Fiocchi 57JF35 5.7x28mm 35gr Jacketed Frangible Ammo 50rd Box

The Fiocchi 57JF35 Hyperformance delivers specialized frangible performance for 5.7x28mm platforms requiring reduced ricochet risk. This 35-grain jacketed frangible ammunition breaks apart upon impact with hard surfaces while maintaining terminal effectiveness on soft targets. Professional training facilities and law enforcement agencies choose this load for close-quarters scenarios where overpenetration concerns demand controlled fragmentation.

What Makes This Different

Unlike traditional FMJ rounds that maintain structural integrity through barriers, the 57JF35 features a compressed metal powder core designed to disintegrate upon striking hard surfaces at velocities above 2,000 fps. The jacketed construction ensures reliable feeding and ejection in semi-automatic firearms while the frangible core reduces ricochet potential by up to 96% compared to solid projectiles. This engineered fragmentation occurs only on impact with surfaces harder than the bullet itself, preserving effectiveness against soft tissue targets.

Key Features

• 35-grain jacketed frangible projectile with compressed metal powder core
• Reduced ricochet risk for close-quarters training and tactical applications
• Muzzle velocity of approximately 2,350 fps from 4.7-inch barrel
• Consistent feeding in FN Five-seveN, P90, and PS90 platforms
• Non-toxic composition suitable for indoor range use
• Boxer-primed brass cases for potential reloading
• 50-round boxes packed 10 per case (500 total rounds)

Range performance demonstrates reliable cycling across 5.7x28mm platforms with minimal fouling compared to lead-core alternatives. The frangible design makes this ammunition particularly valuable for shoot house training, aircraft security applications, and urban environments where bullet fragmentation reduces collateral damage risks. Accuracy remains consistent within 2-3 MOA at 25 yards from quality barrels, meeting training requirements while providing the safety benefits of controlled fragmentation.
