Heeled Bullet
A heeled bullet is a specific design of bullet where the internal diameter of the barrel is often, but not always, the same diameter as the cartridge case, and the bullet has a step at the rear to allow it to fit inside the case. Heeled bullets mostly disappeared with the advent of smokeless powder cartridges, though older rimfire designs, such as the .22 caliber rimfire cartridges, still use heeled bullets, and many cartridges that date back to the black powder era still reflect their heeled bullet origins in their caliber designations. Reasons for change The heeled bullet design has many advantages, mainly when coupled with the straight or slightly tapered walled cases it appeared in. For pistols, converting a cap and ball revolver to use cartridges was as simple as cutting off part of the rear of the cylinder, replacing it with a frame-mounted ring, and changing the hammer. It also made new revolvers easier and cheaper to manufacture as the chambers could simply be drilled strai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grease (lubricant)
Grease is a solid or semisolid lubricant formed as a dispersion of thickening agents in a liquid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil. A common feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease. This change in viscosity is called shear thinning. Grease is sometimes used to describe lubricating materials that are simply soft solids or high viscosity liquids, but these materials do not exhibit the shear-thinning properties characteristic of the classical grease. For example, petroleum jellies such as Vaseline are not generally classified as greases. Greases are applied to mechanisms that can be lubricated only infrequently and where a lubricating oil would not stay in position. They also act as sealants to prevent ingress of water and incompressible mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

38 ACP
The .38 ACP (Automatic Colt Pistol), also known as the .38 Auto or 9x23mmSR, is a semi-rimmed pistol cartridge that was introduced at the turn of the 20th century for the John Browning-designed Colt M1900. It was first used in Colt's Model 1897 prototype, which he did not produce. The metric designation for the round is 9×23mm SR (semi-rimmed), which is not to be confused with other 9×23mm cartridges. History Initial loadings of this cartridge were quite powerful. Reported ballistics for the first commercial loads were a 130-grain bullet at , and some experimental loads ran as high as .Article in the April 19, 1900, issue of ''Shooting and Fishing,'' quoted in Belden, C.T and Haven, ''A History of the Colt Revolver'' (1940) However, these ballistics proved too violent for the Colt Model 1900 pistol, and velocities were soon lowered to below . Subsequent commercial loadings varied considerably in power. For example, Hugh B.C. Pollard, writing in ''Automatic Pistols'' in 1920, ...

38 Super
The .38 Super, also known as .38 Super +P, .38 Super Auto, .38 Super Automatic, .38 Super Automatic +P, or 9×23mmSR, is a pistol cartridge that fires a bullet. It was introduced in the late 1920s as a higher pressure loading of the .38 ACP, also known as .38 Auto. The older .38 ACP cartridge propels a bullet at , whereas the .38 Super pushes the same bullet at . The .38 Super has gained distinction as the caliber of choice for many top practical shooting competitors; it remains one of the dominant calibers in IPSC competition.Boatman, Robert H.: ''Living With the 1911: A Fresh Look at the Fighting Gun'', p. 15. Paladin Press, January 2005. Design The cartridge was designed for use in the M1911 pistol and was capable of penetrating automobile bodies of the late 1920s. When the .357 Magnum was introduced in 1935, this advantage of the .38 Super was no longer enough to lure police departments and officers from the traditional double-action revolver. The .38 Super retains the or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
38 Short Colt
The .38 Short Colt, also known as .38 SC, was a heeled bullet cartridge intended for metallic cartridge conversions of the cap and ball Colt 1851 Navy Revolver from the American Civil War era. Later, this cartridge was fitted with a diameter inside-lubricated bullet in the 125–135 grain range. Case Visually, it resembles a .38 S&W but the case dimensions are slightly different. The .38 Short Colt case is the parent to the .38 Long Colt and .38 Special. Remington is one of the few producers of this cartridge today with a 125 gr LRN bullet. Magtech produces this grain weight and Ten-x manufactures a 95 gr load, as well as blanks. This cartridge can be safely fired in revolvers chambered for .38 Special or .357 Magnum The .357 Smith & Wesson Magnum, .357 S&W Magnum, .357 Magnum, or 9×33mmR as it is known in unofficial metric designation, is a smokeless powder cartridge with a bullet diameter.

