Calculation of the sectional density is straight forward. For a 300 grain, .338 caliber bullet, the sectional density is: SD = [ 300 gr / (7000 gr/lb) ] / [ 0.338 in ] 2 = 0.375 lb/in 2. NOTE: With the common definition of the sectional density, the units have to be converted when used with drag functions, velocity, etc, to convert the in 2 to ...Terminal ballistics: the study of the interaction of a projectile with its target, whether that be flesh (for a hunting bullet), steel (for an anti-tank round), or even furnace slag (for an industrial slag disruptor)." ...

The ballistic coefficient is represents the ratio of the drag of the standard (e.g. G1 standard bullet) bullet to that of the bullet you are shooting. A ballistic coefficient of 0.100 means that your bullet has 10 times the drag of the standard bullet. Barrel Twist The twist length of the barrel. Twist Direction
