Free recoil / Frecoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy ( E t ) imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb f ) for non-SI units of measure.
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 ...
7.5 pounds (3.4 kg) (26") ... Remington states that the Versa Max "reduces 12 gauge recoil to that of a 20 gauge." [6] The action of the Versa Max is a redesign of ...
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.
Gauge was 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 sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Therefore with a 12-gauge, it would take 12 balls of lead of the same size as the 12 gauge ...
The Browning Double Automatic Shotgun is a short-recoil operated [2] semi-automatic (auto-loading) 12-gauge shotgun with a 2 + 3 ⁄ 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.
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-gauge" shot would in fact be a 1 ⁄ 12 pounder. Thus, a 10-gauge shotgun has a larger-diameter barrel than a 12-gauge shotgun, which has a larger ...
The Model 11-87 is a gas operated semi-automatic shotgun.Upon firing a shell, some of the high-pressure gases from the burning propellant are diverted through two small holes under the barrel, [2] forcing the bolt toward the buttstock, which in turn ejects the spent shell.
