I found this on another board

Using the Weapons muzzle velocity times the caliber and divide by 50 and you could come up with the E-Factor for any weapon.

"A projectile carries energy with it to the target and in this manner causes damage. This energy takes the form of the speed in which the projectile strikes the target. It was to account for this energy that the E-factor was developed."

"The term E-factor comes from the Efficiency of a projectile. It accounts for the amount of armor a projectile can penetrate as well as the damage it does. The E-factor is found by multiplying the projectile's diameter, in thousandths of an inch, times the muzzle velocity of the projectile, in feet per second, divided by 50."

(D x V) ÷ 50 = E
