5mm round (Fallout)

5mm round is a type of ammunition in Fallout and Fallout 2.

Gameplay
A decent round, though it is outclassed by 12 gauge shells and .223 FMJ rounds, since weapons chambered for these ammunition types come into play at around the same time. Still, it is cheap enough to be useful in certain situations where one needs a burst weapon.

Variants
Narrow, long cartridges of bottleneck-cased rifle ammunition, which are found in large ammo storage cans. Weapons that use this type of ammunition are typically automatic firearms which fire large amounts of ammo. There are two variants of 5mm ammunition:
 * 5mm AP (A brick of small caliber ammunition. 5mm armor piercing.)
 * 5mm JHP (A brick of small, lightweight ammunition. Caliber: 5mm, jacketed hollow-point.)

Fallout

 * Assault rifle
 * Assault rifle (exp. mag.)
 * Minigun
 * Avenger minigun
 * XL70E3

Fallout 2

 * Assault rifle
 * Assault rifle (exp. mag.)
 * Minigun
 * Avenger minigun
 * XL70E3

Fallout

 * Both versions can be found in the West Tek research facility.
 * Jake sells both versions.
 * Hub police in combat armor, stationed at the Hub entrance in Old Town carry 150 rounds of both versions of these, along with assault rifles.
 * Zack sells both versions, along with assault rifles.

Fallout 2

 * Buster occasionally sells both types of this ammo at Buster's Fine Emporium of Armament in the NCR Bazaar.
 * Some normal rounds can be awarded for helping establish a truce between the Slags and the farmers of Modoc.
 * Some New Khans in Vault 15 carry AP rounds along with assault rifles.
 * Marcus carries JHP and can be bartered with before acquiring him as a companion.

Bugs
In Fallout, ammunition modifiers are not applied properly which makes the 5mm equal to any other kind of ammunition, and both JHP and AP versions functionally identical.
