A tabular representation depicts the expected vertical deviation of a projectile due to gravity over specific distances. This data is typically calculated for a particular cartridge loaded with a projectile of a specific weight, in this case, a .30-06 Springfield cartridge with a 180-grain bullet. Such tables often include additional information like velocity and energy at various ranges, and may incorporate variables like atmospheric conditions and sight height.
Understanding projectile trajectory is essential for accurate long-range shooting. These tables provide critical data for hunters and target shooters to compensate for bullet drop, enabling ethical harvests and precise shot placement. Historically, ballistic calculations were complex and time-consuming. Compiled data in a readily accessible format significantly simplified the process, allowing shooters to more effectively determine the required aiming adjustments at different ranges.
