Winchester Model 1912
The Winchester Model 1912 (also commonly known as the Model 12, or M12) is an internal-hammer pump-action shotgun with an external tube magazine. Popularly named the ''Perfect Repeater'' at its introduction, it largely set the standard for pump-action shotguns over its 51-year high-rate production life. From August 1912 until first discontinued by Winchester in May 1964, nearly two million Model 12 shotguns were produced in various grades and barrel lengths. Initially chambered for 20 gauge only, the 12 and 16 gauge versions came out in 1913 (first listed in the 1914 catalogs), and the 28 gauge version came out in 1934. A .410 version was never produced; instead, a scaled-down version of the Model 12 known as the Model 42, directly derived from scaled drawings of the Model 12, was produced in .410. Description The Model 1912 (shortened to Model 12 in 1919) was the next step from the Winchester Model 1897 hammer-fired shotgun, which in turn had evolved from the earlier Winchester ...

Winchester Model 70
The Winchester Model 70 is a bolt-action sporting rifle. It has an iconic place in American sporting culture and has been held in high regard by shooters since it was introduced in 1936, earning the moniker "The Rifleman's Rifle". The action has some design similarities to Mauser designs and it is a development of the earlier Winchester Model 54, itself based on a Mauser 98-type action. The Model 70 was originally manufactured by the Winchester Repeating Arms Company between 1936 and 1980. From the early 1980s until 2006, Winchester rifles were manufactured by U.S. Repeating Arms under an agreement with Olin Corporation, allowing USRA to use the Winchester name and logo. Model 70s were built in New Haven, Connecticut, from 1936 to 2006, when production ceased. In the fall of 2007, the Belgian company FN Herstal announced that Model 70 production would resume. As of 2012, new Winchester Model 70 rifles were being made by FN Herstal in Columbia, South Carolina. In 2013, assembly wa ...

Winchester Model 54
The Winchester Model 54 is a bolt-action rifle manufactured by the Winchester Repeating Arms Company. The 54 was the first successful production run civilian centerfire bolt action for Winchester; it was essentially a less-ornate derivative of the limited-production Model 51 "Imperial." Using a Mauser 98-type action, the Model 54 was produced until 1936 when, with some modifications, it was reintroduced as the Winchester Model 70. The Model 54 had a relatively heavy two stage trigger pull, which was greatly improved in the Model 70. Standard chamberings included the .22 Hornet, .220 Swift, .250-3000 Savage, .257 Roberts, .270 Winchester, 30-30 Winchester, .30-06 Springfield, 7x57mm Mauser, 7.65x53mm Argentine, and 9x57mm Mauser. Special order chamberings were made in .25-35 Winchester, .32 Winchester Special, .35 Whelen, and 38-55 Winchester. Introduced prior to the popularity of telescopic sights, it was intended for use with open or aperture sights, and the bolt throw m ...

Winchester Model 52
The Winchester Model 52 was a bolt-action .22-caliber target rifle introduced by the Winchester Repeating Arms Company in 1920. For many years it was the premier smallbore match rifle in the United States, if not the world. Known as the "King of the .22s," the Model 52 Sporter was ranked by ''Field & Stream'' as one of "the 50 best guns ever made" and described by Winchester historian Herbert Houze as "perfection in design." However, by the 1970s the World War I-era design was showing its age and had given way in top-level competition to newer match rifles from Walther and Anschütz; the costly-to-produce Model 52, which had long been a loss leader prestige product by that time, was finally discontinued when US Repeating Arms took over the manufacture of Winchester rifles from Olin Corporation in 1980. Origins During World War I Winchester's management determined that production of the Model 1885 Single Shot would not be resumed in centerfire chamberings after the war, nor in ...

Winchester Model 21
The Winchester Model 21 is a deluxe side by side shotgun. The shotgun's initial production run from 1931 through 1960 yielded approximately 30,000 guns. Winchester Repeating Arms Company ceased the main production line of this shotgun in 1960 and the Model 21 was sourced to the Winchester Custom Shop until the gun's retirement in 1991. New Winchester Model 21 production continues under license to Connecticut Shotgun Manufacturing Company. The Winchester Model 21 action is of a typical breech loading shotgun, commonly called a break or hinge action. Like all quality double guns, production is time-consuming due to the laborious process of joining the barrels to produce an identical convergence of shot. The Model 21 was Winchester's effort to make a quality side by side shotgun to rival those of high-end makers such as Parker and Fox; financial troubles plagued the gun's development until the Western Cartridge Company The Western Cartridge Company is an American manufacturer of ...

