22 Lr
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. The .22 LR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world.

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 gun is di ... [...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 projectile W ...

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 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AR-15
An AR-15-style rifle is any lightweight semi-automatic rifle based on the Colt AR-15 design. The original ArmaLite AR-15 is a scaled-down derivative of Eugene Stoner's ArmaLite AR-10 design. The then Fairchild Engine and Airplane Corporation division ArmaLite sold the patent and trademarks to Colt's Manufacturing Company in 1959. After most of Colt's patents for the Colt AR-15 expired in 1977, many firearm manufacturers began to produce copies of the Colt AR-15 under various names. While the patents are expired, Colt retained the trademark of the AR-15 and is the sole manufacturer able to label their firearms as ''AR-15''. The "AR" in Colt AR-15 stands for "ArmaLite Rifle", not " assault rifle". The Federal Assault Weapons Ban restricted the sale of the Colt AR-15 and some derivatives in the United States from 1994 to 2004, although it did not affect rifles with fewer listed features. After the term modern sporting rifles was coined in 2009 by the US National Shooting Sports F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merit Badge (Boy Scouts Of America)
Merit badges are awards earned by members of the Boy Scouts of America, based on activities within the area of study by completing a list of periodically updated requirements. The purpose of the merit badge program is to allow Scouts to examine subjects to determine if they would like to further pursue them as a career or vocation. Originally, the program also introduced Scouts to the life skills of contacting an adult they had not met before, arranging a meeting and then demonstrating their skills, similar to a job or college interview. Increasingly, though, merit badges are earned in a class setting at troop meetings and summer camps. Each merit badge has a pamphlet or booklet associated with it, which contains information on completing the requirements for the badge. Before starting to work on a particular badge, Scouts must meet with their Scoutmasters and obtain a signed application card for it. They must then contact an adult who is registered as a counselor for that badge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boy Scouts Of America
The Boy Scouts of America (BSA, colloquially the Boy Scouts) is one of the largest scouting organizations and one of the largest youth organizations in the United States, with about 1.2 million youth participants. The BSA was founded in 1910, and since then, about 110 million Americans have participated in BSA programs. BSA is part of the international Scout Movement and became a founding member organization of the World Organization of the Scout Movement in 1922. The stated mission of the Boy Scouts of America is to "prepare young people to make ethical and moral choices over their lifetimes by instilling in them the values of the Scout Oath and Law." Youth are trained in responsible citizenship, character development, and self-reliance through participation in a wide range of outdoor activities, educational programs, and, at older age levels, career-oriented programs in partnership with community organizations. For younger members, the Scout method is part of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
