12.7mm Round

 is a rare type of Ammunition in Fallout: New Vegas.

Characteristics
The Hauer Premium 12.7mm civic defense round is a consumer-grade pistol round of identical diameter to the military-grade .50 caliber, but less powerful.

12.7mm Round, Hollow Point
Hollow point bullets mushroom and break up on impact, causing massive trauma on fleshy, unarmored targets. However, this also means they break up when they hit things like armor plate, drastically reducing the weapon's penetrating power.
