A shotgun, also called a "scattergun," is a firearm designed to shoot a multitude of lead or steel balls of varying sizes. This makes it very effective at hunting game, greatly increasing the weapon's hit potential. However, the accuracy and power found at close range starts too diminish as the target gets farther away. Shotguns designed for the military's use are often called "combat shotguns."
