5mm Round (Fallout: New Vegas)

The 5mm round is a type of ammunition in Fallout: New Vegas.

Characteristics
5mm is traditionally belt-fed, and is available in rather high quantities, something made necessary by the notably large "magazine" sizes on the weapons that use it. For example, the Minigun loads 240 rounds at one time and fires an exceptional rate, requiring that the player carries a huge supply if they intend to rely on miniguns.

5mm, Armor Piercing
Armor-piercing rounds are designed for punching through armor plating, for this purpose they have a greatly strengthened case with a specially hardened and shaped nose. Due to the high muzzle velocity and penetrative property's of the round damage to the target is slightly reduced. They are more common and can be purchased in larger numbers than any other type of AP rounds in game.

5mm, Hollow Point
Hollowpoint bullets mushroom out upon impact, tearing through fabric, flesh and organs creating a larger wound cavity. However, hollowpoints lack the penetrating power to punch through denser materials, this means they pierce things like armor plate, drastically reducing the weapon's penetrating power.

5mm, Surplus
Surplus ammunition is poor grade ammunition made in larger quantities by using corrosive materials in their construction. The resulting process is a slightly more damaging round but at the cost of more regular maintenance on a firearm due to the highly damaging corrosive materials used in the rounds construction.
