IMR 4166 1lb
IMR Legendary Powders, based in Shawnee, Kansas, has developed a line of advanced extruded powders based on Enduron Technology. Their fine, extruded propellant has a copper fouling eliminator, is temperature insensitive, has an optimum loading density, and is environmentally benign.
Enduron propellant IMR 4166 is the first in a line of Enduron propellants. It's the ideal burn speed for cartridges such as the 308 Win/7.62mm NATO, 22-250 Remington, 257 Roberts, and a slew of others. Definitely a match-grade propellant with a lot of versatility.
