The .38 round is a type of ammunition in Fallout 4.


Manufactured by Circle G, .38 rounds are small caliber ammunition. They were originally designed for double-action revolvers pre-War, but after the Great War, the ammunition's abundance made it a good choice for improvized weaponry. They were originally sold in boxes of 50 cartridges.
