IMR was originally and has always been a large supplier of powder for the military. IMR stands for Improved Military Rifle!
Just about every powder manufacturer has bulk grade powders and cannister grade powder. The cannister is made to sell at retail and is much, much more consistant than bulk grade. The bulk grade is sold to ammunition manufacturers, including military contractors, and each lot is tested and loads adjusted because of the amount of variation lot to lot.
