- Set Magnification: Start at 3x (low magnification). It is easier to find the target.
- Fire a 3-shot group: Shoot at a target from a steady rest (bench or sandbags). Don't worry about hitting the bullseye yet; just see where the bullets land.
- Measure: Let's say your bullets hit 4 inches Low and 2 inches Right.
- Adjust:
Step 2: The Positioning Rule
The manual states that the scope should be positioned so you have a full field of view when you mount the rifle naturally. Set Magnification: Start at 3x (low magnification)
Eye Relief: Set your scope magnification to its highest power (9x) and mount the scope loosely in its rings. Slide the scope forward or backward until you see a full field of view without any black "halos" or "donuts" around the edges. Repeat until groups are centered
Bore Sighting: Start by aligning the scope with the barrel at 25 yards to ensure you are "on paper." Windage and Elevation: Use the capped adjustment turrets. 1 Click = 1/4 MOA (approximately 1/4 inch at 100 yards).
- Repeat until groups are centered. Confirm at desired zero distance.
