ADI AR 2218

Description

AR 2218, manufactured by Australian Defense Industries (ADI), is a slow-burning propellant powder tailored for high-capacity rifle cartridges, particularly those demanding large charges. It is a single-base powder offering excellent performance in magnum caliber rifle loads such as the .338 Lapua Magnum and .50 BMG. Its granulation is designed to flow uniformly, although its large grain size may present challenges in finer metering setups, making it best suited for use with precision measure tools. AR 2218 is renowned for its stable performance across a wide temperature spectrum, ensuring consistent velocities in varying environmental conditions. When developing loads, testers have observed favorable ignition characteristics and predictable pressure curves, advantageous for achieving optimal ballistic results. Handloaders appreciate its capacity to maximize velocity while maintaining safe pressures, especially in long-range applications. The use of AR 2218 aligns well with ADI's reputation for producing consistent, high-quality propellants that are favored in competitive and long-distance shooting scenarios.
