Changing height of both rings will not give you more or less adjustment. Your scope is not parallel to the bore or it would have sufficient adjustment @ 100 yds.
I would put a set of Burris Signature rings on it, mounted as close to bore as is possible w/comfortable cheek weld. The Signature rings allow you to tilt the scope in order to get very close to mechanical zero on your scope.

First you need to return your scope to mechanical zero (as much adjustment up as down; left as right. In other words the reticle needs to be centered in the tube. Next, mount scope and boresight it w/reticle @ mechanical zero. This will give you full adjustment that your scope is capable of.
Since you ran out of elevation, you need to mount the scope lower at the front than at the back. Using the different thickness inserts, this is easy to achieve according to the following instructions:
Quote:These offset inserts work only in Burris Signature Rings. One insert half is slightly thicker and the other slightly thinner than standard. Swapping the standard inserts with a pair of offset inserts will move the point of impact approximately 5" at 100 yards for the .005 inserts, 10" for the .010 and 20" for the .020. This will allow a gun to be sighted in that cannot be zeroed with the available windage and elevation adjustments in the scope. For serious shooters, the optional offset inserts allow a scope to be brought almost to complete zero, then using the windage and elevation adjustments only for the final, fine adjustment. This keeps the erector tube centered in the scope for improved scope clarity and performance. Includes "zero" inserts, other Pos-Align inserts can be purchased separately.
Not only will the Signature rings correct your problem, they provide perfect scope alignment without lapping scope rings and the plastic inserts prevent scope slippage, even on high recoil rifles. I won't mount a scope in any other ring.
