A minute of angle (MOA), a unit of angular measurement equal to 1/60th of a degree, is frequently used to describe the accuracy potential of firearms and ammunition. Thirty MOA represents a cone of dispersion roughly one inch in diameter at 100 yards. This measurement is often employed as a benchmark for evaluating the precision of rifles, ammunition, and sighting systems, particularly in long-range shooting disciplines. Achieving such tight groupings at extended distances requires a combination of high-quality components, precise manufacturing tolerances, and skilled marksmanship.
The pursuit of minimal dispersion is paramount in various shooting applications, including competitive target shooting, hunting, and military or law enforcement operations. Smaller groupings translate to increased accuracy and higher hit probabilities, especially at longer ranges. Historically, this level of precision was primarily the domain of specialized, custom-built firearms. However, advancements in manufacturing techniques and materials science have made this standard attainable in more commonly available firearms. This progression has significantly influenced the development of shooting techniques and equipment, leading to improved performance across diverse shooting disciplines.
