This item guide will cover the following ammo types in Fallout New Vegas; 12ga and 5mm ammunition. Ammunition is used for the vast majority of ranged weapons in Fallout New Vegas, with each ammo type working for a specific set of guns. Ammo like the 12ga and 5mm is one of the most valuable resources in Fallout New Vegas and should be treated as such. The Scrounger perk can help offset the general scarcity of ammunition, although certain types will always be hard to find. In addition, ammo like the 12ga and 5mm ammunition can be crafted with various workstations scattered throughout the wastes. This new ability to craft ammo is one that should be utilized often, especially for those that like to fight Rambo style, dumping tons of lead into their opponents.
