5.7×28mm sporting cartridges. Contents.History DevelopmentThe 5.7×28mm cartridge was designed in response to requests for a replacement for the cartridge.
According to the NATO requirement, the new cartridge was to have greater range, accuracy, and than the 9×19mm cartridge. Additionally, it was to be capable of penetrating. Responded to the NATO requirement by developing the 5.7×28mm cartridge and two associated weapons: the FN P90 (PDW) and FN Five-seven pistol.The original 5.7×28mm cartridge, called the SS90, was introduced in 1990.
It used a 1.5 (23 ) plastic-core, which was propelled at a of roughly 850 (2,800 ) when fired from the P90. A United States for the projectile design used in the SS90 was filed by FN's Jean-Paul Denis and Marc Neuforge in 1989. Patent 5,012,743 ('High-Performance Projectile') was received in 1991. 5.7×28mm SS196SR with a quarter a and rulerThe 5.7×28mm SS90 cartridge was discontinued, and replaced, in 1993, with the 5.7×28mm SS190. The SS190 uses a 2.7-mm (0.11 in) shorter projectile with a weight of 2.0 g (31 grains), which has, when fired from the P90, a of roughly 715 m/s (2,350 ft/s). The shorter length of the SS190 projectile allows it to be more conveniently used in the 5.7×28mm FN Five-seven pistol, which was also being developed at that time.In 1993, FN introduced a modified version of the P90 with a magazine adapted to use the SS190 cartridge.

Several specialized 5.7×28mm varieties were also developed alongside the SS190, such as the L191 round and the SB193 bullet for sound-suppressed use. The 5.7×28mm chambered FN Five-seven pistol then went into production in 1998. NATO evaluationIn 2002 and 2003, NATO conducted a series of tests with the intention of standardizing a cartridge as a replacement for the 9×19mm Parabellum.
The tests compared the relative merits of the 5.7×28mm cartridge and the cartridge, which was created by German manufacturer as a competitor to the 5.7×28mm. The results of the NATO tests were analyzed by a group formed of experts from Canada, France, the United Kingdom, and the United States, and the group's conclusion was that the 5.7×28mm was 'undoubtedly' the more efficient cartridge.Among other points, the NATO group cited superior effectiveness (27 percent greater) for the 5.7×28mm against unprotected targets and equal effectiveness against protected targets. It also cited less sensitivity to extreme temperatures for the 5.7×28mm, and cited a greater potential risk of barrel erosion with the 4.6×30mm. In addition, the group pointed out that 5.7×28mm is close to the by its design and manufacture process, allowing it to be manufactured on existing production lines. The group also noted that 5.7×28mm firearms had existed for a longer period of time than 4.6×30mm firearms, and that the 5.7×28mm FN Five-seven pistol was already in production at that time, while the 4.6×30mm pistol was a new concept.However, the German delegation and others rejected the NATO recommendation that 5.7×28mm be standardized, halting the standardization process indefinitely.
As a result, both the 4.6×30mm and 5.7×28mm cartridges (and the associated weapons) have been independently adopted by various NATO countries, according to preference; both the P90 and Five-seven are currently in service with military and police forces in over 40 nations throughout the world. PresentIn 2004, the SS192 cartridge was introduced to civilian shooters alongside the new IOM variant of the Five-seven pistol. After being met with controversy, the SS192 variety was discontinued in the same year, and in 2005 the SS196SR variety was introduced using a 2.6 g (40 grain) V-Max projectile. The SS196 was also quickly discontinued in favor of the newer SS195LF and SS197SR varieties, which are currently offered to civilian shooters for use in 5.7×28mm firearms, followed by the SS198LF variety, which is currently produced but is restricted by FN to military and law enforcement customers.FN's 5.7×28mm ammunition types were briefly manufactured by -, but today they are made by in Belgium and (since 2006) in the United States. In 2009, the added 5.7×28mm firearms to its NRA Tactical Police Competition standards, allowing law enforcement agencies to compete in this event using 5.7×28mm firearms. Starting in 2012, Federal began producing a new 5.7×28mm round for civilian shooters, designated the AE5728A. Design detailsThe 5.7×28mm cartridge was designed by specifically for use in the FN P90 personal defense weapon and FN Five-seven pistol.
Subsequently, it has been used in a number of other weapons, such as the FN PS90 carbine and the AR-57, an upper for and rifles. The can be configured for the 5.7×28mm cartridge by changing the barrel and magazine groups. Excel Arms has developed four firearms chambered in 5.7×28mm, and MasterPiece Arms offers three different 5.7×28mm firearms.The 5.7×28mm cartridge weighs 6.0 grams (93 )—roughly half as much as a typical 9×19mm Parabellum cartridge—making extra ammunition less burdensome, or allowing more ammunition to be carried for the same weight. Since the 5.7×28mm cartridge also has a relatively small diameter, a relatively high number of cartridges can be contained in a. The cartridge has a loud and produces considerable (when fired from a pistol), but it has roughly 30 percent less than the 9×19mm cartridge, improving. Due to its high velocity, the 5.7×28mm also exhibits an exceptionally flat.One of the design intents of the SS190 variety of this cartridge was that it have the ability to penetrate —such as the NATO vest—that will stop conventional pistol bullets. Fired from the P90, the SS190 is capable of penetrating the CRISAT vest at a range of 200 m (219 ), or a Kevlar vest at the same range.
