For an overview of .223 ammunition types in various Fallout games, see .223 round.

.223 FMJ is the only type of .223 caliber ammunition in Fallout and Fallout 2.


With a full metal jacket and a huge bonus to Damage Resistance and Armor Class reduction, the .223 FMJ is an ideal round that has a gun fit for almost every occasion. This makes most weapons associated with it very ideal to use.
