The coefficient of reduction or form factor is calculated by the formula:
A.) 1/2gt2 (Where ‘g’ is the acceleration due to gravity and ‘t’ is the time taken)
B.) Avn (Where ‘A’ and ‘n’ are constants and ‘v’ is the velocity of the projectile)
C.) W/d2 (Where ‘W’ is the weight of the projectile and ‘d’ is the cross-sectional diameter)
D.) Ö[(4r-1)/7] (Where ‘r’ is the original radius (in calibres) of the projectile))
