Physics

External Ballistics:
Bullet Drop (approx):

193 * (time of flight) ^2

Kinetic Energy (Ballistic):

((Bullet Weight (Grains) / 225218 * Velocity) ^2) /2

Energy Transfer (Ballistic): 

Kinetic Energy * Calibre

Wind Drift (Inches):

12 * (88*5 / 60) * sin(a) * (t - (3 * r) / v)

t= Time of Flight (seconds)

s= Wind Speed (MPH)

a= Angle of Wind off Bullet Trajectory

c= Muzzle Velocity (fps)

r= Range to Target (Yards)
