Fiocchi 57SUB62 5.7x28mm 62gr Subsonic FMJ Ammo 50rd Box

The Fiocchi 57SUB62 Range Dynamics delivers consistent subsonic performance in the 5.7x28mm platform, reducing noise signature while maintaining reliable cycling. This 62-grain full metal jacket ammunition provides shooters with an effective training and tactical option that operates below the sound barrier. Engineered for suppressed firearms, this load eliminates the sonic crack associated with standard velocity rounds.

What Makes This Different

Unlike standard 5.7x28mm loads that exceed 2,000 fps, this subsonic variant maintains velocities around 1,050 fps for significantly reduced noise levels. The heavier 62-grain projectile compensates for the reduced velocity, delivering improved terminal ballistics compared to lighter subsonic alternatives. Fiocchi's precision manufacturing ensures consistent powder charges and reliable ignition across temperature ranges.

Key Features

• 62-grain full metal jacket bullet optimized for subsonic velocities
• Boxer-primed brass cases suitable for reloading applications
• Consistent muzzle velocity around 1,050 fps from 10.4-inch barrels
• Reduced noise signature ideal for suppressed firearms
• Non-corrosive powder and primers for extended storage life
• Compatible with FN Five-seveN, PS90, and AR-57 platforms
• Packaged in 50-round boxes with 10 boxes per case (500 rounds total)

This ammunition excels in training environments where noise reduction is prioritized, particularly on indoor ranges or in sound-sensitive areas. The subsonic velocity eliminates the supersonic crack while maintaining sufficient energy for target engagement at typical defensive distances. Law enforcement and military units appreciate the tactical advantage of reduced acoustic signature during operations. The full metal jacket construction ensures reliable feeding and ejection across various 5.7x28mm firearms.
