  2. Recoil - Wikipedia

    en.wikipedia.org/wiki/Recoil

    For a gun firing under free-recoil conditions, the force on the gun may not only force the gun backwards, but may also cause it to rotate about its center of mass or recoil mount. This is particularly true of older firearms, such as the classic Kentucky rifle , where the butt stock angles down significantly lower than the barrel, providing a ...

  3. 20-gauge shotgun - Wikipedia

    en.wikipedia.org/wiki/20-gauge_shotgun

    Loads for waterfowl will tend to produce more felt recoil in a 12-gauge shotgun than in a 20, but this may not be the case depending on the gun used. [9] Full-power 20-gauge shells fired from a light 5 lb (2.3 kg) gun will have more felt recoil than those fired from a heavy 7 lb (3.2 kg) gun. [ 11 ]

    According to Newtonian mechanics, if the gun and shooter are at rest initially, the force on the bullet will be equal to that on the gun-shooter. This is due to Newton's third law of motion (For every action, there is an equal and opposite reaction). Consider a system where the gun and shooter have a combined mass m g and the bullet has a mass m b.

  5. Double-barreled shotgun - Wikipedia

    en.wikipedia.org/wiki/Double-barreled_shotgun

    Side-by-side shotguns are often more expensive, and may take more practice to aim effectively than an over-and-under. The off-center nature of the recoil in a side-by-side gun may make shooting the body-side barrel slightly more painful by comparison to an over-and-under, single-shot, or pump-action, lever-action shotgun.

  6. KS-23 - Wikipedia

    en.wikipedia.org/wiki/KS-23

    The first shotgun was made in 1995. [5] It has been legal to use as a civilian hunting shotgun in Russia since August 1996. [6] The gun maker's website has this as the description for the shotgun. The shotgun is multicharged, with a tubular underbarrel magazine of 3-cartridge capacity. Reloading is provided with a removable fore-end.

  7. Comparison of the AK-47 and M16 - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_the_AK-47...

    This weapon was the prototype of all successful automatic rifles. Characteristically (and unlike previous rifles and the M-14) it had a straight stock with the barrel under the gas cylinder to reduce the turning moment of recoil of the rifle in the shoulder and thus help reduce the tendency of shots to climb in automatic fire.

  8. Muzzle velocity - Wikipedia

    en.wikipedia.org/wiki/Muzzle_velocity

    For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...

  9. Remington Model 58 - Wikipedia

    en.wikipedia.org/wiki/Remington_Model_58

    The Remington Model 58, also known as the Sportsman 58, is a semi-automatic shotgun manufactured by Remington Arms in the mid-20th century. It was Remington's first gas operated shotgun and was marketed alongside the recoil operated Model 11-48.
