Rounds of ammunition are fed automatically; after firing, the empty shell casing is ejected through an evacuation door on the front of the turret. Cooling is provided by water circulating in layers of steel around the tube of the gun, and by an injection of air and water after every shot. The turret can be used in three modes:
Cartridge: The assembly consisting of a bullet, gunpowder, shell casing, and primer. When counting, it is referred to as a "round". Caseless ammunition: A type of small arms ammunition that eliminates the cartridge case that typically holds the primer, propellant, and projectile together as a unit. Casket magazine: A quad stack box magazine.
Segment shells, also known as ring shells: this anti-personnel explosive shell originated in British service in 1859 and was designed by William Armstrong for use with his new breechloading field guns. The projectile was made up of layers of iron rings within a thin cast-iron shell wall, held together with lead between them, with a hollow space ...

A round is a single cartridge containing a projectile, propellant, primer and casing. A shell is a form of ammunition that is fired by a large caliber cannon or artillery piece.

An extractor also performs the function of an ejector in revolvers. When the striking force applied to the ejector rod is hard and fast enough, the extractor will typically eject the empty case(s) from the cylinder. Some break-action shotguns are also designed to eject empty shells completely out of the chamber when the barrel is opened.
Rim lock is where the rim of the shell casing gets caught on the extractor groove of the casing underneath it. It is a common issue for calibers with large rims, such as 7.62×54mmR, or guns that have been rechambered for cartridges shorter than intended without replacing the original magazine with one that compensates for the shorter round.
