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 Enduron 4955 is a versatile, match-grade propellant with a mid-range burn speed that is in between IMR4451 and IMR7977. It is an extruded powder and provides top performance for big game cartridges like 25-06, 270 Winchester, 280 Remington and 300 Win Mag, among other cartridges.

The main features of the Enduron series are copper fouling eliminator, insensitivity to temperature changes, ideal loading density and being environmentally friendly.

This propellant performs comparably to Hodgdon H4831 but charge weights are materially different.

IMR recommends always consulting www.IMRReloading.com for the most accurate, up-to-date data.

Available in 1-LB and 8-LB containers.

IMR Enduron 7977 is a slower burn rate in the Enduron family. Loading density is perfect for magnums, contributing to superb uniformity. This is a true magnum propellant yielding outstanding performance in 300 Winchester Magnum, 7mm Remington Magnum and 338 Lapua, among other cartridges. Loading density is perfect for magnums, nicely filling the case at maximum charges, contributing to superb uniformity and accuracy.

The main features of the Enduron series are copper fouling eliminator, insensitivity to temperature changes, ideal loading density and being environmentally friendly.

IMR 7977 performs comparably to Hodgdon H1000 but charge weights are materially different.

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.

IMR Red is a 12-gauge target powder for light 7/8- to 1-1/8- oz. Handicap trap loads. Will produce efficient low charge weights, mild muzzle report and minimal recoil. Great for dove and light field 12- gauge loads! Performs well in various lead pistol target loads, such as match competition loads and cowboy action reduced loads.

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 most accurate, up-to-date data and bushing charts.

IMR Target 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.

IMR Target is a fast-burning pistol powder yielding outstanding performance in 25 ACP, 38 Special and 45 ACP. It’s perfect for cowboy action target loads, where reduced recoil loads are needed.
