IMR has released a series of five popular burn-rate powders covers an extremely wide range of shotshell and pistol cartridges—utilizing new green technology. Each powder was designed to match current shotshell bushing charts, so handloaders will already have the appropriate bushings available for each load. According to IMR, this new technology "burns clean, providing accurate metering and top performance characteristics." Additionally, all of these powders are REACH compliant, meaning they are not harmful to the environment.
IMR Target The first powder in this new family is a fast-burning pistol powder. This fine-grained, small-flake pistol powder meters superbly, providing very precise loads in even small pistol cartridges like the .25 ACP
IMR Red The second powder in this new family was designed to be an efficient, clean-burning, 12-gauge target powder. IMR Red also good for match competition loads and Cowboy reduced loads.
IMR Green The third in this new family is slightly slower-burning than IMR Red, making it an ideal trap handicap powder and also for sporting Clays enthusiasts.
IMR Unequal IMR Unequal combines small-sized flakes for uniform metering in all pistol applications and its burn speed accommodates a wide range of shotshell and pistol cartridges.
IMR Blue The slowest burn speed of the five new propellants, IMR Blue for heavy 12-gauge 2-¾-inch, 3-inch and 3-1/2-inch field loads.
These new powders will be available in January 2017. Complete load data is accessible on the Hodgdon Reloading Data Center at HodgdonReloading.com.
