Remington UMC 223 Rem 55-grain lead-free ammunition delivers clean, reliable performance for shooters who demand both safety and accuracy at the range. Engineered for law enforcement training, military qualification, and civilian sport shooters, this 20-round-per-box load eliminates lead exposure at the firing line while maintaining the velocity and consistency UMC is known for. The re-engineered formulation pairs proven Remington engineering with modern environmental and health standards, making it an ideal choice for indoor ranges, outdoor precision work, and high-volume training scenarios.
The Rem UMC 223rem 55gr Leadfree round features copper-jacketed compressed-core projectiles that deliver consistent ballistics while reducing splash-back and fouling on steel targets. Remington's Catalyst clean priming technology eliminates traditional lead primers, significantly reducing airborne particulate exposure—a critical consideration for indoor range facilities and high-frequency shooters. At 55 grains, this projectile weight is optimized for AR-15 platforms and other standard 223 Remington rifles, offering a flat trajectory suitable for target work from 25 to 200+ yards. The non-lead construction does not compromise velocity, accuracy, or reliability compared to traditional UMC loads.
Law enforcement academies, military training ranges, and civilian shooting clubs benefit most from this ammunition's combination of clean priming, reduced environmental impact, and cost-effective pricing. The 223 Rem cartridge is fully compatible with all standard AR-15 platforms, bolt-action rifles, and semi-automatic sporting rifles chambered in 223 Remington or 5.56 NATO (though 5.56 NATO rifles may exhibit slightly increased velocities). Each box contains 20 rounds, making it practical for qualification shoots, skills validation, and high-volume range sessions where lead exposure must be minimized without sacrificing performance or budget efficiency.
