5.7x28 Ammo

Showing all 2 results

5.7×28 Ammo was created in conjunction with FN Five-seven pistol and FN P90 PDW due to NATO requests for a replacement for 9x19mm Parabellum ammunition. NATO conducted tests for 5.7×28 ammo in 2002 and 2003 to standardize a PDW cartridge to replace the 9x19mm Parabellum.

However, the German delegation opposed the recommendation, and the standardization process was stopped until 2021 when it was officially adopted by NATO standard STANAG 4509.

History of 5.7X28 Ammo

NATO requested that the 5.7×28 ammo be developed to replace its 9x19mm Parabellum cartridge. The NATO required that the new cartridge had greater range, accuracy, and terminal performance than its predecessor, the 9x19mm Parabellum cartridge. It was also necessary to penetrate body armor. FN Herstal developed the 5.7×28 ammo and two weapons to match the NATO requirements: the FN P90 personal defense weapon (PDW) and the FN Five-seven pistol.

In 1990, the SS90 was introduced with a 5.7×28 ammo cartridge. The cartridge used a 1.5g (23 gr) plastic-core projectile propelled at a muzzle velocity of approximately 850m/s (2800 ft/s; Mach 2.5) when fired from the P90. Jean-Paul Denis of FN and Marc Neuforge filed a U.S. patent application in 1989 for the projectile design used in the SS90. U.S. Patent 5,012,743 (“High-Performance Projectile”) was granted in 1991.

The 5.7x28mm SS190 can be fired from the FN P90 and penetrate the NATO CRISAT vest or a Level IIIA KEVLAR vest in a 200 m (219 yds).

In 1993, the 5.7x28mm SS90 cartridge, which was 5.7x28mm in size, was retired and replaced by the SS190, which is 5.7x28mm. The SS190 has a 2.7 mm (0.11 inch) shorter projectile, with a weight of 2.0 g (31 grams). It can be fired from the P90 at a muzzle velocity of approximately 716 m/s (2.350 ft/s; Mach 2.1). Because the SS190 projectile is shorter, it can be used more quickly in the 5.7x28mm FN Five-Seven pistol, also created at the time.

FN introduced a modified P90 in 1993 with a magazine that could be used with the SS190 cartridge. Along with the SS190, a variety of specialized 5.7×28 ammo was also created. These included the L191 tracer round for sound-suppressed applications and the subsonic SB193 Bullet. In 1998, the FN Five-seven pistol with 5.7×28 ammo was produced.

5.7X28 Ammo Design

FN Herstal designed the 5.7×28 ammo specifically for use with the FN P90 personal defence weapon and FN Five Seven pistol. It has since been used in various weapons, including the FN PS90 carbine, AR-57 upper receiver for M16 rifles and AR-15 rifles. You can modify the magazine groups and barrel of the ST Kinetics CPW to accommodate the 5.7x28mm cartridge. Excel Arms has four firearms that can be chambered with 5.7×28 ammunition. MasterPiece Arms also offers three guns that can take 5.7×28 ammo.

The 5.7x28mm cartridge is 6.0 grams (93 grain) in weight. This makes extra ammunition easier to carry or allows for more ammunition to be transported at the same weight. The magazine can hold many cartridges due to the small size of the 5.7x28mm ammo cartridge. It emits a loud sound and produces a lot of muzzle flash when fired from a pistol. However, it has approximately 30 percent less recoil than the 9x19mm cartridge, improving controllability. The 5.7×28 ammo has a very flat trajectory due to its high velocity.

The SS190 cartridge’s design goal was to be able to penetrate Kevlar protective Vests (such as NATO CRISAT vests) that will stop conventional pistol bullets. The SS190 can be fired from the P90 at a distance of 200 m (219 yds) or a Level IIIA KEVLAR vest at the same range. The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) classifies sporting variants of the 5.7x28mm as not armour-piercing.

According to FN, the 5.7×28 ammo cart has a range of 200 m (219 yds) and a maximum capacity of 1,800 m (1.969 yds) when fired from P90. It also has an effective range of 50 m (52.5 yds) and a maximum capacity of 1,510 m (1.651 yds) when fired from the Five-7. During testing, the SS190 and other similar 5.7x28mm projectiles turned base over point (“tumble”). They passed through ballistic gelatin and other media using the 21.6 mm (.85 inch) projectile length to create a more extensive wound cavity. Some are sceptical about the bullet’s final performance, which is still a topic of debate among civilian shooters in the United States.

Nato Evaluation of 5.7X28 Ammo

NATO carried out a series of tests in 2002 and 2003 to standardize a PDW cartridge to replace the 9x19mm Parabellum. The tests compared the relative merits of the 5.7×28 ammo and the HK 4.6x30mm ammunition, developed by Heckler & Koch in Germany to compete with the 5.7×28 ammunition.

A group of experts representing Canada, France and the United States analyzed the results of NATO tests and concluded that the 5.7x28mm cartridge was more efficient.

The NATO group also cited superior effectiveness (27% greater) for the NATO 5.7x28mm against targets that were not protected and equal effectiveness against protected targets. The 5.7x28mm was less sensitive to extreme temperatures, while the 4.6x30mm had a higher potential for barrel erosion.

Due to its design and manufacturing process, the 5.7x28mm ammo can be made on existing production lines. The group noted that 5.7x28mm firearms have been around longer than 4.6x30mm and that the 5.7x28mm FN Five-seven pistol had already been in production, while the 4.6x30mm Heckler & Koch UCP gun was a new concept.

The NATO recommendation to standardize 5.7×28 ammo was rejected by the German delegation and other members of the NATO group. This halted the standardization process indefinitely.

Both the 4.6x30mm- and 5.7x28mm-sized cartridges (and the associated weapons) were adopted independently by different NATO countries according to preference. The P90 and Five-seven are currently serving with military and police forces across more than 40 countries around the globe.
