What Is Sub Moa - Basically the shot group is a size of a penny. Web in the perfect world sub moa accuracy means means that the average distance between consecutive shots at a specific distance is less than 1 minute of angle, or roughly less than 1 inch at 100 yards. One moa is an angular measurement equal to 1/60th of a degree used for determining bullet impact on a target. In ballistic terms, a moa (minute of angle) is the arc formed by an angle of one minute or 1/60th of 1/360th of a circle (each degree is split into 60 minutes), like degrees on a compass.
