What is a MOA used for?

A Minute of Angle (MOA) is primarily used as a unit of measure in ballistics, particularly in relation to firearms and shooting. Specifically, MOA describes the angular measurement that correlates to a specific linear distance at a certain range. One MOA roughly equals 1.047 inches at 100 yards, which is rounded to 1 inch for simplicity in practical shooting applications. This measurement is critical for making adjustments to scopes and sights to ensure accuracy when targeting at various distances.

When shooters refer to "adjusting for MOA," they are typically making precise calculations to account for bullet drop, windage, and other factors that influence the path of the projectile. Thus, understanding MOA is essential for achieving improved accuracy in shooting sports and military operations. An incorrect understanding of MOA could lead to significant errors in targeting, making this concept foundational for anyone engaged in shooting activities.
