How to Sight in a Rifle Scope for 100 Yards

Sighting in a rifle scope is a crucial step in ensuring accurate and reliable shooting. Whether you’re a seasoned hunter or a recreational shooter, a well-sighted-in rifle scope is essential for achieving optimal performance. In this article, we’ll guide you through the process of sighting in a rifle scope for 100 yards.

Before You Begin

Before you start sighting in your rifle scope, make sure you have the following:

• A rifle with a scope attached
• A target or a known distance marker
• A shooting bench or a stable shooting position
• A chronograph or a range finder (optional)
• Ammunition with a known ballistic coefficient and velocity

Step 1: Zero the Scope

Zeroing the scope is the process of aligning the scope’s reticle with the rifle’s bore. This is usually done by adjusting the scope’s elevation and windage turrets.

• Elevation Adjustment: Loosen the elevation turret and adjust it clockwise to raise the point of impact or counterclockwise to lower it. Make sure to adjust the turret in small increments (1/4 MOA or 1/4 click) to avoid over-adjusting.
• Windage Adjustment: Loosen the windage turret and adjust it clockwise to move the point of impact to the right or counterclockwise to move it to the left. Again, make sure to adjust in small increments.

Step 2: Determine Your Point of Impact

• Use a Target or Known Distance Marker: Set up a target or known distance marker at 100 yards. This will allow you to accurately measure the distance between the point of aim and the point of impact.
• Shoot and Observe: Fire a shot and observe where the bullet impacts the target. Take note of the distance between the point of aim and the point of impact.

• Elevation Adjustment: If the point of impact is above the point of aim, adjust the elevation turret counterclockwise to lower the point of impact. If the point of impact is below the point of aim, adjust the elevation turret clockwise to raise the point of impact.
• Windage Adjustment: If the point of impact is to the left of the point of aim, adjust the windage turret clockwise to move the point of impact to the right. If the point of impact is to the right of the point of aim, adjust the windage turret counterclockwise to move the point of impact to the left.

Step 4: Verify and Refine

• Shoot and Observe Again: Fire another shot and observe where the bullet impacts the target. If the point of impact is still not at the point of aim, repeat the adjustment process.
• Verify and Refine: Continue to adjust and verify the point of impact until it is within 1-2 inches of the point of aim.

Additional Tips and Considerations

• Use a Chronograph or Range Finder: If you have a chronograph or range finder, use it to measure the velocity and distance of your shots. This can help you refine your adjustments and ensure a more accurate shot.
• Use Ammunition with a Known Ballistic Coefficient and Velocity: Using ammunition with a known ballistic coefficient and velocity can help you make more accurate adjustments and ensure a more consistent shot.
• Keep a Shooting Log: Keep a shooting log to track your adjustments and verify your point of impact. This can help you identify patterns and make adjustments more easily.
• Practice and Patience: Sighting in a rifle scope requires practice and patience. Don’t rush the process and take your time to make adjustments and verify the point of impact.

Conclusion

Sighting in a rifle scope for 100 yards is a process that requires patience, practice, and attention to detail. By following the steps outlined in this article, you can ensure a well-sighted-in rifle scope that will provide you with accurate and reliable shooting. Remember to use a target or known distance marker, adjust the scope in small increments, and verify and refine your point of impact. With practice and patience, you’ll be able to achieve optimal performance from your rifle scope.
