Muzzle Velocity Measurement
Muzzle velocity, the speed at which a projectile leaves the barrel, is a standardized measure of airgun power. Chronographs, specialized devices designed for precise velocity measurement, are employed to capture this crucial data. Variations in muzzle velocity can result from factors such as barrel length, projectile weight, and air pressure. Accurate muzzle velocity data is essential for reliable energy calculations.
