How to Zero In a Scope on a Rifle: A Comprehensive Guide

What is Zeroing a Scope?

Zeroing a scope, also known as sight-in or calibration, is the process of aligning the rifle’s scope with the barrel’s point of impact. This ensures that the scope’s reticle (the pattern of lines or dots in the scope’s glass) is accurately aligned with the rifle’s bullet trajectory. In other words, zeroing a scope means adjusting the scope’s settings to match the rifle’s accuracy, so that the bullet hits the target at the expected point of impact.

Why Zero a Scope?

Zeroing a scope is essential for accurate shooting. Here are some reasons why:

• Consistency: A zeroed scope ensures consistent shot placement, which is critical for hunting, competition, or tactical applications.
• Accuracy: Zeroing a scope helps you hit your target with greater accuracy, as the scope’s reticle is aligned with the rifle’s barrel.
• Efficiency: A zeroed scope saves time and effort, as you won’t need to spend hours adjusting the scope or rifle to achieve accuracy.

Step-by-Step Guide to Zeroing a Scope

Pre-Zeroing Checklist

Before you start zeroing your scope, make sure to:

• Check the rifle’s accuracy: Ensure the rifle is functioning correctly and accurately shooting at various distances.
• Inspect the scope: Verify the scope is properly installed and all adjustments are functioning smoothly.
• Choose a suitable target: Select a target with a clear view of the shot group (the pattern of bullet holes).
• Determine the zero distance: Decide on the distance at which you want to zero the scope.

Step 1: Establish a Reference Point

• Set up the target: Place the target at the chosen distance from the shooter.
• Shoot a group: Fire 3-5 shots at the target, using the same ammunition and rifle settings.
• Measure the group: Record the center-to-center (C2C) measurement of the shot group. This will be your reference point.

Step 2: Adjust the Scope

• Elevation adjustment: Adjust the scope’s elevation knob up or down to center the reticle over the shot group. Make small adjustments (1/4 MOA or 1/4 cm) and re-shoot after each adjustment.
• Windage adjustment: Adjust the scope’s windage knob left or right to center the reticle over the shot group. Make small adjustments (1/4 MOA or 1/4 cm) and re-shoot after each adjustment.

Step 3: Confirm the Zero

• Shoot another group: Fire 3-5 shots at the target, using the same ammunition and rifle settings.
• Verify the group: Measure the center-to-center (C2C) distance of the new shot group. If it’s close to the reference point, you’ve achieved a zeroed scope.

Tips and Tricks

• Use a laser bore sight: A laser bore sight can help you quickly establish a reference point and make adjustments more efficiently.
• Shoot in the same conditions: Zero your scope in the same conditions (weather, light, and distance) you plan to use it in.
• Use a scope level: A scope level ensures the scope is properly leveled, which is critical for accurate shooting.
• Take your time: Zeroing a scope requires patience and attention to detail. Take your time to ensure accurate adjustments.
