Ammo Sharing

Some weapon in COD4 fire the same rounds. So weapons that fire the same round, can share ammo. This is kind of unrealistic in the real world cause you'd need to remove the rounds from the magazine and what not.. but who the f cares, its just a game. Ammo sharing is quite convenient too... carry two weapons with the same ammo = more ammo for the weapon you use more... walk over any gun that use the same ammo... you pick up ammo. Ok, i think you get the idea... so here are the guns that share ammo.

9mm x 19 Parabellum: M9 (or Berretta 92FS, the handgun) , MP5, Mini-Uzi

5.56mm x 45 NATO: M16A4, M4, G36C

7.62mm x 51 NATO: G3, M14, M21, M40A3, R700

And I'm not going to tell you what rounds the other weapons fire... I do know what rounds they are of course, because i'm a gun fanatic, but i won't, cause that'll just be showing off :P
