.44 Round, Magnum (Fallout 3)

The .44 Round, magnum is the rarest Small Guns ammunition found in Fallout 3 (other than BBs). 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.

Players who intend to make use of weapons chambered for .44 Magnum rounds would be well-behooved to take the Scrounger perk as soon as it is available. With this 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.
