JBM - Calculations - Ballistic Coefficient (Velocity)

This calculator finds the ballistic coefficient of a bullet fired over a known distance. Main input variables are the distance, the muzzle velocity, velocity at distance, drag function, and atmospheric conditions. Explanation of terms.


Near Velocity (500-4500 ft/sec) [3000.0]
Far Velocity (500-4500 ft/sec) [2850.0]
Distance (1-6000 feet) [300.0]
Drag Function [G1]

Temperature (-40-140 °F) [59]
Pressure (15-40 inches Hg) [29.92]
Relative Humidity (0-100%) [0]
Altitude (-1000-15000 feet) [0]
Standard Atmosphere at Altitude Corrected Pressure
