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 improvised weaponry. They were originally sold in boxes of 50 cartridges.

Box art for .38 rounds implies that they are rimmed cartridges used in revolvers but weapons in game treat it as an automatic pistol cartridge. The model for a .38 cartridge appears to be rimless.
