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 ...
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 ...
Long recoil operation is found primarily in shotguns, particularly ones based on John Browning's Auto-5 action. In 1885 a locked breech, long recoil action was patented by the Britons Schlund and Arthur. [9] In a long recoil action, the barrel and bolt remain locked together during recoil, compressing the recoil springs.
The six most common shotgun gauges, in descending order of size, are the 10 gauge, 12 gauge, 16 gauge, 20 gauge, 28 gauge, and .410 bore. [7] By far the most popular is the 12 gauge, [7] particularly in the United States. [8] The 20-gauge shotgun is the next most popular size [citation needed], and is popular for upland game hunting. The next ...
The Winchester Model 1200 pump action shotgun employs a rotating bolt in a bolt carrier (slide) rather than the tilting breechblock used in the Model 12. [10] The Model 1200 was the second shotgun design to utilize a rotating bolt; the Armalite AR-17 being the first. [6] The bolt locks directly into the barrel and has four locking lugs.
The Model 11-87 incorporates a self-compensating gas system design, which allows the gun to operate with a range of loads, from light 2 + 3 ⁄ 4-inch (7.0 cm) shells to 3-inch (7.6 cm) Magnum shells, without any adjustment by the operator. It is manufactured in 12 gauge and 20 gauge; both will cycle 2 + 3 ⁄ 4-inch and 3-inch shells.
Designed by Wayne Leek and Robert Kelley, [2] [3] the Remington Model 1100 was introduced in 1963 as a successor to the Model 58 and Model 878 gas operated shotguns. [4] The Model 58 had supplanted the recoil operated Model 11-48, which retained the long recoil action of John Browning's original design, present in the Model 11 and the Browning Auto-5.
The change from one barrel to the other may be done by a clockwork type system, where a cam alternates between barrels, or by an inertial system where the recoil of firing the first barrel toggles the trigger to the next barrel. A double-barreled shotgun with an inertial trigger works best with full power shotshells; shooting low recoil ...
