Cayugad has just told you a good way of doing that.

If you don't boresight it, then try shooting a 25 yard target. If it prints, shoot 2 more shots, (if it doesn't bore-sight it). Find the center. See how this center relates to dead center and1/2" high. Since a click is 1/4" at 100 yards,for every 1/2" at 25 yards you need to move the group, adjust 8 clicks (4 clicks for a 1/4 adjustment at 25 yards). So if you are 3 inches low, adjust48 clickshigher. If you are a1 1/2 in. right, adust 24 clicks left. Test the next shot to make sure you clicked the right way. You should be good to go out further for adjustments at greater range. If there is a crosswind, don't adjust your windage at 50 yards or more, wait for a calm day to do that.

Just remember, as you adjust, that you are moving center of a group when you make adjustments.
