**Inspiring Barnes Ballistic Coefficient Chart
Pics**. 2000 fps sight height : The ballistic coefficient is the ability of a bullet to overcome or beat air resistance as it is flying through time and space, and this is basically the exact opposite of the negative acceleration.

It is inversely proportional to the negative acceleration: Almost all rounds have a ballistic coefficient of less than 1.0, but large rounds like the 50 bmg can exceed this normal bc. But note that ballistic coefficients are not, in themselves, a measure of accuracy.

Barnes calculates ballistics using doppler radar speed data. I thought it might be interesting show how you can approximate the drag coefficient for a bullet given a standard bullet in figure 4, i compare the barnes' g7 drag coefficient data with my calculated drag coefficient. Ballistic coefficient & bullet math : A ballistic coefficient is the measure of a bullet's relative ability to overcome air resistance.
