- IMR 4166 – is the first in the series of Enduron propellants. It’s a perfect burn speed for cartridges like the 308 Win/7.62mm NATO, 22-250 Remington, 257 Roberts and dozens more. IMR 4166 is a positively versatile, match grade propellant.
- IMR 4451 – Another new Enduron powder that gives top performance in the venerable 30-06, 270 Winchester and 300 Winchester Short Magnum, to name just a few. This propellant is ideally suited for many mid-range burn speed cartridges.
- IMR 7977 – is the slowest burn rate Enduron Technology powder. It is a true magnum cartridge propellant with outstanding performance in such cartridges as the 300 Winchester Magnum, 7mm Remington Magnum, 338 Lapua and more.
