5.7x28 Ammo

About 5.7x28mm Ammo

First introduced in 1990, the original 5.7×28 cartridge was initially called SS90 ammo and designed by two FN Herstal employees, Jean-Paul Denis, and Marc Neuforge.

Their goal was to replace the 9mm Luger cartridge for personal-defense firearms with greater range, accuracy, and terminal performance.

Although it's not widely considered a heavy-hitting caliber, 5.7x28 ammo is compact, accurate, and produces a light recoil.

Additionally, thanks to the standard extended magazine capacity for weapons chambered in 5.7 ammo, it's also a good choice for personal protection.

5.7x28 ammo features a bottleneck design, with a small 5.7mm diameter projectile and a high velocity of around 2,300 feet per second.

The ammunition has since been adopted by several military and law enforcement agencies. It is also commonly used by civilian firearm owners for target shooting and personal defense.

Over the years, 5.7x28mm ammo has become increasingly popular throughout the firearms community.

It is available in various loads from several major ammunition manufacturers, including FN Herstal, Federal American Eagle, and Speer Ammunition.
