The gauge (in American English or more commonly referred to as bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) of the barrel. Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the ...
Shotgun cartridge. A 12-gauge shotgun cartridge in a transparent plastic hull, allowing the contents to be seen. From left to right: brass, propellant, over-powder wad, shot wad, #8 birdshot, over-shot wad, and crimp. A shotgun cartridge, shotshell, or shell is a type of rimmed, cylindrical (straight-walled) ammunition used specifically in ...
Military 12-gauge cartridges. Military use of combat shotguns through the 20th century has created a need for ammunition maximizing the combat effectiveness of such weapons within the limitations of international law. 12- gauge has been widely accepted as an appropriate bore diameter to provide an effective number of projectiles within an ...
Shotgun. A shotgun (also known as a scattergun, peppergun, [1] or historically as a fowling piece) is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which discharges numerous small spherical projectiles called shot, or a single solid projectile called a slug.
For example, the barrel of a 12-gauge shotgun is equal to the diameter of a 1/12 of a pound lead ball (0.729 in) and a 20-gauge can fit a 1/20 pound lead ball (0.615 in). Using this method, a .410 bore is equivalent to a (hypothetical) 67-gauge, instead of the incorrectly labeled 36 gauge (0.506) in Europe and South America. [15] [16]
The diameter of the wad slug is slightly less than the nominal bore diameter, being around 0.690 in (17.5 mm) for a 12-gauge wad slug, and a wad slug is generally cast solely from pure lead, necessary for increasing safety if the slug is ever fired through a choked shotgun. Common 12 gauge slug masses are 7 ⁄ 8 oz ((383 gr (24.8 g)), 1 oz ...
Shotguns are classed according to gauge, a related expression. The gauge of a shotgun refers to how many lead spheres, each with a diameter equal to that of the bore, that amounts to one pound (454 g (1.0 lb)) in weight. In the case of a 12-gauge (18.5 mm) shotgun, it would take 12 spheres the size of the shotgun's bore to equal a pound. [12]
The Browning Double Automatic Shotgun is a short-recoil operated [2] semi-automatic (auto-loading) 12-gauge shotgun with a 2⁄4 -inch chamber. The firearm was produced between 1952 and 1971, with production volume of approximately 67,000. Production date amended from 1955 to 1952 according to direct information from manufacturer.
