[QUOTE="FearNoWind, post: 975989, member: 50867"] I believe your scope has a little over 90 MOA adjustment, top to bottom. 45 up - 45 down from center. With your reticle centered and a 20 MOA rail you should easily have 65 MOA of adjustment available. That would, of course, take you into the area of the glass that is less than perfect. Roll your elevation turret to the bottom. Turn it up 20 MOA and see if it will bore sight at that setting. Then see where it shoots. Unless you've got that 20 MOA rail on backwards you should be about five or ten inches high at 100 yards. Maybe a little more, maybe a little less. But I'd expect you to be on paper. If you're not on paper, find a small target (piece of stick, small weed, etc.) in the berm and have someone watch through a spotting scope and have them tell you what your error is. Adjust the scope to correct the error, record the adjustment, and determine where in the range of adjustment you are when you're on target. That way you'll know precisely how much adjustment you have for come up at long range. If you can't get enough elevation (45+20=60 MOA x 10 = about 600 inches at 1K) out your set up with that method you've either got a scope that missed quality control before it left the factory or they sent you the wrong rail.
