[QUOTE="bruce_ventura, post: 640222, member: 34084"] In theory, yes, the Zeiss can get there with 42 MOA. However, manufacturing tolerances can be a problem. With 42 MOA adjustment, you don't have much room for error. You've got about 6 MOA to spare, to be precise. In a production rifle, a zero MOA base could easily be vertically mis-aligned from the bore by more than 8 MOA. You may have to shim or bed your base 10 or 20 thou to correct that error. When installing the scope, I recommend you you use an arbor boresight collimator to assess base alignment and dial in your base. I would not hesitate to do it, because the Zeiss glass is worth the effort. Alternately, if you use a mildot reticle, you can zero at 200 yds using one of the dots above the crosshairs. You can add 10 or so MOA that way. [/QUOTE]
