14mm

 is the only type of 14mm ammunition in Fallout, Fallout 2, and Van Buren. It's a fairly powerful ammunition but somewhat rare.

The only weapon to use this ammunition is the 14mm pistol.

With only half of the 14mm pistol's generous base damage applied due to the armor piercing nature of the round, this ammo causes the 14mm pistol to compare unfavourably with other similar weapons, like the .223 pistol and even the Desert Eagle .44.
