The other alternative for us laypersons is to use Burris Signature rings with their offset insert kit, windage or elevation corrections can be made with the inserts to perfectly align the scope with centered reticle with the bore or to the desired amount for elevation for long range shooting, then fine adjustments are made with the turrets at sight-in. They're real popular for 200yd rimfire matches just for fun too!! /ubbthreads/images/graemlins/grinning-smiley-006.gif

Signature Pos-Align® Offset Insert Kit
Signature Rings also accept Pos-Align Offset Inserts so you can virtually sight-in your gun without moving the scope adjustments. Lens systems perform at their optimum when all lenses are optically centered. By keeping the internal optics centered, you'll see through the scope all of the clarity, sharpness, and brightness that the optics designers intended for you to see. The offset inserts also correct for any mis-alignment caused by receiver holes drilled off center, or the bases or rings being slightly off perfect center. And for you 1000 yard and other long range shooters, the need for expensive tapered bases or shimming becomes a hassle and expense of the past.
