Join us as we explore the world of 5.7×28 ammo, from its ballistic capabilities to its storied past, and discover why this relatively new cartridge, weighing in the spectrum of grains, is capturing the interest of shooters around the globe.

5.7x28 ammo

The intriguing story of the 5.7x28mm cartridge begins in the late 1980s when NATO issued a request for a new type of ammunition. They sought something that could outperform the traditional 9mm and 5.56mm rounds in certain cases and select respects. This request ignited a response from the Belgian manufacturer FN Herstal, who set out to create a cartridge that could deliver increased range, improved accuracy, and enhanced terminal performance—an ambitious goal that would lead to the birth of the 5.7×28 ammo. Coupled with swift shipping, FN Herstal’s innovative approach resulted in the SS90 prototype, a round that boasted a lightweight, high-velocity projectile capable of piercing body armor.

The Evolution of 5.7×28 ammo: From Inception to Innovation

The American market caught wind of the potential of this new cartridge, leading FN Herstal to file a United States patent application. The introduction of the SS190 duty cartridge, also referred to as a “sb193” by those in the know, soon followed in a neat box package, solidifying 5.7x28mm’s place in the world of small arms ammunition. This cartridge featured a pointed steel penetrator and an aluminum core, all encased within a traditional copper jacket, providing the perfect profile for a high-velocity, armor-penetrating round—ideal for specific cases of order from law enforcement and military units, and even certain handguns.

The evolution of 5.7×28 ammo illustrates a commitment to innovation and a keen understanding of the modern shooter’s requirements. It is a testament to FN Herstal’s ability to respond to the changing landscape of ammunition demands with agility, foresight, and attention to all aspects of the customer experience, including the all-important aspect of shipping. As the 5.7x28mm round transitions from a specialist’s choice to a more widely-accepted option, its development story offers valuable insights into the future of ammunition technology and the continual quest for ballistic excellence.

The 5.7 bullets, faced its first major international test in the early 2000s when NATO initiated evaluations to consider standardizing a new PDW (Personal Defense Weapon) and cartridge. This would mark a notable shift from the established 9mm cartridge, which had been the go-to in most cases for sidearms, submachine guns, and most handguns.

The test results were promising for the 5.7 bullets, a rimfire round that demonstrated superior range and the ability to penetrate standard NATO CRISAT vests, a composite armor set designed to simulate a soldier wearing light body armor. Despite these impressive results, the road to standardization was met with obstacles. Notably, the German delegation raised objections to standardizing the caliber, citing a preference for the competing 4.6×30mm round.
