FN 5.7×28mm
The FN 5.7×28mm (designated as the 5.7×28 by the C.I.P. and FN 5.7×28mm NATO) is a small-caliber, high-velocity, smokeless-powder, rebated, non-tapered, bottleneck, centerfire cartridge designed for pistols and personal defense weapons (PDW) uses, manufactured by FN Herstal. It is similar in length to the .22 WMR and .22 Hornet. Unlike many new cartridges, it has no parent case; the complete package was developed from scratch by FN. The 5.7×28mm was developed in conjunction with the FN P90 PDW and later the FN Five-seven pistol in response to NATO requests as a replacement for the 9×19mm Parabellum cartridge. In 2002 and 2003, NATO conducted a series of tests to find a replacement. The tests compared the relative merits of the 5.7×28mm cartridge and the 4.6×30mm cartridge, which was created by Heckler & Koch as a competitor to the 5.7×28mm. The NATO group subsequently recommended the 5.7×28mm cartridge, citing superior performance in testing, but the German del ...

Pistol
A pistol is a type of handgun, characterised by a gun barrel, barrel with an integral chamber (firearms), 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 (firearms), cylinder housing multiple chambers) and the pocket gun, pocket-sized derringers (which are often multiple-barrel firearm, 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 l ...

Muzzle Velocity
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/ shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Several factors, including the type of firearm, the cartridge, and the barrel length, determine the bullet's muzzle velocity. Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''super ...

Heckler & Koch
Heckler & Koch GmbH (HK or H&K; ) is a German firearms manufacturer that produces handguns, rifles, submachine guns, and grenade launchers. The company is located in Oberndorf am Neckar, Baden-Württemberg and also has subsidiaries in the United Kingdom, France, and the United States. Heckler & Koch was founded in 1949 by former Mauser engineers Edmund Heckler, Theodor Koch, and Alex Seidel, who founded the company out of the shuttered Mauser factory in Oberndorf. The company initially produced machine tool and metal parts until 1956 when, in response to a contract for a new service rifle, HK developed the Heckler & Koch G3. The success of the G3 rifle prompted HK to transition to the defense industry. HK was owned by Royal Ordnance from 1991 to 2002, and is currently part of the Heckler & Koch Group, comprising Heckler & Koch GmbH, Heckler & Koch Defense, NSAF Ltd., and Heckler & Koch France SAS.

HK 4
The HK4 is a pocket pistol, first introduced by Heckler & Koch in either 1964 or 1967. It was distinctive for allowing shooters to swap barrels chambered for different cartridges without tools and for having a durable but light hard-anodized aluminum-alloy frame. Design The HK4 is largely a refined Mauser HSc The Mauser HSc is a 7.65mm pistol introduced in Nazi Germany during World War II, and manufactured until 1977. The designation HSc stood for ''Hahn Selbstspanner'' ("self-cocking hammer") ''Pistole'', third and final design ''"C"''. Production wa ... self-loading pistol. Heckler & Koch were familiar with the HSc design as many of the Heckler & Koch company founders were employees of the Mauser-Werke Oberndorf A.G. company pre- and post-WW2. Similar to the HSc, the HK4 utilizes a straight blowback action, with a double-action trigger and a slide-mounted safety. Additionally, the pistol has a internal safety mechanism that will keep the firing pin misaligned from the hammer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
9×19mm Parabellum
The 9×19mm Parabellum (also known as 9mm Luger, 9mm NATO or simply 9mm) is a Rim (firearms)#Rimless, rimless, Centerfire ammunition, centerfire, tapered cartridge (firearms), firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, it is widely considered the most popular handgun and submachine gun cartridge due to its low cost, adequate stopping power and extensive availability. Since the cartridge was designed for the Luger pistol, Luger semi-automatic pistol, it has been given the designation of ''9mm Luger'' by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) and the (CIP). A 2007 US survey concluded that "about 60 percent of the firearms in use by police are 9mm [Parabellum]" and credited 9×19mm Parabellum pistol sales with making semiautomatic pistols more popular than revolvers.Adler, Jerry, et al.

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 ...

Centerfire
Two rounds of .357 Magnum, a centerfire cartridge; notice the circular primer in the center A center-fire (or centerfire) is a type of metallic cartridge used in firearms, where the 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 the cartridge. Centerfire cartridges have supplanted the rimfire cartridge, with the exception of a few small calibers. The majority of today's handguns, rifles, and shotguns use centerfire ammunition, with the exception of some .17 caliber, .20 caliber, and .22 caliber rimfire handgun and rifle cartridges, a few small-bore/gauge shotgun shells (intended mainly for use in pest control), and a handful of antiquated rimfire and pinfire cartridges for various firearm actions.

Cartridge (firearms)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a '' blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that ...
