.50 Caliber

A bullet that is very long and powerful. It is used in some sniper rifles (like the Barret .50 Cal) , AA guns, and sometimes chainguns or mounted machine guns. The bullet is about the length of an average middle finger. It is used to take down vehicles and armored personnel. This munition is not commonly used against lightly armored personnel, but it can still take someone out with one hit.
