Fallout 3 Weapons Using .308 Caliber Round Ammunition

 * Sniper Rifle
 * Reservist's Rifle
 * Victory Rifle

Description
The .308 Caliber Round, essentially the civilian version of the well-known 7.62x51mm NATO round, is the third rarest small guns ammunition found in the game, next to .44 Round, Magnum, and the BBs; very few enemies carry Sniper Rifles, and many are located in hard to reach places or have only a small number of rounds to be looted. The Hunting Rifle largely provides the same effect while using the much more common .32 Caliber Round, making the Sniper Rifle and variants limited in effectiveness until the player gathers a stockpile of ammunition.

A large stockpile of .308 rounds can be found in the Bethesda Ruins. There is a sniper perched in a window of a dilapidated office building. While the Sniper Rifle itself is in poor condition, there are at least 50 .308 caliber rounds (with the "Scrounger" perk) to be looted from ammunition boxes by the window and from the dead Raider's corpse. Another set of .308 boxes can be found in Minefield near Arkansas. There is also a Sniper Rifle in an Hollowed-Out Rock south east behind Megaton with 10 .308 Caliber Round some stimpaks and a note.

Vendors
Chief Gustavo at Tenpenny Tower will often have a dozen or more rounds for sale, and restocks frequently. Flak and Shrapnel often have 8-10 rounds for sale, but not always. Knight Captain Durga in the Citadel will have 20 or more rounds frequently, but is not available until halfway through the main quest line. Karl may also have a few for sale. Occasionally Moira Brown at Craterside Supply in Megaton will sell this ammo.

Note that, with the new DLC The Pitt, an ammo press eventually becomes available. This press allows for easy and rapid conversion of one caliber of ammunition to another. Take full advantage of this; convert more common ammo types like .32 or 5.56mm to .308.
