The main features of the Enduron series are copper fouling eliminator, insensitivity to temperature changes, ideal loading density and being environmentally friendly. IMR 4166 is the perfect burn speed for cartridges like the 308 Win/7.62mm NATO, 22-250 Remington, 257 Roberts and dozens more. Positively, a versatile, match grade propellant. 1 lb. container.

IMR 4895 - Originally a military powder featured in the .30-06, IMR 4895 is extremely versatile. 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 favourite of Match shooters. 1 lb. container.

IMR 3031 - A propellant with many uses, IMR 3031 has long been a favourite of .308 Match shooters using 168-grain match bullets. It is equally effective in small-capacity varmint cartridges from .223 Remington to .22-250 Remington, and its a great .30-30 Winchester powder. 1 lb. container.

IMR 4198 - This fast burning rifle powder gives outstanding performance in cartridges like the .222 Remington, .221 Fireball, .45-70, and .450 Marlin. Varmint shooters with small-bore cartridges love it. Proven metering and necessary elements were added to make it extremely insensitive to hot/cold temperatures. IMR 4198 is outstanding in cartridges like the 222 Remington, 444 Marlin and 7.62x39mm. 1 lb. container.

IMR 4451 - Another new Enduron extruded powder, IMR 4451, 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, many mid-range burn speed cartridges. 1 lb. container.

Loading density is perfect for magnums, nicely filling the case at maximum charges, contributing to superb uniformity and accuracy.

Shotgun & Pistol Powders

Hi-Skor 700-X - This extruded flake powder is ideally suited for shotshells in 12 and 16 gauge where clay target and light field loads are the norm. It doubles as an excellent pistol target powder for such cartridges as the .38 Special and .45 ACP and many more. 14 oz. container.

Hi-Skor 800-X - This large-grained flake powder is at its best when used in heavy field loads from 10 gauge to 28 gauge. In handgun cartridges 800-X performs superbly in cartridges like the 10mm auto and .44 Remington Magnum. Excellent velocity and uniformity translate into top accuracy. 1 lb. container

Trail Boss- This was designed specifically for low velocity lead bullets suitable for Cowboy Action shooting. It is primarily a pistol powder but has some application in rifles. It is based on a whole new technology that allows very high loading density, good flow through powder measures, stability in severe temperature variation, and, most importantly, additional safety to the handloader. 9 oz. container.

IMR 4227 - This is the Magnum Pistol Powder in the IMR lineup. If it says Magnum, IMR 4227 is the choice for true magnum velocities and performance. In rifles this powder delivers excellent velocity and accuracy in such cartridges as the .22 Hornet and .221 Fireball. 1 lb. container.

SR 4756 - This fine-grained, easy-metering propellant has long been a favourite of upland and waterfowl handloaders. Top velocities with great patterns. Like 800-X, SR 4756 performs extremely well in the big handgun cartridges. 1 lb. container.

SR 4759 - This bulky powder really shines as a reduced load propellant for rifle cartridges. Its large grain size gives good loading density for reduced loads, enhancing velocity uniformity. 1 lb. container.
