BBs, mainly. If you can breech load it, they can also fire pellets and darts.
To cock a gun means to load it sort of. Like, when you hear guns go like -chk chk-. When you cock a gun, you are placing the hammer in a position to fire the weapon.
A Gatling Gun works by using a series of rotating barrels to rapidly fire bullets. A motor is used to load and spin the barrels which allows for a high rate of fire with reduced heat buildup.
The Crosman 120 is a rifle not a gun. It is a break barrel. Cock the barrel all the way down and load a pellet into the rear of the barrel. Pull the barrel back up and it' is ready to fire.
