Understanding Minute of Angle (MOA) | Long-Range Rifle Shooting with Ryan Cleckner

Understanding Minute of Angle (MOA) is crucial for accurate long-range shooting. MOA is an angular measurement, approximately 1 inch at 100 yards, that increases linearly with distance. This concept simplifies scope adjustments for bullet drop and windage, allowing shooters to precisely compensate for gravity's effect on trajectory. Proper zeroing and understanding scope click values are key to achieving consistent accuracy.

Quick Summary

Minute of Angle (MOA) is an angular measurement, 1/60th of a degree, equating to roughly 1.047 inches at 100 yards. This value increases with distance, allowing shooters to calculate precise scope adjustments for bullet drop and windage.

Frequently Asked Questions

What is Minute of Angle (MOA) in shooting?

Minute of Angle (MOA) is an angular measurement where 1 MOA equals 1/60th of a degree. In practical terms for shooting, 1 MOA is approximately 1 inch at 100 yards, increasing linearly with distance (e.g., 2 inches at 200 yards).

How does MOA relate to bullet drop?

MOA is used to compensate for bullet drop caused by gravity. By understanding the bullet's trajectory and the MOA value at a specific distance, shooters can adjust their scope to aim higher and hit the target accurately.

How do I calculate scope adjustments using MOA?

First, determine the value of 1 MOA at your target's distance. For example, at 400 yards, 1 MOA equals 4 inches. If your shot is 8 inches low, you need to adjust your scope up by 2 MOA (8 inches / 4 inches per MOA).

What are common scope click values for MOA adjustments?

Most hunting and many precision rifle scopes use 1/4 MOA click values. This means four clicks of the adjustment turret equal 1 MOA. Always confirm your scope's specific click value.
