Consistant with Demisis' idea, I think each kind of ammo should have its behind-the-scenes pro / con, to add some sort of purpose to the different types other than price.

Ex.
Handgun Ammo ((All weapons using this ammo are dualable (Semi-Auto)
Uzi Ammo (All weapons using this ammo are automatic (20 Damage or Less)
AK Ammo (All weapons using this ammo are 20 Damage or More. (High-Freeze)

And have mini ezceptions like DR. Which complies with some but not all guidelines.
