The drag of a standard bullet typically ranges from 0.2 to 0.3 lbs at supersonic speeds, influenced by factors such as bullet shape, weight, muzzle velocity, and atmospheric conditions. While an ideal drag coefficient (Cd) is often cited between 0.2 and 0.4, Cd=0.3 is considered typical for standard trajectories. Weather conditions, including air density, temperature, and humidity, significantly impact drag and bullet performance. A higher drag can enhance stability and accuracy over longer distances, but excessive drag may reduce range. Understanding these dynamics is crucial for optimizing bullet performance in varying conditions.
