How to Bore Sight a Rifle

When it comes to precision shooting, bore sighting your rifle is an essential first step. Proper bore sighting saves time and ammunition while getting you closer to zeroing in your scope. Whether you're preparing for a hunt or target shooting, this guide will walk you through the process.

What is Bore Sighting?

Bore sighting is the process of aligning your rifle’s barrel (the bore) with the crosshairs of your scope. While it won't give you pinpoint accuracy, it sets the foundation for fine-tuning your scope at the range.

Tools You’ll Need:

• Your rifle

• A stable rest or bench (a bipod, sandbags, or a shooting rest works well)

• A bore sighting tool (optional but helpful)

• Your mounted scope

• A target (placed at 25-50 yards for best results)

Step-by-Step Instructions

1. Safety First:

   • Ensure your firearm is unloaded. Double-check the chamber and magazine.

   • Remove the bolt (for bolt-action rifles) to allow a clear line of sight through the barrel.

2. Secure the Rifle:

   • Place your rifle on a stable rest. A firm, immovable setup minimizes errors during the process.

3. Align the Barrel:

   • Look through the bore (the hollow tube of the barrel) and aim it at the center of your target. Adjust the rifle’s position until the target is centered when viewed through the bore.

4. Adjust the Scope:

   • Without moving the rifle, look through the scope. Use the scope’s windage (side-to-side) and elevation (up-and-down) adjustment knobs to align the crosshairs with the target’s center.

   • Repeat the process, alternating between the bore and the scope, until both are aligned.

5. Using a Bore Sighting Tool (Optional):

   • Insert the laser or magnetic bore sighter according to the manufacturer’s instructions.

   • Align the laser dot with the crosshairs on your scope. This step often speeds up the process and increases accuracy.

6. Test at the Range:

   • Once bore sighted, head to the range to fine-tune. Start at 25 yards, fire a few shots, and make the necessary adjustments to your scope until your shots consistently hit the bullseye. Gradually increase the distance to your desired zeroing range (e.g., 100 yards).

Tips for Success:

• Be Patient: Precision takes time. Small adjustments go a long way.

• Work in Good Lighting: A well-lit area ensures you can clearly see through both the bore and the scope.

• Keep Tools Handy: A multi-tool or screwdriver for scope adjustments and a cleaning kit are useful to have on hand.

Common Mistakes to Avoid:

• Skipping the Range: Bore sighting is just the first step. Always confirm and adjust at the range.

• Unstable Setup: Movement during the process can lead to poor alignment.

• Rushing: Taking your time ensures accuracy and saves ammunition later.
