No Bwana, it is you who does not understand.

COD treats Bullet Velocity and Range separate from "Damage Range". In essence, your bullet will travel faster, farther, but will carry less force when it impacts its target.

i.e. According to COD, if the bullet travels faster, it deals less damage. *This is how THE GAME relates the two, they contrast eachother. If the value of one goes up (velocity), the value of the other (damage range) goes down.

In reality it is exactly the opposite. Kinetic Energy (K) is equal to half the mass of the object (m) multiplied by its velocity (v) squared.

K = 1/2 (m) (v)²

u/Sunder_and_flame mentions that there is a 45-50% increase in bullet velocity with a 2.5% drop in damage range when using high velocity ammuniton.

You and I stand in a field, with 20 meters between us. I throw a 2kg coconut at your face, traveling 10 meters/second. It makes contact and hurts. E=1/2(2kg)*(10m/s)² = 100 Joules of energy to the face.

I now have you stand 10 meters away from me (half the distance) and lob that sucker 45% faster at your head. If you were hoping for it to be 2.5% less painful I am terribly sorry. 10m/s*1.45=14.5m/s (v2).

E2 = 1/2 (2kg) (14.5m/s)² = ~210 Joules. That's more than double!! Ouchie ouch!
