MOA Explained in 2 Minutes

This video explains the concept of Minute of Angle (MOA) as a measurement of angle, not distance. It clarifies that 1 MOA at 100 yards subtends approximately 1 inch, and this angular relationship remains constant regardless of distance, meaning the physical spread of shots doubles at 200 yards and triples at 300 yards for a 1 MOA rifle.

Quick Summary

Minute of Angle (MOA) is an angular measurement, not a direct distance. 1 MOA at 100 yards subtends approximately 1 inch. This angular constant means that the physical spread of shots from a firearm increases linearly with distance; a 1 MOA rifle will have double the group size at 200 yards and triple at 300 yards.

Frequently Asked Questions

What is Minute of Angle (MOA) in firearms?

Minute of Angle (MOA) is a unit of angular measurement used to describe firearm accuracy. It's crucial to understand that MOA measures an angle, not a fixed linear distance. One MOA at 100 yards subtends approximately one inch.

How does MOA relate to group size at different distances?

Because MOA is an angular measurement, the physical size of a shot group increases linearly with distance. A rifle with 1 MOA accuracy will have a group size that doubles at 200 yards and triples at 300 yards compared to its group size at 100 yards.

Is MOA a measurement of distance?

No, MOA is a measurement of angle. While 1 MOA is often approximated as 1 inch at 100 yards, this is a convenient relationship derived from the angle. The actual linear spread will change with distance, but the angle itself remains constant.

How many MOA are in a full circle?

A full circle is 360 degrees. Each degree is divided into 60 minutes. Therefore, a full circle contains 21,600 minutes of angle (360 degrees multiplied by 60 minutes per degree).
