but in gerneral
There are 4 catagories of ammo in any particular chambering.
FMJ - full metal jacket - standard military. Offers good penetration and knock down power
JHP - jacket hollow point - typically used by Law enforcement - bullet collapses on itself on impact which has very good lethality on unarmored tagets, but very poor on armored.
AP - Ammor Piercing - speciality - Designed with a hard bullet it's high density helps it "cut" through armor, but doesn't offer very good stoping power on unarmored personal.
tracer - the bullet burns a chemical that causes it glow through the air. The effect looks somewhat like a "star wars" laser blast and is designed to help you aim by being able to see how the bullet traves. On the down side it also gives your position away.
--- ammo is also genneraly put into 1 of two catagories.
sub-sonic: bullets travel slower than the speed of sound. They dont have very long range, but are optimial for use with supressors (aka silencers) because the bullets dont make a loud noise as they travel through the air.
Super sonic: Most rifle rounds fall into this catagory. The bullets travel faster than the speed of sound so they crack the sound barrier when fired. Because the move so fast they're good for hitting targets that are farther away.
In infiltration you have these types of ammo
9mm Luger (parabellum) - M9/Berreta - Very common in pistols, and sub machine guns. Nothing very special here. Invented for the german Luger of ww2, it turned out to be very effective cause it didn't offer alot of recoil and its good at short range.
.40 simth & wesson - Mp5/40 - More bang than a 9mm but less than a .45acp.
.357 magnum. - Desert Eagle - Once was coined as the most powerfull handgun round in the world, it still offers alot of power today.
5.7 X 22mm - Five seven - P90 - Unique cartridge invented in the earlly 90's. It's actually thiner than a 9mm, but is longer. It's supposed to be very good at armor piercing, but it's not very damaging. I like to think of it as a AP .22

.223 rem (5.56 X 45mm Nato) - First designed for the M16. The round is a light high velocity type. today its considered the standard round used in all assault rifles (at least nato nations)
.308 winchester (7.62X51mm Nato) - Older than the .223 this was the first Nato round. Baiscally designed to replace the .30-06 from the early 1900's. Today because it's large heavy bullet in an with alot of bang, it's only used sniper rilfes since it's not as easily effect by things like wind which would effect the .223 It's also got more power. For a while it was used alot in assualt rifles ( though some would call them battle rifles ) but it was generally considered over kill since the recoil was too harsh for an automatic, it's longer range wasn't being taken advantage of by iron sights.. ect
7.62 X 39 russian - Russians used this round for their AK47's. It's just a little less powerfull than a .30-30 but more powerfull than a 357 Mag.
.50BMG Originally designed as an anti-tank round for the Browning m2HB WW1. It's still used today as an anti material, and anti personal weapon. It's half and inch wide, and about 5 inches long. it's used in some sniper rifles, but mostly in heavy machine guns like those found on tanks.
i think that's all of them..