Slide Action
Pump action or slide action is a repeating firearm action that is operated manually by moving a sliding handguard on the gun's forestock. When shooting, the sliding forend is pulled rearward to eject any expended cartridge and typically to cock the hammer/ striker, and then pushed forward to load (''chamber'') a new cartridge into the chamber. Most pump-action firearms use an integral tubular magazine, although some do use detachable box magazines. Pump-action is typically associated with shotguns, although it has been used in rifles and other firearms as well. Because the forend is manipulated usually with the support hand, a pump-action gun is much faster than a bolt-action and somewhat faster than a lever-action, as it does not require the trigger hand to be removed from the trigger while reloading. Also because the action is cycled in a linear fashion, it creates less torque that can tilt and throw the gun off aim when repeat-firing rapidly. History The first slide acti ...

Winchester Model 1911
The Winchester Model 1911 SL Shotgun was a self-loading, recoil-operated shotgun produced by the Winchester Repeating Arms Company from 1911 to 1925. It was Winchester's first autoloading shotgun, but design flaws kept it from providing competition for the autoloading shotguns made by Remington Arms and Browning Arms Company. Description and development The Model 1911 SL (for "Self-Loading") shotgun was developed in 1911 by Thomas Crossley Johnson for the Winchester Repeating Arms Corporation. At the time, Winchester lacked an autoloading shotgun in its product offering, since the company had not accepted John Browning's conditions (he wanted to be paid on a royalty basis, without giving up his rights) for taking his 1898 autoloading design in production. The weapon rejected by Winchester was to become the Browning Auto-5 shotgun (also license-built as the Remington Model 11), and set the standard for autoloading shotgun designs until after World War II World War&n ...

Industrial Engineer
Industrial engineering is an engineering profession that is concerned with the optimization of complex processes, systems, or organizations by developing, improving and implementing integrated systems of people, money, knowledge, information and equipment. Industrial engineering is central to manufacturing operations. Industrial engineers use specialized knowledge and skills in the mathematical, physical and social sciences, together with the principles and methods of engineering analysis and design, to specify, predict, and evaluate the results obtained from systems and processes.Salvendy, Gabriel. Handbook of Industrial Engineering. John Wiley & Sons, Inc; 3rd edition p. 5 There are several industrial engineering principles followed in the manufacturing industry to ensure the effective flow of the systems, processes and operations. This includes Lean Manufacturing, Six Sigma, Information Systems, Process Capability and Define, Measure, Analyze, Improve and Control (DMAIC). T ...

Self-loading
A semi-automatic firearm, also called a self-loading or autoloading firearm (fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism ''automatically'' loads a following round of cartridge into the chamber (self-loading) and prepares it for subsequent firing, but requires the shooter to ''manually'' actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot (in the form of recoil or high-pressure gas expanding within the bore) to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, eac ...

Centerfire
Two rounds of .357 Magnum, a centerfire cartridge; notice the circular primer in the center A centerfire cartridge is a firearm metallic cartridge whose primer is located at the center of the base of its casing (i.e. "case head"). Unlike rimfire cartridges, the centerfire primer is typically a separate component seated into a recessed cavity (known as the ''primer pocket'') in the case head and is replaceable by reloading. Centerfire cartridges have supplanted the rimfire variety in all but the smallest cartridge sizes. The majority of today's handguns, rifles, and shotguns use centerfire ammunition, with the exception of a few .17 caliber, .20 caliber, and .22 caliber handgun and rifle cartridges, small-bore shotgun shells (intended for pest control), and a handful of antique (and mostly obsolete) cartridges. History An early form of centerfire ammunition, without a percussion cap, was invented between 1808 and 1812 by Jean Samuel Pauly. This was also the first f ...
