Product Review

The FN 5.7x28mm Ammo (designated as the 5.7×28 by the C.I.P. and FN 5.7x28mm NATO) is a small-caliber, high-velocity, smokeless powder, rebated rim, bottlenecked centerfire cartridge designed for handgun and personal defense weapon (PDW) uses manufactured by FN Herstal. It is similar in length to the .22 WMR (5.7×27mm) and to some degree similar also to the .22 Hornet or .22 K-Hornet. Unlike many new cartridges, it has no parent case; the complete package was developed from scratch by FN.

5.7x28mm ammo

 

The 5.7x28mm Ammo was developed in conjunction with the FN P90 PDW and FN Five-seven pistol in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge. In 2002 and 2003, NATO conducted a series of tests with the intention of standardizing a PDW cartridge as a replacement for the 9×19mm Parabellum cartridge. 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 5.7x28mm Ammo, citing superior performance in testing, but the German delegation objected and the standardization process was halted until 2021 when it was officially adopted as a NATO standard STANAG 4509.

History Of The 5.7x28mm Ammo

Development

The 5.7x28mm Ammo was designed in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge. According to the NATO requirement, the new cartridge was to have greater range, accuracy, and terminal performance than the 9×19mm cartridge. Additionally, it was to be capable of penetrating body armor. FN Herstal responded to the NATO requirement by developing the 5.7x28mm Ammo and two associated weapons: the FN P90 personal defense weapon (PDW) and FN Five-seven pistol.

The original 5.7x28mm Ammo, called the SS90, was introduced in 1990. It used a 1.5 g (23 gr) plastic-core projectile, which was propelled at a muzzle velocity of roughly 850 m/s (2,800 ft/s; Mach 2.5) when fired from the P90. A United States patent application for the projectile design used in the SS90 was filed by FN’s Jean-Paul Denis and Marc Neuforge in 1989. U.S. Patent 5,012,743 (“High-Performance Projectile”) was received in 1991.

Design details Of 5.7x28mm Ammo For Sale

The 5.7x28mm Ammo was designed by FN Herstal 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 receiver for M16 and AR-15 rifles. The ST Kinetics CPW can be configured for the 5.7×28 ammo by changing the barrel and magazine groups. Excel Arms has developed four firearms chambered in 5.7×28mm, and MasterPiece Arms offers three different 5.7×28 ammo firearms.

5.7x28 amm

The 5.7×28 ammo weighs 6.0 grams (93 grains)—roughly two-thirds 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 5.7×28 ammo also has a relatively small diameter, a relatively high number of cartridges can be contained in a magazine. The cartridge has a loud report and produces considerable muzzle flash (when fired from a pistol), but it has roughly 30 percent less recoil than the 9×19mm cartridge, improving controllability. Due to its high velocity, the 5.7×28mm also exhibits an exceptionally flat trajectory.

Americans define the shoulder angle at alpha/2 ≈ 35 degrees. The common rifling twist rate for this cartridge is 1:228.6 mm (1:9 in), 8 grooves, Ø lands = 5.53 mm, Ø grooves = 5.62 mm, land width = 1.63 mm and the recommended primer type is small rifle.

According to the official C.I.P. (Commission Internationale Permanente pour l’Epreuve des Armes à Feu Portatives) rulings, the 5.7×28mm can handle up to 3,450 bar (345 MPa; 50,000 psi) Pmax (the nominal maximum) piezo pressure. In C.I.P. regulated countries, every rifle cartridge combination has to be proofed at 125% of this maximum C.I.P. pressure to be certified for sale to consumers, referred to as “PE”. This means that 5.7×28mm chambered arms in C.I.P. regulated countries are currently (2018) proof tested at 4,313 bar (431.3 MPa; 62,550 psi) PE piezo pressure.
