IMR Blue™ (Copy)

This product has been discontinued.

IMR Blue is one of a new IMR family of powders that have comparable burn speeds to competitor powders. This new IMR family uses new, modern technology to ensure the product is “green,” burns clean and, in most cases, results in more energy from each grain of powder. IMR powders are consistent in bulk densities from lot to lot, eliminating some of the variability inherent in other competitors.

With the slowest burn speed of the new IMR family, IMR Blue is a true magnum propellant yielding outstanding performance in 12-gauge shotshells. Ideal burn speed for ”back fence games” where 1-1⁄4- and 1-3/8-oz. loads are the norm. Data for 10-gauge, 16-gauge and 20- gauge also available, providing true magnum velocities and performance.

For shotshell usage, powder densities are similar to competitor data. Most shotshell data is similar, but IMR recommends always consulting www.IMRReloading.com for the correct, up-to-date data and bushing charts. For pistol usage, pistol data is materially different from competitor data with lower charge weights and higher velocities at maximum pressures. IMR recommends always consulting www.IMRReloading.com for the correct, up-to-date data.
