Duration: 17:42

This guide explains the essential steps for zeroing a rifle, emphasizing the importance of boresighting before live fire. It details how to make initial scope adjustments, take precise shots, and use reticle measurements (MOA/Mil) to correct for elevation and windage. The process highlights understanding scope turrets and reticle subtensions for accurate zeroing, ultimately saving ammunition and ensuring safe shooting practices.

Quick Summary

Before zeroing a rifle, boresight it by aligning the barrel with the target and roughly matching the scope's reticle. This ensures your first shot is on paper. Then, take a shot, measure the impact's deviation from your aim point using your reticle (MOA/Mil), and adjust the scope's turrets accordingly, one correction at a time.

Frequently Asked Questions

What is the first step before zeroing a rifle?

The crucial first step before live-fire zeroing is boresighting. This involves looking down the rifle's barrel and aligning it with your target, then adjusting your scope's reticle to roughly match this alignment. This ensures your first shot is on paper, saving ammunition and time.

How do you make adjustments to a rifle scope for zeroing?

After taking a shot, use your reticle's hash marks (MOA or Mil) to measure the impact's distance from your aiming point. Then, adjust the scope's elevation and windage turrets accordingly, typically one at a time, to bring the impact to your point of aim.

What is the difference between MOA and Mil adjustments on a rifle scope?

MOA (Minute of Angle) and Mil (Milliradian) are different angular measurement systems used for scope adjustments and reticle subtensions. MOA is roughly 1/60th of a degree, while a Mil is 1/1000th of a radian. Understanding which system your scope uses is vital for accurate corrections.

Why is it important to understand your scope's reticle when zeroing?

Your scope's reticle provides a reference for measuring the distance between your point of aim and point of impact. Knowing the subtensions (e.g., how many Mils or MOA each hash mark represents) allows you to calculate the precise number of clicks needed on your turrets for correction.

How do you confirm a rifle's zero after making adjustments?

After making adjustments, take another shot at the same aiming point. Ideally, the impact should be very close to your point of aim. For maximum confidence, confirm the zero with a cold barrel after the rifle has cooled down completely.
