Quick Summary

To sight in a rifle scope, begin by bore sighting at 25 yards by aligning the scope crosshairs with the rifle bore's aim point. Then, fire a shot and adjust the scope turrets to match the bullet hole. For a 300-yard zero, aim for two inches high at 100 yards.

Frequently Asked Questions

What is the first step in sighting in a rifle scope?

The first step is bore sighting at 25 yards. With the bolt removed, look through the bore to center the bullseye. Without moving the rifle, adjust the scope's crosshairs to match the center of the target.

How do you adjust a scope after the first shot?

After firing one shot at 25 yards, keep the rifle still and turn the scope turrets to move the crosshairs directly onto the actual bullet hole. Fire again to verify the adjustment.

What is the recommended zeroing distance for a rifle scope?

Start with bore sighting at 25 yards, then move to 100 yards for final zeroing. For a 300-yard effective range, adjust elevation to impact two inches above the center at 100 yards.

How can I bore sight a semi-automatic rifle like a Ruger 10/22?

For rifles where you cannot see through the bore, use a laser bore sighter like the Site Lite SL-500. Align the laser with the target at 25 yards, then proceed to zero at 50 yards for rimfire.
