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 acceptable recoil. Early 12-gauge ...
The recurring cost depends heavily on which published recipe is used. Some published recipes for handloading 1 oz (437.5 gr (28.35 g) 12 gauge slugs require as much as 49 gr (3.2 g) of powder each, whereas other 12 gauge recipes for 7 ⁄ 8 oz (383 gr (24.8 g) slugs require only 25 gr (1.6 g) of powder.

The AA-12 (Auto Assault - 12), originally designed and known as the Atchisson Assault Shotgun, is a fully automatic combat shotgun developed in 1972 by Maxwell Atchisson. . However, the original development by Atchisson seems to have produced only a few guns at prototype-level, with the development that ultimately led to the gun entering the market being done later by Military Police Systems ...
At any reasonable range, shotgun slugs make effective lethal wounds due to their tremendous mass, reducing the length of time that an animal might suffer. For example, a typical 12-gauge shotgun slug is a blunt piece of metal that could be described as an 18 mm (.729 inch) caliber that weighs 28 grams (432 grains).
This means they are not compatible for use with low powered rounds, e.g. less-than-lethal ammunition. The most common shotgun shell used in combat shotguns contains 00 buckshot , 8 to 10 lead balls , which is very effective against unarmored targets.
For example, a shotgun is called "12-gauge" because a lead sphere that just fits the inside diameter of the barrel weighs 1 ⁄ 12 pound (38 g). This measurement comes from the time when early cannons were designated in a similar manner—a "12 pounder" would be a cannon that fired a 12-pound (5.4 kg) cannonball; inversely, an individual "12 ...
Effective range: The maximum range at which a particular firearm can accurately hit a target. Electronic firing: The use of an electric current to fire a cartridge, instead of a percussion cap. In an electronic-fired firearm an electric current is used instead to ignite the propellant, which fires the cartridge as soon as the trigger is pulled.
Dragon's breath is normally chambered in 12-gauge 2 + 3 ⁄ 4 ″ (18.5 mm × 69.9 mm) shot shells. The rounds are safe to fire out of an improved cylinder bore as well as a modified choke barrel, common on many shotguns.
