EasyBC is a straightforward application that calculates the Ballistic Coefficient of a projectile. Three methods are offered: only one chronograph (the '∆POI' method), one calibrated chronograph and a millisecond timer (the '∆T' method) or two matched and calibrated chronographs (the '∆V' method). An Environmental applet is supplied together with a Table and graphs of the trajectory and a brief help file.
