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

Background[edit | edit source]

The following section is transcluded from 5mm round. To modify, please edit the source page.

A high velocity round designed for assault rifles, the intermediate 5mm M134 cartridge[1] has been replaced by the more powerful 5.56mm round in assault rifles.[2] However, it found a new life as linked, belt fed ammunition for man-portable miniguns on the battlefield, specifically the M134 cartridge and 7.62x51 millimeter rounds.[3] It has also been retained as the ammunition of choice for paratrooper assault carbines, due to its light weight and portability.[4]

Characteristics[edit | edit source]

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.

Full metal jacket (FMJ)[edit | edit source]

5mmap.gif

A softer metal jacket covers a dense penetrator, while the bullet is loaded with a higher powder load, leading to improved muzzle velocity. However, improved performance against armored targets leads to impaired performance against softer targets, as the higher velocity reduces the amount of kinetic energy transferred to the target on impact.

In game terms, it is strictly inferior to the JHP variant, as the damage redyctuib is not compensated for by the reduction in DR, not to mention that the DT of the target will even further reduce damage received compared to JHP.

Jacketed hollow point (JHP)[edit | edit source]

5mmjhp.gif

Hollow point bullets feature a hollowed out shape at the tip of the bullet, causing the bullet to expand upon impact, delivering more kinetic energy to the target and disrupting tissue more extensively. However, this same property also leads to reduced penetrative power, as the bullet will be stopped by armor much more easily due to its properties. A hard metal jacket is applied to JHP rounds to increase bullet strength and create a middle ground between damage potential and penetration.

Although the DR bonus applied by these rounds is noticeable, it is still not enough to make them perform worse than the AP ammo (which should be sold as soon as it is acquired).
