The development of the Phantom 73 gr ELD-M 5.56 NAS3 began with an effort to push the envelope of the 75 gr ELD-M projectile. While the 75 gr offered excellent external ballistic potential, its overall length—when configured for optimal performance—exceeded standard magazine length. Although we were able to achieve strong performance, the cartridge would only feed reliably in certain magazines, making it impractical as a broadly deployable solution.
The 73 gr ELD-M represents the next best evolution. It maintains excellent aerodynamic efficiency while remaining fully compatible with standard magazine constraints. The result is a load that delivers consistent, repeatable performance without sacrificing reliability.
Engineered as a high-performance precision solution for SPR and designated marksman applications, the Phantom 73 gr ELD-M NAS3 features a sectional density of 0.208, a G1 ballistic coefficient of 0.398, and a G7 ballistic coefficient of 0.200. This balance of mass and aerodynamic efficiency supports strong velocity retention and reduced wind sensitivity compared to legacy 5.56 projectiles, improving first-round hit probability within realistic engagement envelopes.
When paired with NAS3 composite case technology, the cartridge achieves an average muzzle velocity of 3000 fps from an 18-inch barrel, delivering approximately 1401 ft-lbs of kinetic energy. The NAS3 case reduces overall cartridge weight while limiting heat transfer to the chamber, contributing to improved thermal management during sustained fire. The pressure curve is optimized for reliable function in both direct-impingement and piston-driven platforms.
The Phantom 73 gr ELD-M NAS3 represents a refined balance between ballistic performance, magazine compatibility, and system reliability—delivering flat trajectory, strong retained energy, and predictable wind behavior in a precision-focused 5.56 platform.
