Fiocchi 57PT40 5.7x28mm 40gr Tipped Hollow Point Ammo 50rd Box

The Fiocchi 57PT40 Hyperformance delivers exceptional terminal performance in the specialized 5.7x28mm cartridge. This premium ammunition features a 40-grain tipped hollow point projectile engineered for rapid expansion and maximum energy transfer on target.

What Makes This Different

Fiocchi's Hyperformance line represents a significant advancement over standard 5.7x28mm ball ammunition. The tipped hollow point design initiates expansion at lower velocities than traditional hollow points while maintaining the flat trajectory and armor-penetrating characteristics that define the 5.7x28mm cartridge. Independent testing shows consistent expansion at velocities as low as 1,800 fps, compared to 2,100+ fps required by competing designs.

Key Features

• 40-grain tipped hollow point bullet for controlled expansion
• High-velocity loading achieving 2,034 fps from 4.8-inch barrel
• Boxer-primed brass cases suitable for reloading
• Compatible with FN Five-seveN, P90, PS90, and AR-57 platforms
• Polymer tip prevents clogging and initiates reliable expansion
• 50-round boxes packed in protective foam inserts
• Manufactured in Italy under ISO 9001 quality standards

Range testing demonstrates consistent 1.5-inch groups at 25 yards from the FN Five-seveN pistol. The lightweight projectile maintains flat trajectory out to 100 yards, making it effective for precision shooting applications. Law enforcement agencies report reliable feeding and extraction across multiple 5.7x28mm platforms. The tipped design performs consistently through barriers including heavy clothing and automotive glass.
