A projectile’s ability to overcome air resistance is quantified by a numerical representation of its aerodynamic efficiency. This measure, crucial for long-range shooting, is determined by factors like the projectile’s shape, mass, and diameter. For instance, a higher value indicates greater aerodynamic efficiency and, consequently, less drop and wind drift over distance.
Understanding this aerodynamic measure allows for more precise trajectory predictions and adjustments in various shooting disciplines, particularly long-range target shooting and hunting. Historically, advancements in projectile design, driven by the need for improved accuracy and extended range, have led to significant improvements in this area. This pursuit of superior ballistic performance remains a driving force in the ammunition industry.
