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 .
The striker of the gun strikes the cap and fires the mixture. For larger guns an electric primer is used, the internal construction and action of which are precisely similar to the wireless tube already described; the exterior is screwed for the case. For percussion firing an ordinary percussion tube is placed in an adapter screwed into the case.
The Federal Bureau of Investigation briefly field-tested the 10mm Auto using a M1911 pistol and a Thompson Model 1928 submachine gun [19] [20] as an "urban carbine" before adopting the Smith & Wesson Model 1076 in 1990; a short-barreled version of the Model 1026 with its slide-mounted decock/firing pin block safety supplanted by only a frame ...
Ordnance crest "WHAT'S IN A NAME" - military education about SNL. This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
Some machine gun and autocannon cartridges (such as the MG 131 13mm and M61 Vulcan 20mm) utilize an internal electric primer that contains chemicals activated by an externally provided electric charge, as opposed to a mechanical impact. The primer in turn ignites the main propellant, just as with a shock-sensitive or external electric type.
The components are, from left to right: the solid propellant, the primer, the bullet, and a plastic cap that serves to keep the bullet centered in the propellant block. Modern caseless ammunition typically uses a configuration in which the primer and projectile gets integrated into a solid mass of external propellant (originally nitrocellulose ...

They use a large, specific shotgun primer that is based on the Boxer system, in that the primer contains the anvil against which the primary explosive is compressed by the firing pin and deformation of the primer cup. Shotgun primers are also used as a replacement to the percussion cap ignition system in some modern black-powder firearms, and ...
