Easy zeroing the scope
First, place a paper target on the backstop at about 10 yards and take a shot at its center. Remove the dust covers from the windage and elevation turrets of the scope and make adjustments as necessary to the turret to bring the point of impact (POI) closer to the point of aim (POA).
A high impact point requires a clockwise adjustment. Both turrets move the POA a 1/2 minute of angle per click – this is equal to a 1/2 inch at 100 yards or a 1/20th of an inch at 10 yards.
Once achieving an approximate zero at 10 yards, move back to a measured 20 yards and continue adjusting the turrets until the top cross of the reticle and the point of impact are the same. At this range each click equals 1/10th of an inch.
Shoot a three-shot group at your target and adjust until your reticle and groups are aligned when you are happy with the 20 yard zero, replace the turret covers.
