10mm (Fallout)

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

Characteristics
The 10mm is the most common ammo found in the wasteland. The JHP is intended to shoot low-armored targets, while AP gives more power to cut through armors, but has lower overall damage.

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.

Variants
There are two variants of 10mm ammunition:
 * 10mm AP (Ammunition. Caliber: 10mm, armor piercing.)
