[QUOTE="jdavistx, post: 1959436, member: 89418"] I took a simplistic view. 6.25MOA high (a 5' POI adjustment, independent of all other variables) @ 900 yards. If you think you are adjusting MOA but actually MRAD, it seems to be a big difference at POI. Your analysis looks thoughtful and I'll try and replicate what you did. Thank you. I tried to apply the tracking test concepts at 900 yards. The final answer lies with the OP after he does a standard scope tracking test at 100 yards. Zero is set to 100 yards, adjust up 10 MOA (everything else being the same), the shot will be a 10.5" high for MOA vs 14.4" high for MRAD. If the scope is incorrectly built, there will be a 4" difference between expected and actual results. Should only take 1 shot after zero is set to see if it's the issue. [/QUOTE]
