For an overview of 10mm ammunition types in the Fallout series of games, see 10mm.

10mm is a type of ammunition in Fallout and Fallout 2.


Main article: 10mm
Before the War, 10mm was the standard ammo for the Bureau of Alcohol, Drugs, Tobacco, Firearms and Lasers, while the military was more reliant on experimental energy weapons.


The 10mm is the most common ammo found in the wasteland. The JHP is intended to shoot low-armed people, while AP gives more power to cut through armors.


There are two variants of 10mm ammunition:

  • 10mm AP (Ammunition. Caliber: 10mm, armor piercing.)
  • 10mm JHP (Ammunition. Caliber: 10mm, jacketed hollow-points.)

Weapons using this ammunitionEdit



10mm AP:

10mm JHP:

  • Standard starting inventory includes 48 10mm JHP rounds.
    • Tagging Small Guns increases this by an additional 24 rounds.
  • Various merchants
  • Raiders during the quest Help Irwin carry the ammunition.

Fallout 2Edit

10mm AP:


In Fallout, ammunition modifiers are not applied properly which makes the 10mm equal to any other kind of ammunition and both JHP and FMJ versions functionally identical.
