A supplemental chamber or cartridge adapter is typically used for a shorter cartridge of reduced diameter. [1] A cartridge conversion sleeve may include a short barrel of reduced bore diameter. Shotgun conversion sleeves may be called subgauge inserts , subgauge tubes , or gauge reducers .

A shotgun cartridge, shotshell, or shell is a type of rimmed, cylindrical (straight-walled) ammunition used specifically in shotguns.
The Coffman engine starter (also known as a "shotgun starter") was a starting system used on many piston engines in aircraft and armored vehicles of the 1930s and 1940s. It used a cordite cartridge to move a piston, which cranked the engine.
The sabot component in projectile design is the relatively thin, tough and deformable seal known as a driving band or obturation ring needed to trap propellant gases behind a projectile, and also keep the projectile centered in the barrel, when the outer shell of the projectile is only slightly smaller in diameter than the caliber of the barrel ...
Even in completely plastic-bodied cartridges, such as the Activ brand shotgun shells, a thin metal ring is molded into the rim to provide support for the extractor. [10] [15] [16] A secondary issue is that ammunition in use can be exposed to air, water, lubricants, and solvents. Primer and propellant in external-propellant caseless rounds is ...
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.
In the 1880s a gas piston-operated rifle and pistol were developed by the Clair Brothers of France who received a French patent and submitted prototypes for testing by the French army in 1888 although the true date of their invention is uncertain. They would also produce a semi-automatic shotgun in the early 1890s.
