Fiocchi recently announced the availability of its latest 5.7x28 mm cartridge in the company’s Range Dynamics series.

The new subsonic ammunition joins two 5.7x28 mm cartridge models introduced by Fiocchi at SHOT Show 2023.

Sporting a 62-grain full-metal-jacket bullet, Fiocchi’s new Range Dynamics Subsonic 5.7x28 mm ammunition is a solid option for high-volume suppressed or un-suppressed shooting at the range.

Available in 50-round boxes, Range Dynamics Subsonic 5.7x28 mm ammo is ideal for personal defense carbine training and semi-automatic pistol use. The new load rounds out Fiocchi’s 5.7x28 mm lineup that includes the 35-grain Hyperformance jacketed frangible, along with the Hyperformance 40-grain hollow-point cartridges.
