The Federal American Eagle 5.7x28mm ammunition is Pakistan’s most reliable range-grade load for FN Five-seveN and PS90 platforms now Available at Haider Arms, offering consistent performance at competitive prices. This 40gr full metal jacket (FMJ) load delivers the signature low-recoil, high-velocity performance that made the 5.7x28mm cartridge famous, with a muzzle velocity of 2,050 fps and flat trajectory ideal for tactical training and target shooting. Manufactured in the USA to NATO-spec tolerances, each round features sealed primers and brass cases that withstand Pakistan’s humid coastal climates and dusty northern ranges – unlike unsealed budget ammunition that risks moisture contamination. The optimized powder charge ensures reliable cycling in both pistols and carbines, while the FMJ projectile provides consistent penetration without excessive wear on polygonal rifling (common in FN barrels). Compared to European 5.7mm loads available in Pakistan, the Federal American Eagle Ammunition 5.7x28mm series offers 20% cost savings with identical ballistic performance to military SS190 rounds (minus armor-piercing capability). Extensive testing at Islamabad shooting facilities confirmed sub-2″ groups at 50 meters from PS90 carbines, with zero failures across 2,000+ rounds – a critical reliability benchmark for security professionals and tactical enthusiasts. The clean-burning propellant reduces fouling accumulation by 40% versus competitor brands, extending barrel life between cleanings – a key advantage for high-volume shooters. Pro Tip: For optimum accuracy, clean your 5.7x28mm chamber every 200 rounds to prevent carbon-lock issues common in this high-pressure cartridge.
