5mm round (Fallout 3)

The 5mm round is a Big Guns-only ammunition in Fallout 3.

Characteristics
The one and only ammunition type for the minigun, the 5mm round is designed for use in bulk. With 240 rounds per reload, the player is encouraged to use it in bulk against their targets.

The Gatling laser largely retires the 5mm as basic ammunition for Big Guns builds, though it may be useful in a backup capacity.

More notably, since ammunition is weightless, 5mm rounds can be used to create makeshift ladders through stacking their large containers.
