Here is a press release regarding their new powders:

IMR Legendary Powders is excited to announce a new family of shotshell and pistol propellants.
We believe it takes a Legendary Powder brand like IMR to improve this series of legendary powders. This 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 the handloader will already have the appropriate bushings available for each load. This new technology burns clean, providing accurate metering and top performance characteristics. All of these powders are REACH compliant, meaning these propellants 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 the smallest 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 performs nicely in various lead pistol target loads, such as 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 soon a favorite with 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, has excellent application for heavy 12-gauge 2-¾-inch, 3-inch and 3-1/2-inch field loads."
Interesting to note:
IMR Target similar in burn rate to Bullseye
IMR Red similar in burn rate to Red Dot
IMR Green similar in burn rate to Green Dot
IMR Unequal similar in burn rate to Unique
IMR Blue similar in burn rate to Blue Dot
It appears they are trying to cash in on the popularity of the associated Alliant Powders. There are some differences such as their green claims. What is most interesting is their clean burning claims. If their Unequal product is close enough in burn rate and much cleaner burning than Unique then they might have a good competitive product.
