lapped the second set. I have a very heavy scope and this magnifies any problems with base/ring weaknesses.
The rear ring is only secured by the windage screws and I found the contact area under the screws to be soft. If there is any scope movement at all, the rear STD ring will be damaged.
