BBs are likely a useless ammo type to most. Heavy, rare, and 2/3rds of the guns that chamber them are useless compared to the starting guns. However, if Bob's Pre-owned Car Mart is encountered (Fallout), or Dobbs is revived in the Sierra Army Depot (Fallout 2), a Red Ryder LE BB gun may be found, which makes very effective use of cheap BBs.
