The Phantom 75 gr ELD-M 5.56 NAS3 cartridge is engineered as a high-performance precision load for SPR and designated marksman applications where external ballistic efficiency, terminal consistency, and system optimization are critical. Featuring a sectional density of 0.214, a G1 ballistic coefficient of 0.467, and a G7 ballistic coefficient of 0.235, the 75-grain ELD-M projectile provides excellent velocity retention and reduced wind sensitivity compared to legacy 5.56 projectiles, improving first-round hit probability at extended distances.
When paired with a NAS3 composite case, the cartridge achieves an average muzzle velocity of 2,900 fps from an 18-inch barrel and delivers approximately 1,401 ft-lbs of kinetic energy, while reducing overall cartridge mass and limiting heat transfer to the chamber. The resulting pressure curve is optimized for reliable function in both direct-impingement and piston-driven platforms, supporting sustained fire with improved thermal characteristics. Designed around modern SPR engagement envelopes, the Phantom 75 gr ELD-M NAS3 combines flat trajectory, high retained energy, and predictable wind performance into a next-generation precision 5.56 solution.
