Originally a military powder featured in the 30-06, IMR 4895 is extremely versatile as a medium burn speed propellant. From the 17 Remington to the 243 Winchester to the 375 H&H Magnum, accuracy and performance are excellent. In addition, it is a longtime favorite of Match shooters.

IMR 7828 SSC is a magnum rifle powder with exactly the same burn rate as standard IMR 7828 and uses the same data. However, due to the super short kernels, metering is virtually as good as a spherical powder. This allows up to 4% more powder space in the case and in many loads yields more velocity than standard 7828. Such loads are marked with an asterisk in the data to show where standard 7828 will not fit.

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 4166 is a versatile, match-grade propellant, with the fastest burn rate in the Enduron line. It is an extruded powder with a perfect burn speed for cartridges like 308 Winchester, 7.62mm NATO, 22-250 Remington or 257 Roberts, 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 Varget but charge weights are materially different.
