Description ADI’s AR2207 powder is a very useful fine-grained and fast burning rifle powder designed for many popular rifle cartridges. ADI Powders cater for the full range of burning rate requirements from the fast burning handgun and shotgun powders to the very slow large calibre rifle powders. The rifle powders are single perforated tubular propellants of single base composition. ADI’s experience in developing powders for the Australian Defence Force has shown that powders with these characteristics are suitable for use in extreme climatic conditions. Consequently, all the rifle powders have, as a feature, ballistic temperature independence; that is, velocities and pressures do not vary greatly with ambient temperature. This is a unique and major advantage over the performance of other manufacturer’s rifle powders. In addition, the ADI powders all have good loading characteristics with respect to bulk density and uniformity of metering through powder loaders. They are also very clean burning at normal loads.
