The shell body dropped to the ground mostly intact and the bullets continued in an expanding cone shape before striking the ground over an area approximately 250 yards × 30 yards in the case of the US 3-inch shell. [34] The effect was of a large shotgun blast just in front of and above the target, and was deadly against troops in the open.
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.
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.
With quick firing guns (those using metallic cartridge cases) the case itself is fitted with the igniting medium; in England these are called primers. For small guns the case contains a percussion primer, usually a copper cap filled with a chlorate mixture and resting against an anvil. [2] The striker of the gun strikes the cap and fires the ...
