What does one box represent on a zero target?

One box on a zero target represents 1 Minute of Angle (MOA). MOA is a unit of angular measurement used in marking and shooting, and it is crucial for understanding how to accurately hit targets at varying distances. Specifically, 1 MOA at 100 yards approximately equates to 1 inch. Therefore, when a shooter refers to the measurement based on MOA, they are considering how their shot placement relates to this angular measurement, allowing for precise targeting adjustments.

Understanding that 1 MOA corresponds to 1 inch at 100 yards helps shooters make necessary corrections based on the distance to the target. For example, if a bullet hits 2 inches high at 100 yards, the shooter can adjust their aim down by 2 MOA to account for that deviation. This precise system aids in ensuring accuracy during marksmanship, especially in military or professional shooting contexts.
