GPO USA 6-24x50 Passion 4X Riflescope (MOA Ballistic Reticle) - Manual (Page 30)

Windage side adjustment
The PASSION™ 4X riflescopes are equipped with turrets that will
adjust your bullet point of impact by a ¼ MOA (¼”) or 0.7 cm
at 100 meters with every click. If you want to zero this riflescope,
please do the following:
1. At a shooting range fire a group of 3 shots at the center of a
target that is 100 meters away. These 3 shots create a bullet
“group” and it is the center of this group that will need to be
adjusted to the center of the target. Best is to not make indi-
vidual turret adjustment after every shot, since individual shot
placements can vary. Adjusting the “group” to center adjusts
the average to center, so individual shots outside the average
group do not cause you to over/under adjust the scope.
2. Estimate where the center of the “group” is on the target.
3. Unscrew the cap of the windage (side) turret. If the center of
the group is 2 cm to the right of the center line of the target,
then the group needs to be adjusted left (windage) 2 cm. 1 click
will move the group ¼” at 100 meters, so 8 clicks will move
the group 2” at 100 meters. Adjust the turret in the specified
direction you want the bullet group to move.
4. Repeat 3 shot group procedure to ensure proper group windage
placement on the target.
