FN 5.7x28mm 40gr FMJ Ammunition - 50 Round Box (10700032)

The FN 10700032 delivers consistent terminal performance in the specialized 5.7x28mm cartridge, engineered specifically for FN Five-seveN pistols and PS90 carbines. This full metal jacket ammunition provides reliable feeding and extraction across FN's 5.7x28mm platform while maintaining the cartridge's signature flat trajectory and minimal recoil characteristics.

What Makes This Different

FN's factory ammunition represents the gold standard for 5.7x28mm performance, manufactured to the exact specifications that define this unique cartridge. Unlike third-party loads that may compromise on powder selection or bullet construction, FN ammunition maintains strict quality control standards that ensure optimal pressure curves and velocity consistency. The 40-grain FMJ bullet achieves approximately 2,350 fps from a Five-seveN pistol barrel, delivering energy levels that exceed most traditional pistol cartridges while producing significantly less felt recoil.

Key Features

• 40-grain full metal jacket bullet optimized for 5.7x28mm chamber dimensions
• Factory-loaded by FN using proprietary powder formulations
• Brass cases manufactured to withstand high-pressure loadings (up to 50,000 PSI)
• Consistent muzzle velocity of 2,350 fps from 4.8-inch barrel
• Low recoil impulse enables rapid follow-up shots
• 50-round packaging reduces per-round cost for training applications
• Compatible with all 5.7x28mm firearms including Five-seveN and PS90

The 5.7x28mm cartridge excels in applications requiring penetration capabilities combined with manageable recoil characteristics. Law enforcement agencies appreciate the round's ability to defeat soft body armor while maintaining accuracy at extended pistol ranges. Competition shooters benefit from the flat trajectory that simplifies holdover calculations beyond 50 yards. The lightweight bullet construction minimizes over-penetration concerns in defensive scenarios while still delivering adequate terminal performance on target.
