22 CB
The .22 CB Cap (Conical Bullet Cap), also known as the 6mm Flobert, is a more powerful version of the .22 BB Cap 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 cataloged in 1888, 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. In Europe, the cartridge is stil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Primer (firearms)
In firearms and artillery, the primer () is the chemical and/or device responsible for initiating the propellant combustion that will propel the projectiles out of the gun barrel. In early black powder guns such as muzzleloaders, the primer was essentially the same chemical as the main propellant (albeit usually in a finer-powdered form), but poured into an external flash pan, where it could be ignited by an ignition source such as a slow match or a flintlock, though some muzzleloaders have primers like cap gun caps. This external powder was connected through a small opening at the rear of the gun barrel that led to the main charge within the barrel. As gunpowder will not burn when wet, this made it difficult (or even impossible) to fire these types of weapons in rainy or humid conditions. Modern primers, by contrast, are more specialized and distinct from the main propellant they are designed to ignite. They are of two types, those using shock-sensitive chemicals, and those r ...

Rimfire Cartridges
Rimfire ammunition (also rim-fire) is a type of metallic cartridge used in firearms where the primer is located within a hollow circumferential rim protruding from the base of its casing. When fired, the gun's firing pin strikes and crushes the rim against the edge of the barrel breech, sparking the primer compound within the rim and igniting the propellant within the case. Invented in 1845 by Louis-Nicolas Flobert, the first rimfire metallic cartridge was the (also known as the 6mm Flobert) cartridge, which consisted of a percussion cap with a bullet attached to the top. While many other different cartridge priming methods have been tried since the early 19th century, such as teat-fire and pinfire, only small caliber rimfire ( .22caliber (5.6mm) or less) cartridges have survived to the present day with regular use. The .22Long Rifle rimfire cartridge, introduced in 1887, is by far the most common ammunition found in the world today in terms of units manufactured and sol ...

Pistol And Rifle Cartridges
A pistol is a type of handgun, characterised by a barrel with an integral chamber. The word "pistol" derives from the Middle French ''pistolet'' (), meaning a small gun or knife, and first appeared in the English language when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term to describe ''any'' type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol. The older single-shot and lever-action pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment. Fully-automatic machine pistols are uncommon in civilian usage because of their generally poor recoil-controllability (due to the lack of a buttstock) and strict laws and regulations governing their manufactur ...

List Of Rimfire Cartridges
Below is a list of rimfire cartridges'' (''RF), ordered by caliber, small to large. Rimfire ammunition is a type of metallic cartridge whose primer is located within a hollow circumferential rim protruding from the base of its casing. The most common rimfire cartridges are chambered for .17 caliber and .22 caliber. The bullet diameter for .17 caliber firearms generally measure .172 inch (4.37 mm), while the bullet diameter for .22 caliber firearms generally measure .222 inch (5.64 mm).

22 Hornet
The .22 Hornet or 5.6×36mmR Hornet is a varminting, game (hunting), small-game hunting, survival skills, survival and competition centerfire rifle cartridge commercially introduced in 1930. It is considerably more powerful than either the .22 WMR and the .17 HMR rimfire ammunition, rimfire cartridges, achieving a higher velocity with a bullet twice the weight of that used in the .17 HMR. The Hornet also differs significantly from these in that being a centerfire cartridge makes it Handloading, reloadable, and thus more versatile. It was also the smallest commercially available .22 caliber centerfire cartridge until the introduction of the FN 5.7×28mm. The .22 Hornet should not be confused with the 5.6x35mmR Vierling. As per C.I.P., the Hornet case has a longer shoulder length, case length and thicker rim than the Vierling. This makes it very difficult to chamber the higher pressure Hornet cartridge in a Vierling rifle. The .22 Hornet fills the gap between such popular Varm ...

22 Long Rifle
The .22 long rifle, also known as the .22 LR or 5.7×15mmR, is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of firearms including rifles, pistols, revolvers, and submachine guns. In terms of units sold, it is by far the most common ammunition that is manufactured and sold in the world. Common uses include hunting and shooting sports. Ammunition produced in .22 long rifle is effective at short ranges, has little recoil, and is inexpensive to purchase. These qualities make it ideal for plinking and marksmanship training. History American cartridge 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, render ...

22 Long
The .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 bullet and 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 reputation as a small game cartridge. In 1887, the .22 long case was combined with the heavier bullet of the .22 extra long of 1880 to produce the .22 long rifle, giving a longer overall length and a higher muzzle energy. 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. The one prominent survivor of the .22 long is the .22 CB long, a long-cased version of the .22 CB. The original .22 long loading used the same powder charge as the .22 long rifle, .22 long bullet was sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, charcoal (which is mostly carbon), and potassium nitrate, potassium nitrate (saltpeter). The sulfur and charcoal act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building Pipeline transport, pipelines, tunnels, and road#Construction, roads. Gunpowder is classified as a Explosive#Low, low explosive because of its relatively slow decomposition rate, low ignition temperature and consequently low brisance, brisance (breaking/shattering). Low explosives deflagration, deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonation, detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
