Wildcat Cartridge
A wildcat cartridge, often shortened to wildcat, is a custom-made cartridge (weaponry), cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created as experimental variants to optimize a certain ballistic performance characteristic (such as the power, size, or efficiency) of an existing commercial cartridge, or may merely be intended as novelty items. Developing and using wildcat cartridges does not generally serve a purpose in military or law enforcement; it is more a hobby for serious sport 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. ...

Cold Forming
In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature at or near room temperature. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold work", cutting or grinding a formed object. Cold forming techniques are usually classified into four major groups: squeezing, bending, drawing, and shearing. They generally have the advantage of being simpler to carry out than hot working techniques. Unlike hot working, cold working causes the crystal grains and inclusions to distort following the flow of the metal; which may cause work hardening and anisotropic material properties. Work hardening makes the metal harder, stiffer, and stronger, but less plastic, and may cause cracks of the piece. The possible u ...

Blank (cartridge)
A blank is a firearm cartridge that, when fired, does not shoot a projectile like a bullet or pellet, but generates a muzzle flash and an explosive sound ( muzzle report) like a normal gunshot would. Firearms may need to be modified to allow a blank to cycle the action, and the shooter experiences less recoil with a blank than with a live round. Blanks are often used in prop guns for shooting simulations that have no need for ballistic results, but still demand light and sound effects, such as in historical reenactments, special effects for theatre, movie and television productions, combat training, for signaling (see starting pistol), and cowboy mounted shooting. Specialised blank cartridges are also used for their propellant force in fields as varied as construction, shooting sports, and fishing and general recreation. While blanks are less dangerous than live ammunition, they can still be dangerous and can still cause fatal injuries. Beside the explosive gases, any o ...

Cream Of Wheat
Cream of Wheat is an American brand of farina (food), farina, a type of breakfast porridge mix made from wheat middlings. It looks similar to grits, but is smoother in texture since it is made with ground wheat berry, wheat kernels instead of ground corn. It was first manufactured in the United States in 1893 by wheat millers in Grand Forks, North Dakota, and debuted at the 1893 World's Columbian Exposition in Chicago, Illinois. The rice-based Cream of Rice also forms part of the product line, and is often a recommended early food for infants and toddlers and for people who cannot tolerate wheat or gluten. Cream of Wheat was owned by Nabisco from 1961 to 2000 when Nabisco was bought by Kraft Foods Inc. B&G Foods acquired the Cream of Wheat and Cream of Rice brands from Kraft in January 2007. History After the Panic of 1893, the Diamond Milling Company in Grand Forks was faced with low prices and reduced demand for flour. Diamond's Scottish-born chief miller, Tom Amidon, p ...

Fire Forming
The term fire forming in firearms refers to the process of thermomechanically reshaping a metallic cartridge case to optimally fit a new chamber by firing it within that chamber.Glenn Newick, "The Ultimate in Rifle Accuracy", Stroger Publishing Company, 1989. This might expand a cartridge to a new size, such as a wildcat cartridge A wildcat cartridge, often shortened to wildcat, is a custom-made cartridge (weaponry), cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created as experimental variants to optimize a certain ballis ..., or just to the chamber of a specific gun. Fire forming a wildcat differs from the normal manufacturing process; in that it relies on firing a loaded cartridge of differing dimensions than the chamber which it is being fired in. After fire forming, the spent case will take on the new dimensions of the firearm's chamber. Fire forming is the final process in creating a wildcat or an improved cartridge. ...

Swage
Swaging () is a forging process in which the dimensions of an item are altered using dies into which the item is forced. Swaging is usually a cold working process, but also may be hot worked. The term swage may apply to the process (verb) or to a die or tool (noun) used in that process. Origin The term "swage" comes from the Old French term , meaning "decorative groove" or "ornamental moulding". Swages were originally tools used by blacksmiths to form metal into various shapes too intricate to make with a hammer alone. These have handles for holding or pegs for attaching to an anvil, and often a flat head for striking with a hammer. Swage blocks are anvil-like dies with various shapes forged into them, which are also used for forming metal. Swages called " fullers" are specific to making grooves in swords and knives. ''Swage'' is most often pronounced ( AHD format: swāj). Another (less common) pronunciation sometimes heard in the metalworking industries is (AHD forma ...

Internal Ballistics
Internal ballistics (also interior ballistics), a subfield of ballistics, is the study of the propulsion of a projectile. In guns, internal ballistics covers the time from the propellant's ignition until the projectile exits the gun barrel. The study of internal ballistics is important to designers and users of firearms of all types, from small-bore rifles and pistols, to artillery. For rocket-propelled projectiles, internal ballistics covers the period during which a rocket motor is providing thrust. General concepts Interior ballistics can be considered in three time periods: *Lock time - the time from sear release until the primer is struck *Ignition time - the time from when the primer is struck until the projectile starts to move *Barrel time - the time from when the projectile starts to move until it exits the barrel. The burning firearm propellant produces energy in the form of hot gases that raise the chamber pressure which applies a force on the base of the projectile, ...

45 ACP
The .45 ACP (Automatic Colt Pistol), also known as .45 Auto, .45 Automatic, or 11.43×23mm is a Rim (firearms)#Rimless, rimless straight-walled handgun Cartridge (firearms), cartridge designed by John Moses Browning in 1904, for use in his prototype Colt's Manufacturing Company, Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun cartridge. The standard-issue military .45 ACP cartridge uses a round-nose bullet at approximately fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-loading
A semi-automatic firearm, also called a self-loading or autoloading firearm (automatic firearm, fully automatic and selective fire firearms are also variations on repeating firearm#Autoloading, self-loading firearms), is a repeating firearm whose firearm action, action mechanism automatically loads a following round of cartridge (firearms), cartridge into the chamber (firearms), chamber and prepares it for subsequent firing, but requires the shooter to manually actuate the Trigger (firearms), 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 gun barrel#Bore, bore) to unlock and move the bolt (firearms), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handgun
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long gun, long barreled gun (i.e., carbine, rifle, shotgun, submachine gun, or machine gun) which typically is intended to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols. Before commercial mass production, handguns were often considered a badge of office — comparable to a ceremonial weapon, ceremonial sword – as they had limited utility and were more expensive than the long barreled guns of the era. In 1836, Samuel Colt patented the Colt Paterson, the first practical mass-produced revolver, which was capable of firing five shots repeating firearm, in rapid succession and quickly became a popular personal weapon, giving rise to ...
