.308 caliber round
The .308 caliber round is the third rarest Small Guns ammunition found in the game, next to .44 round, magnum, and 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. A notable sniper is Arkansas in Minefield. 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 a stockpile of ammunition is acquired.

- Lucky Harith will have many of these rounds after investing in him during the unmarked quest Merchant Empire.
