Fiocchi, a global leader in defensive, target, and hunting ammunition, has just announced availability of its latest 5.7x28mm cartridge. The new subsonic ammo joins two 5.7x28mm cartridge models introduced at the 2023 SHOT Show.

The newest Fiocchi 5.7x28mm cartridge is offered in the company’s Range Dynamics series. Sporting a 62-grain FMJ bullet, the Range Dynamics Subsonic is the ideal option for high-volume suppressed or un-suppressed fun on the range.

Available in 50-round boxes, Range Dynamics Subsonic is perfect for personal defense carbine training and semi-auto pistol use, and it rounds out Fiocchi’s 5.7x28mm lineup that includes the 35-grain Hyperformance jacketed frangible and the Hyperformance 40-grain hollow point cartridges.
