If there is one parameter that most reloaders like to vary in their reloads it is the propellant. Some propellants have burning rates that make them suitable for use in small pistol calibers, whereas others are suitable for use in large magnum rifle rounds.
Known as Red, Blue, Green, Target and Unequal, the new powders from IMR are intended for shotgun and handgun loading. The new IMR family of powders burns green, clean and more efficiently. IMR Target is advertised as suitable for .25 ACP, .32 S&W Long, .38 Special, .44 Special and .45 ACP. IMR Blue and Green are shotgun powders. Unequal is listed for shotguns, as well as handguns ranging from .32 ACP to .44 Magnum—including 9mm Luger, .40 S&W and .45 ACP. IMR Red is listed as suitable for use in .38 Special, .44 Special, .45 Auto, .45 Colt and 12-gauge shotgun. This new series of powders covers a lot of possibilities for reloaders.
