Highest and lowest ballistic coefficient
WebBallistic Coefficient is essentially a measure of air drag. The higher the number the less drag, and the more efficiently the bullet cuts through the air. So for purposes of flying through the air efficiently, the bigger the BC number the better. BC is what determines trajectory and wind drift, other factors (velocity among them) being equal. WebBallistic Coefficient values at Mach 1.75 (1954 fps @ ICAO Standard Atmosphere), should be used when calculating trajectories for shooting beyond 600 yds. Ballistic Coefficient …

Web5 de abr. de 2024 · Ballistic coefficient is typically measured with a 3 digit expression. Almost all rounds have a ballistic coefficient of less than 1.0, but large rounds like the … In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass. BC can be expressed with … Ver mais General $${\displaystyle C_{\text{b,Physics}}={\frac {m}{C_{\text{d}}A}}={\frac {\rho \ell }{C_{\text{d}}}}}$$ where: • Cb,Physics, … Ver mais Most ballistic mathematical models and hence tables or software take for granted that one specific drag function correctly describes the drag and hence the flight characteristics of a bullet related to its ballistic coefficient. Those models do not differentiate between Ver mais • External ballistics - The behavior of a projectile in flight. • Trajectory of a projectile Ver mais Background In 1537, Niccolò Tartaglia performed test firing to determine the maximum angle and range for a shot.

Web21 de jul. de 2024 · Because lift and drag are both aerodynamic forces, the ratio of lift to drag is an indication of the aerodynamic efficiency of the airplane. Aerodynamicists call the lift to drag ratio the L/D ratio, pronounced “L over D ratio.”. An airplane has a high L/D ratio if it produces a large amount of lift or a small amount of drag.
