The Fiocchi Range Dynamics 5.7x28mm 62 grain subsonic ammunition is engineered for quiet performance, reliable cycling, and consistent accuracy. Designed specifically for shooters seeking reduced noise signature with subsonic velocities, this loading is ideal for suppressed firearms and range training where reduced report matters.
Fiocchi’s Range Dynamics line focuses on delivering consistent performance with a clean shooting experience. This 62 grain subsonic load travels below the speed of sound to help reduce muzzle report while retaining reliable accuracy and dependable function in compatible platforms.
Understanding the ballistic differences between subsonic and supersonic 5.7x28mm ammunition can help you choose the best load for your use case — whether it’s suppressed shooting, range training, or general target practice.
Subsonic ammunition travels below approximately 1,100 fps (the speed of sound), which reduces the sonic crack traditionally associated with supersonic rounds. In calibers like 5.7x28mm, subsonic loads are ideal for use with sound suppressors, creating a smoother, quieter shooting experience without sacrificing feeding reliability.
Whether you're testing patterns, training on a suppressed firearm, or seeking reduced noise at the range, this Fiocchi subsonic load provides balanced performance with predictable function.
