What is MOA? Minute of Angle Explained for Long-Range Shooting | Ryan Cleckner

This guide breaks down the concept of Minute of Angle (MOA) for long-range shooting, as explained by former special operations sniper Ryan Cleckner. It covers how MOA translates from an angular measurement to a linear distance at various ranges and provides practical methods for calculating and applying adjustments to hit targets accurately at extended distances. Understanding MOA is crucial for precision shooting.

Quick Summary

MOA stands for Minute of Angle, an angular measurement where 1 MOA is 1/60th of a degree. For shooting, 1 MOA approximates 1 inch at 100 yards, scaling linearly with distance (e.g., 6 inches at 600 yards). This concept is vital for calculating precise scope adjustments in long-range shooting.

Frequently Asked Questions

What is Minute of Angle (MOA) in shooting?

MOA stands for Minute of Angle. It's an angular measurement where 1 MOA is 1/60th of a degree. In practical terms for shooting, 1 MOA typically translates to about 1 inch at 100 yards, scaling up proportionally with distance.

How does MOA relate to distance in long-range shooting?

MOA is an angular measurement, so its linear size changes with distance. While 1 MOA is roughly 1 inch at 100 yards, it becomes approximately 2 inches at 200 yards, 3 inches at 300 yards, and so on. This scaling is crucial for accurate adjustments.

How do you apply MOA adjustments for long-range shots?

Think in 'chunks' based on distance. For example, at 600 yards, 1 MOA is about 6 inches. If your shot is 12 inches low, you need to adjust your scope up by 2 MOA (12 inches / 6 inches per MOA).

Why is zeroing at 100 yards important for long-range shooting?

Zeroing at 100 yards is standard because it simplifies adjustments for longer distances. Most subsequent corrections will be 'up' adjustments, making it easier to manage trajectory compensation as the bullet drops.
