I just got me a Sightron 10-50x60 to replace the SWFA 16x42 on my 110 custom build. I have a one piece 20 MOA mount that I used with the SWFA and Weaver tactical medium height rings. The problem is when I'm bore sighting I don't have enough adjustment to bring the crosshairs up over the target. They are also way too right. I called sightron they said it is a mounting problem. I mentioned that my SWFA worked fine on the same mount and he stated that the high magnification of the sightron was the issue. "But I set it to 10x I replied." He still insists that the high magnification somehow exaggerates the error of the mounting.

Can't really wrap my head around this one. I suppose it is possible that the 20 MOA inclination of the mount is beyond the range of the scope to adjust, but not too sure about the windage issue.

Any ideas?