38 S&W
The .38 S&W, also commonly known as .38 S&W Short (it is sometimes referred to as .38 S&W Short to differentiate it from .38 Long Colt and .38 Special), 9×20mmR, .38 Colt NP (New Police), or .38/200, is a revolver cartridge developed by Smith & Wesson in 1877. Versions of the cartridge were the standard revolver cartridges of the British military from 1922 to 1963. Though similar in name, it is not interchangeable with the later .38 Special due to a different case shape and slightly larger bullet diameter. History The round was first introduced in 1877 for use in the S&W .38 Single Action. As standard for the era, it featured heeled bullet with the same diameter of bullet and case neck equal to .38 inch; later versions discarded the feature and downsized the bullet, but the designation didn't change. After World War I, the British military sought to replace pre-war revolvers with easier-to-handle weapons. Webley demonstrated a lighter version of their Mk III revolver with ...

Cowboy Action Shooting
Cowboy action shooting (CAS, also known as western action shooting, single action shooting, Cowboy 3 Gun, Western 3-gun) is a competitive shooting sport that originated in Southern California in the early 1980s, at the Coto de Caza Shooting Range in Orange County, California. Cowboy action shooting is now practiced in many places with several sanctioning organizations including the Single Action Shooting Society (SASS), Western Action Shootists Association (WASA), and National Congress of Old West Shooters (NCOWS), Single Action Shooting Australia (SASA), Western 3-Gun as well as others in the U.S. and other countries. CAS is a type of multigun match utilizing a combination of handgun(s), rifle(s), and/or shotgun(s) in a variety of " Old West-themed" courses of fire for time and accuracy. Participants must dress in appropriate theme or era "costume" as well as use gear and accessories as mandated by the respective sanctioning group rules. Firearms CAS requires competitors ...

22 BB
.22 BB Cap (Bulleted Breech Cap) also known as the 6mm Flobert, is a variety of .22 caliber rimfire ammunition. Invented by Louis-Nicolas Flobert in 1845, it was the first rimfire metallic cartridge. The .22 BB Cap and .22 CB Cap are interchangeable and are relatively quiet low velocity cartridges, designed for indoor target shooting. History Frenchman Louis-Nicolas Flobert invented the first rimfire metallic cartridge in 1845. His cartridge consisted of a percussion cap with a bullet attached to the top. Flobert then made what he called " parlor guns" for this cartridge, as these rifles and pistols were designed to be shot in indoor shooting parlors in large homes. Usually derived in the 6 mm and 9 mm calibres, it is since then called the Flobert cartridge, but it does not contain any powder; the only propellant substance contained in the cartridge is within the percussion cap.

22 CB
The .22 CB cap (conical breech cap) is a more powerful version of the .22 BB cap (aka: 6mm Flobert) rimfire metallic cartridge, which was invented by Louis-Nicolas Flobert in 1845. The .22 BB cap and .22 CB cap are interchangeable and are relatively quiet, low velocity cartridges, designed for indoor target shooting. History Designed to be a cross between the .22 BB and .22 Short, and first catalogued in around 1888 (though probably first made before that), it "managed to combine about all the disadvantages... f bothinto one generally useless cartridge",Barnes, p.273, ".22 CB Cap". being no more accurate than either while being noisier than the .22 BB cap, and penetrating much deeper, requiring a backstop as strong as for the .22 Short, thereby negating the CB cap's advantages for shooting indoors. American ammunition manufacturers dropped the .22 CB cap in the 1940s. In Europe, the .22 BB cap and .22 CB cap are both called "6mm Flobert" and are considered the same cartridge ...

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.
