2. Shoot at Every Goal

Hearth a bunch of pictures at every goal distance, aiming on the heart of the bullseye. Observe the purpose of influence (POI) for every group of pictures.

3. Calculate the Correction

Decide the vertical and horizontal offset between the POI and the supposed level of goal (POA) for every distance. This offset will point out the correction required to zero your scope at that distance.

4. Make Scope Changes

Utilizing the scope’s adjustment turrets, make changes primarily based on the calculated correction. For instance, if the POI is 2 inches low at 200 yards, you’d regulate the elevation turret to boost the POI by 2 inches. Equally, if the POI is 1 inch left at 300 yards, you’d regulate the windage turret to maneuver the POI 1 inch to the correct.

5. Confirm the Zero

After making the required changes, hearth one other group of pictures at every goal distance to confirm the brand new zero. If the POI continues to be not aligned with the POA, repeat the method of calculating corrections and making changes till you obtain the specified zero in any respect distances inside your supposed vary.

Distance (yards) Vertical Correction (inches) Horizontal Correction (inches)
100 0 0
200 +2 -1
300 +4 -2
