"Brian10956"The way I did it is I took an approximately 4’x8’ piece of a large cardboard box side from an appliance store garbage pile. Set it up at 100 yards with a 4” bullseye on it mounted my scope with the rings on rifle and made sure the the cross hairs were not jacked up or down , it was 4 turns from top to bottom so I set it at 1.5 turns from bottom to start, so I wouldn’t have to worry about having enough up left in the knob when doing fine adjusting. Slightly loosened both mount then raised rear mount about 80% up the tightened both with front at lowest. Then I looked through scope and shot cardboard aiming at 4” circle I was high by a foot or so, so I raised rear mount by another 10% to 90% up then I was right on height wise for 100 yards did som fine adjustments with knobs, I then moved target to 50 yards to see how many dots below cross hairs would be my 50 ‘ aim point then the same at 150 and 200 to see how many dots to see how many dots above cross hairs would be aim point at those distances.
Wouldn't raising the rear of the scope make it shoot even higher? The new point of aim (reticle center) would now be lower than your target so you would have to pull the gun up higher to get back on target, hence shooting higher. I shimmed a scope not too long ago and shimmed the wrong end. DUH