However, sporting variants of the 5.7×28mm are classified by the U.S. (ATF) as not armor-piercing. From left to right:, 5.7×28mm, and a 2.75-inch (70 mm) and 3-inch (76 mm).According to FN, the 5.7×28mm cartridge has an effective range of 200 m (219 yd) and a maximum range of 1,800 m (1,969 yd) when fired from the P90, and an effective range of 50 m (55 yd) and a maximum range of 1,510 m (1,651 yd) when fired from the Five-seven. In testing, the SS190 and similar 5.7×28mm projectiles consistently turn base over point ('tumble') as they pass through and other media, using the 21.6-mm (.85 in) projectile length to create a larger wound cavity.
However, some are skeptical of the bullet's, and it is a subject of debate among civilian shooters in the United States.The 5.7×28mm projectile potentially poses less risk of than conventional pistol bullets, because the projectile design limits overpenetration, as well as risk of. The lightweight projectile also poses less risk of collateral damage in the event of a miss, because it loses much of its after traveling only 400 m (437 yd), whereas a conventional pistol bullet such as the 9×19mm retains significant energy beyond 800 m (875 yd). L191 cartridge and box L191 tracer The L191 (also formerly called the SS191) is a cartridge designed for easier bullet spotting in dim light.

Combustible chemicals packed in the rear of the L191 projectile create a light trail visible up to 200 m (219 yd). The L191 has been manufactured with red and red-on-black tips. The performance and trajectory of the L191 is identical to the SS190. For this reason, it is also classified by the ATF as armor-piercing handgun ammunition, and its sale is currently restricted by FN to military and law enforcement customers.
SS192 hollow-point The SS192 was discontinued in late 2004. It used a 1.8 g (28 grain) hollow point bullet with a copper jacket and an aluminum core.
The projectile had a length of 21.6 mm (.85 in). It had an unmarked hollow nose with a depth of 7.6 mm (0.3 in) and a 0.8-mm (0.03 in) opening. The SS192 was classified by the ATF as not armor-piercing, and in testing by FNH USA it did not penetrate a Level IIIA vest when fired from the Five-seven. SB193 subsonic The SB193 (also formerly called the SS193) is a speed subsonic cartridge featuring a 3.6-g (55 grain) Sierra Game King FMJBT (FMJ ) projectile. The SB193's low muzzle velocity eliminates the distinctive 'crack' created by supersonic rounds, and when used in conjunction with a sound suppressor, the muzzle report is also reduced. Due to the greatly decreased muzzle velocity, the SB193 benefits from a slightly reduced recoil force of 1.3.
The SB193 can be identified by its white tip color. Its sale is currently restricted by FN to military and law enforcement customers.
T194 training The T194 training round was discontinued in 2002. It could be considered an early version of the SS192 or SS195. It used the same 1.8-g (28 grain) -jacketed aluminum core bullet, propelled at the same muzzle velocity.
It had a green tip. SS195LF cartridge and box SS195LF (lead free) The SS195LF is a commercially available cartridge that features a -free primer and produces ballistics similar to the SS192 round, which it replaced in late 2004. It uses the same 1.8-g (28 grain) copper-jacketed aluminum core bullet as the SS192, and it can be identified by the unmarked, hollow void at the tip and the silver-colored primer. The SS195 is classified by the ATF as not armor-piercing, and it is currently manufactured by FN Herstal in Belgium.
SS196SR (sporting round) The SS196SR was introduced in 2005 and it is now discontinued in favor of the SS197SR cartridge. It featured a lead core 2.6-g (40 grain) Hornady V-Max bullet which it propelled at a muzzle velocity of roughly 500 m/s (1,650 ft/s) when fired from the Five-seven. The polycarbonate tip used in the V-Max bullet acted as a wedge, enhancing expansion of the bullet. The SS196 was classified by the ATF as not armor-piercing, and in testing by FNH USA it did not penetrate a Level II vest when fired from the Five-seven. The SS196 could be identified by its red polymer tip.
SS197SR (sporting round). SS197SR (left) and (right) The SS197SR is currently offered to civilian shooters in addition to the SS195LF.
It uses the same lead core 2.6-g (40 grain) Hornady V-Max projectile as the SS196SR, but it is loaded for a muzzle velocity roughly 30-m/s (100 ft/s) higher. The projectile has a blue-colored polymer tip instead of the red color used in the SS196 projectile tip. The SS197 has been manufactured by Fiocchi, under contract for FN Herstal, since 2006 and it is distributed in the United States. SS198LF (lead free) The SS198LF uses the same lead-free projectile and primer as the SS195LF, but propels it at roughly a 30-m/s (100 ft/s) higher muzzle velocity.
It has a green painted tip, and its sale is currently restricted by FN to military and law enforcement customers. American Eagle (AE5728A) TMJ Since 2012, Federal Cartridge Company produces a 5.7×28mm round under their American Eagle brand. Designated the AE5728A, this cartridge uses a 40-grain (TMJ) projectile, that is atypical in that it does not use a copper plated bullet; sectioned pictures show a very thick full copper jacket. The AE5728A casings are of FN manufacture, and the muzzle velocity is slightly lower than that of the SS197SR. Non-FN ammunition Elite Ammunition manufactures a wide variety of reloaded 5.7×28mm ammunition offerings. Belgian ammunition manufacturer VBR-Belgium has also developed specialized 5.7×28mm projectiles designed for armor penetration and controlled fragmentation.
Is possible with 5.7×28mm ammunition, and 5.7-mm (.224 in) bullets are widely available due to use in and cartridges. Handloaders have noted that the 5.7×28mm cartridge is very sensitive to small changes in powder charge or overall length (OAL) with a bullet inserted. Bullets weighing 2.6 g (40 grains) or less are recommended for optimal use in 5.7×28mm applications, but the 1:231 mm (1:9.1 in) rifling twist rate (distance the bullet must travel to complete one full revolution) used in the firearms' barrels will stabilize bullets weighing up to 4.5 g (70 grains).
