Gatling gun

The Gatling gun's operation centered on a cyclic multi-barrel design which facilitated cooling and synchronized the firing-reloading sequence. As the handwheel is cranked, the barrels rotate and each barrel then loads a single round of cartridge from a top-mounted magazine, fires off the shot when it reaches the set position. The barrel is empty and allowed to cool until rotated back to the top position and gravity-fed another new round. Due to the advancing technology, this could be increased and upgraded for machine-gun level rates of fire, heavier rounds, or longer ranges.
