Unsafe Firearm And Cartridge Combinations
Unsafe firearm and cartridge combinations are combinations of firearms and cartridges which can cause an unsafe condition for the shooter when firing. The unsafe condition can arise due to use of a cartridge intended for another chambering (see ''SAAMI list'' below), or using overpressure ammunition in a firearm not designed for such pressures, or using explosive (tampered) ammunition, or otherwise unsafe ammunition. Another example of an unsafe firearm and cartridge combination is the firing of saboted rounds in firearms with muzzle devices (such as a flash suppressor, muzzle brake, or choke) unless the muzzle device has been specifically designed for safe use with that particular type of saboted ammunition (see ''Saboted ammunition and muzzle devices'' below). SAAMI listing The U.S. based Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) has listed a number of known unsafe firearm chamber and cartridge combinations which can happen due to mixing of diffe ...

Firearm
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
300 AAC Blackout
The .300 AAC Blackout (designated as the 300 BLK by the SAAMI and 300 AAC Blackout by the C.I.P. or 300 AAC Blackout'' C.I.P. TDCC sheet 300 ACC Blackout/ref>), also known as 7.62×35mm, is an intermediate cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. The cartridge yields increased performance in shorter barrels and effective subsonic performance for suppressor use when compared to 5.56mm NATO. The 300 AAC Blackout utilizes standard 5.56mm NATO magazines and components with the exception of the barrel. History While 5.56×45mm NATO has enjoyed widespread acceptance in military circles, the nature of the missions encountered by some special operations groups often demand a round that provides better performance than that available in the high-energy, standard velocity rounds, and subsonic performance greater than standard 9×19mm Parabellum (the ubiquitous pistol and submachine gun) round. To meet this demand, AAC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

22 Short
.22 Short is a variety of .22 caliber (5.6 mm) rimfire ammunition. Developed in 1857 for the first Smith & Wesson revolver, the .22 rimfire was the first American metallic cartridge. The original loading was a bullet and of black powder. The original .22 rimfire cartridge was renamed .22 Short with the introduction of the .22 Long in 1871. Developed for self defense, the modern .22 Short, though still used in a few pocket pistols and mini-revolvers, is mainly used as a quiet round for practice by the recreational shooter. The .22 Short was popularly used in shooting galleries at fairs and arcades; several rifle makers produced " gallery" models for .22 Short exclusively. Due to its low recoil and good inherent accuracy, the .22 Short was used for the Olympic 25 meter rapid fire pistol event until 2004, and they were allowed in the shooting part of modern pentathlon competitions before they switched to air pistols. Several makes of starter pistols use .22 Short blank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
