.44 Round, Magnum (Fallout 3)

The .44 round, magnum is a 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 the Scrounger perk, .44 Magnum ammunition still remains less common than 10mm or .32 caliber ammunition. However, significant caches can be found, drastically improving the usefulness of those powerful weapons.

 * Scoped .44 magnum
