22LR
The .22 Long Rifle or simply .22 LR or 22 (metric designation: 5.6×15mmR) is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of rifles, pistols, revolvers, smoothbore shotguns, and submachine guns. In terms of units sold it is by far the most common ammunition in the world today. Common uses include hunting and shooting sports. Ammunition produced in .22 Long Rifle is effective at short ranges, has little recoil, and is cheap to purchase, making it ideal for training. History American firearms manufacturer J. Stevens Arms & Tool Company introduced the .22 Long Rifle cartridge in 1887. The round owes its origin to the .22 BB Cap of 1845 and the .22 Short of 1857. It combined the case of the .22 Long of 1871 with a bullet, giving it a longer overall length, a higher muzzle velocity and superior performance as a hunting and target round, rendering the .22 Extra Long cartridges obsolete.

Older 19th century cadet rifles were simply smaller and lighter versions of standard issue service rifles designed to fire reduced power cartridges.

22 Long
22 Long is a variety of 22 caliber (5.6 mm) rimfire ammunition. The 22 Long is the second-oldest of the surviving rimfire cartridges, dating back to 1871, when it was loaded with a 29 grain (1.9 g) bullet and 5 grains (0.32 g) of black powder, 25% more than the 22 Short on which it was based. It was designed for use in revolvers, but was soon chambered in rifles as well, in which it gained a strong reputation as a small game cartridge, and sold very well. In 1887 the 22 Long case was combined with the heavier 40 grain (2.6 g) bullet of the 22 Extra Long of 1880 to produce the 22 Long Rifle giving a longer overall length, a higher muzzle energy and superior performance as a hunting and target round, rendering the 22 Long and 22 Extra Long obsolete. Many firearms designed for the 22 Long Rifle will chamber and fire the shorter round, though the 22 Long generally does not generate sufficient energy to operate semi-automatic guns. The one prominent survivor of the 22 Long i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolver
A revolver (also called a wheel gun) is a repeating firearm, repeating handgun that has at least one gun barrel, barrel and uses a revolving cylinder (firearms), cylinder containing multiple chamber (firearms), chambers (each holding a single cartridge (firearms), cartridge) for firing. Because most revolver models hold up to six rounds of cartridge before needing to reload, revolvers are also commonly called six shooters. Before firing, cocking the revolver's hammer (firearms), hammer partially rotates the cylinder, indexing (motion), indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. The hammer cocking in nearly all revolvers are manually driven, and can be achieved either by the user using the thumb to directly pull back the hammer (as in trigger (firearms)#Single-action, single-action), via internal linkage (mechanical), linkage relaying the force of the trigger-pull (as in trigger (firearms)#Double-actio ...

22 Short
.22 Short is a variety of .22 caliber (5.6 mm) rimfire ammunition. Developed in 1857 for the first Smith & Wesson revolver, the .22 rimfire was the first American metallic cartridge. The original loading was a bullet and of black powder. The original .22 rimfire cartridge was renamed .22 Short with the introduction of the .22 Long in 1871. Developed for self defense, the modern .22 Short, though still used in a few pocket pistols and mini-revolvers, is mainly used as a quiet round for practice by the recreational shooter. The .22 Short was popularly used in shooting galleries at fairs and arcades; several rifle makers produced " gallery" models for .22 Short exclusively. Due to its low recoil and good inherent accuracy, the .22 Short was used for the Olympic 25 meter rapid fire pistol event until 2004, and they were allowed in the shooting part of modern pentathlon competitions before they switched to air pistols. Several makes of starter pistols use .22 Short blan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. In hand-held small arms, the recoil momentum will be eventually transferred to the ground, but will do so through the body of the shooter hence resulting in a noticeable impulse commonly referred to as a "kick". In heavier mounted guns, such as heavy machine guns or artillery pieces, recoil momentum is transferred to the Earth's surface through the platform on which the weapon is mounted. In order to bring the rearward moving gun to a halt, the momentum acquired by the gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
External Ballistics
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field. Gun-launched projectiles may be unpowered, deriving all their velocity from the propellant's ignition until the projectile exits the gun barrel. However, exterior ballistics analysis also deals with the trajectories of rocket-assisted gun-launched projectiles and gun-launched rockets; and rockets that acquire all their trajectory velocity from the interior ballistics of their on-board propulsion system, either a rocket motor or air-breathing engine, both during their boost phase and after motor burnout. External ballistics is also concerned with the free-flight of other projectiles, such as balls, arrows etc. Forces acting on the project ...

Plinking
Plinking refers to informal target shooting done for pleasure, typically at non-standard targets such as tin cans, logs, bottles, or any other homemade or naturally occurring target. Practice In contrast to shooting done at established target ranges, plinking is generally done at home, in an open field, or other private land for no fee. The term ''plinking'' is an onomatopoeia of the sharp, metallic sound (or "plink") that a projectile makes when hitting a metal target such as a tin can. The most common caliber used for plinking is the .22 Long Rifle rimfire cartridge, since these rounds are relatively inexpensive and have a low recoil; however, any caliber can be used in plinking, and it is not unusual to see a person plinking with a full power rifle or pistol. Air guns and airsoft guns are also used, often for cost or safety reasons or because they are subject to less stringent regulation - a similar practice with a bow and arrow is usually termed "stump shooting".

M1911
The M1911 (Colt 1911 or Colt Government) is a single-action, recoil-operated, semi-automatic pistol chambered for the .45 ACP cartridge. The pistol's formal U.S. military designation as of 1940 was ''Automatic Pistol, Caliber .45, M1911'' for the original model adopted in March 1911, and ''Automatic Pistol, Caliber .45, M1911A1'' for the improved M1911A1 model which entered service in 1926. The designation changed to ''Pistol, Caliber .45, Automatic, M1911A1'' in the Vietnam War era. Designed by John Browning, the M1911 is the best-known of his designs to use the short recoil principle in its basic design. The pistol was widely copied, and this operating system rose to become the preeminent type of the 20th century and of nearly all modern centerfire pistols. It is popular with civilian shooters in competitive events such as the International Defensive Pistol Association and International Practical Shooting Confederation. The U.S. military procured around 2.7 million M1911 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
