.22-250
The .22-250 Remington is a very high-velocity, short action, .22 caliber rifle cartridge primarily used for varmint hunting and small game hunting. It is capable of reaching over 4000 feet per second. It does find occasional use by women and young children for deer hunting because of its low recoil. Some jurisdictions prohibit the use of cartridges smaller than 6mm (e.g., .243 Winchester) for deer hunting. This cartridge is also sometimes known as the ''.22 Varminter'' or the ''.22 Wotkyns Original Swift''.Cartridges of the World 8th Edition, Book by Frank C. Barnes, DBI Books, 1997, Along with the .220 Swift, the .22-250 was one of the high-velocity .22 caliber cartridges that developed a reputation for remote wounding effects known as hydrostatic shock in the late 1930s and early 1940s. History The .22-250 started life as a wildcat cartridge developed from the .250-3000 Savage case necked down to take a .224 caliber bullet. In the early days of the cartridge there were ...

Wildcat Cartridge
A wildcat cartridge, often shortened to wildcat, is a custom cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created in order to optimize a certain performance characteristic (such as the power, size, or efficiency) of an existing commercial cartridge. Developing and using wildcat cartridges does not generally serve a purpose in military or law enforcement; it is more a hobby for serious shooting, hunting, gunsmithing, and handloading enthusiasts, particularly in the United States. There are potentially endless varieties of wildcat cartridge: one source of gunsmithing equipment has a library of over 6,000 different wildcat cartridges for which they produce equipment such as chamber reamers. Development of a wildcat Often, wildcats are commercially sold rounds that have been modified in some way to alter the cartridge's performance. Barrels for the caliber are originally manufactured by gunsmiths specializing in barrel making. Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
204 Ruger
The .204 Ruger is a centerfire rifle cartridge developed by Hornady and Ruger. At the time of its introduction in 2004, the .204 Ruger was the second-highest velocity commercially produced ammunition and the only centerfire cartridge produced commercially for bullets of .204 inch/ 5 mm caliber. Characteristics The .204 Ruger was developed from the .222 Remington Magnum, which has the second-largest case capacity in the family that began with the .222 Remington. Only the European 5.6×50mm Magnum is larger, which itself is a lengthened version of the .222 Remington Magnum. The .222 Remington Magnum provides about 5% more usable (below the neck) case capacity than the most popular member of the family, the NATO 5.56×45mm (.223 Remington). To make the .204 Ruger, the .222 Remington Magnum case was necked down to .204 inches (5 mm) and its shoulder moved forward and angle increased to 30 degrees. Bullets available in .204 caliber range from 24 to 55 grains (1.55 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weatherby Mark V
The Weatherby Mark V is a centerfire, bolt-action rifle manufactured by Weatherby of Sheridan, Wyoming. The rifle was introduced in 1957 by Weatherby and was designed to safely contain the high pressures associated with the Weatherby line of high performance cartridges. It is the flagship rifle of the Weatherby line of firearms. The Weatherby Mark V rifles are considered prestigious or luxury firearms by many. This is due in part to Roy Weatherby who presented the rifles to royalty, politicians, gun writers and actors including Prince Abdorreza Pahlavi of Iran, Generals James Doolittle (USAF) and Chuck Yeager (USAF), Jack O'Connor, Warren Page, Elgin Gates and Lorne Greene and was able to use this fact as a marketing tool. Early development Ever since Roy Weatherby began manufacturing rifles he had to rely on a third party to provide the actions for his rifles. Beginning in 1949 Weatherby began building his rifles around the FN Belgian Mauser action. In 1955 Schultz & Larson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weatherby
Weatherby, Inc. is an American gun manufacturer founded in 1945 by Roy Weatherby. The company is best known for its high-powered magnum cartridges, such as the .257 Weatherby Magnum, .270 Weatherby Magnum, .300 Weatherby Magnum, .340 Weatherby Magnum and the .460 Weatherby Magnum. The company's headquarters is based in Sheridan, Wyoming. History The original production rifles by Roy Weatherby were built on commercial Mauser actions manufactured by FN, Brevex (magnum), and Mathieu (left hand). Weatherby would build a custom rifle from a customer's specifications for bespoke rifles, using any action the customer requested - provided the action was strong enough to tolerate the pressures for their desired cartridge. Weatherby manufactured his rifles for many years at his small facility in South Gate, California, until 1956, when he contracted with Sako to continue building his firearms based on the Weatherby-FN Mauser actions. Weatherby still produced some custom rifles in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifled barrel, the distance is measured between opposing lands or between opposing grooves; groove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head ( centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin ( pinfire, now obsolet ...

Tikka M55
The Tikka M55 (originally Tikka M76 and also Tikka LSA55) is a Finnish rifle designed by Finnish firearms company Tikkakoski in 1967–1968. M55 was the first centerfire rifle action designed by Tikkakoski, and it was manufactured from 1968 to 1989. Tikkakoski also developed a long action rifle based on the M55, called Tikka M65. The Tikka M55 was imported to the United States by Ithaca Gun Company. History Tikkakoski company, which had been under German ownership, was expropriated in 1944 and handed over to the Soviet Union in 1947 as ruled by the Moscow Armistice. Under the Soviet ownership, the firearms production was run down by the end of 1954. After a group of Finnish businessmen bought Tikkakoski company from the Soviet Union in 1957, the company started focusing again in firearms in 1963, and first prototypes of a repeating centerfire rifle were manufactured in 1967, and the final product, the production of which began in 1968, was named the M76. The M76 was the firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Special Air Service
The Special Air Service (SAS) is a special forces unit of the British Army. It was founded as a regiment in 1941 by David Stirling and in 1950, it was reconstituted as a corps. The unit specialises in a number of roles including counter-terrorism, hostage rescue, direct action and covert reconnaissance. Much of the information about the SAS is highly classified, and the unit is not commented on by either the British government or the Ministry of Defence due to the secrecy and sensitivity of its operations. The corps currently consists of the 22 Special Air Service Regiment, the regular component, as well as the 21 Special Air Service Regiment (Artists) (Reserve) and the 23 Special Air Service Regiment (Reserve), which are reserve units, all under the operational command of United Kingdom Special Forces (UKSF).

Counterterrorism
Counterterrorism (also spelled counter-terrorism), also known as anti-terrorism, incorporates the practices, military tactics, techniques, and strategies that governments, law enforcement, business, and intelligence agencies use to combat or eliminate terrorism. Counterterrorism strategies are a government's motivation to use the instruments of national power to defeat terrorists, the organizations they maintain, and the networks they contain. If definitions of terrorism are part of a broader insurgency, counterterrorism may employ counterinsurgency measures. The United States Armed Forces uses the term foreign internal defense for programs that support other countries' attempts to suppress insurgency, lawlessness, or subversion, or to reduce the conditions under which threats to national security may develop. History The first counter-terrorism body formed was the Special Irish Branch of the Metropolitan Police, later renamed the Special Branch after it expanded ...
