The Definition of Automatic
A type of firearm which, utilizing some of the recoil or some of the expanding-gas energy from the firing cartridge,
cycles the action to eject the spent shell, to chamber a fresh one from a magazine, to cock the mainspring and to fire again.
Such a firearm will fire continuously as long as the trigger is held back, until the magazine is empty. A machine gun.
A firearm thus activated, but which shoots only one bullet with each separate pull of the trigger,
while often erroneously referred to as "automatic" is properly termed Semi-Automatic.

Is small arms ammunition that has been loaded to a higher internal pressure than standard for it's caliber.
