.44 Round, Magnum (Fallout 3)

The .44 Round, magnum is the second rarest Small Guns ammunition found in Fallout 3.

Characteristics
Very few enemies carry weapons that use this ammunition, and as such it is virtually never found on bodies and must be either purchased or looted from stockpiles, where it is still uncommon. With Scrounger perk, although .44 Magnum ammunition remains less common than 10mm or .32 caliber ammunition, significant caches can be found, drastically improving the usefulness of those powerful weapons.

Weapons using this ammunition

 * Scoped .44 magnum
