GPO USA 6-24x50 Passion 4X Riflescope (MOA Ballistic Reticle) - Manual (Page 28)

Elevation top 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 tar-
get that is 100 meter 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 individual turret
adjustments 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 elevation turret. If the center of the
group is 2 cm below the center line of the target, then the
group needs to be adjusted up (elevation) 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.
Repeat 3 shot group procedure to ensure proper group elevation
placement on the target.
