Developed by FN America and loaded by Fiocchi, the SS197SR represents the pinnacle of sporting-grade 5.7x28mm ammunition. This round is built around Hornady’s 40-grain V-Max polymer tip bullet, a proven design known for its explosive expansion and exceptional accuracy. Designed from the ground up to meet the needs of enthusiasts, competition shooters, and varmint hunters, the SS197SR is as consistent as it is lethal.
The 5.7x28mm cartridge was originally designed for military and law enforcement applications, but it has gained significant popularity among civilian shooters looking for high-velocity, low-recoil performance. With more firearms than ever chambered in 5.7—including the Five-seveN, Ruger-57, PSA Rock, and CMMG Banshee—the need for quality ammunition is higher than ever. The SS197SR delivers exactly that.
At its core is the Hornady V-Max projectile, a hollow point design enhanced with a polymer tip that initiates expansion upon impact. This makes it highly effective on varmints and small game, while still maintaining controlled fragmentation to reduce the risk of over-penetration in defensive scenarios. The bullet’s aerodynamic profile also contributes to flat trajectories and tight groupings, even at extended ranges.
Whether you’re zeroing optics, running timed drills, or clearing out pests, this ammunition performs at a level that experienced shooters demand.
Ballistic Consistency:
When fired from an FN Five-seveN pistol, the SS197SR reaches 1,738 feet per second, with approximately 268 foot-pounds of energy. When fired from a PS90 carbine or similar-length barrel, velocity increases to around 2,034 feet per second, delivering over 360 foot-pounds of energy at the muzzle.
The result is a cartridge that bridges the gap between traditional handgun rounds and small-caliber rifle cartridges—offering high speed and low recoil without sacrificing stopping power.
