Duration: 35:24

This video details the process of zeroing a firearm, explaining the concepts of height over bore and bullet trajectory. It recommends a 100-yard zero for beginners for simplicity and demonstrates using specialized targets for precise adjustments. The guide also covers shooting stability, MOA calculations, and specific considerations for zeroing pistol red dots, while noting factors that can affect zero.

Quick Summary

A 100-yard zero is recommended for beginners as it simplifies aiming by primarily requiring hold-overs for distances beyond 100 yards, eliminating the need for hold-unders at closer ranges. Understanding height over bore and MOA adjustments is crucial for accurate zeroing.

Frequently Asked Questions

What is the best zero distance for beginners?

For beginners, a 100-yard zero is often recommended. This simplifies aiming because you typically only need to account for bullet drop (hold-overs) at distances beyond 100 yards, avoiding the need for hold-unders at closer ranges.

How does height over bore affect zeroing?

Height over bore is the distance between your optic's centerline and the barrel's centerline. Since your sights travel in a straight line and bullets follow an arc, zeroing is the process of finding the specific distance where these two paths intersect.

What is MOA and how is it used for sight adjustments?

MOA stands for Minute of Angle. One MOA is roughly one inch of adjustment at 100 yards. Knowing your sight's MOA per click allows you to calculate how many clicks are needed to move your point of impact to match your point of aim.

What factors can cause a firearm's zero to shift?

Several factors can shift your zero, including using different ammunition types (especially varying grain weights), attaching a suppressor which can alter barrel harmonics, or even just remounting an optic after removing it.
