IMR® SMokeless Powders

IMR Smokeless Shotgun & Pistol Powders

 


SR 7625®

SR 7625

SR 7625 covers the wide range of shotshells from 10 gauge to 28 gauge in both target and field loadings. The versatile powder is equally useful in a large array of handgun cartridges for target, self-defense, and hunting loads.

SR 4756

SR 4756

This fine-grained, easy-metering propellant has long been a favorite of upland and waterfowl handloaders. Top velocities with great patterns are legendary. Like 800-X, SR 4756 performs extremely well in the big handgun cartridges. Always a top choice.

SR 4759

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.

IMR 4227

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.

IMR 4198

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 7.62 X 39.

IMR 3031

IMR 3031

A propellant with many uses, IMR 3031 has long been a favorite 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 it’s a great 30-30 Winchester powder.

IMR 8208 XBR

IMR 8208

IMR 8208 XBR The latest in the versatile IMR line of fine propellants, this accurate metering, super short grained extruded rifle powder was designed expressly for match, varmint, and AR sniper cartridges.  Ideally suited for cartridges like the 223 Remington/5.56mm, 308 Winchester/7.62mm NATO and the 6mm PPC, shooters will find IMR 8208 XBR totally insensitive to changes in temperature, while yielding max velocities and “tack driving” accuracy.  Clearly, the competitor’s “choice” and the Varmint Hunter’s “dream powder”.

IMR 4895

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 favorite of Match shooters.

IMR 4064®

IMR 4064

One of the most versatile propellant in the IMR line, used for 223 Remington, 22-250 Remington, 220 Swift, 6mm Remington, 243 Winchester Super Short Magnum, 308 Winchester, 338 Winchester Magnum, and the list goes on and on. Versatility with uniformity and accuracy.

IMR 4320

IMR 4320

Short granulation, easy metering, and perfect for the 223 Remington, 22-250 Remington, 250 Savage, and other medium burn rate cartridges. Long a top choice for the vintage 300 Savage cartridge as well.

IMR 4350

IMR 4350

The number one choice for the new short magnums, both Remington and Winchester versions. For magnums with light to medium bullet weights, IMR 4350 is the best choice.

IMR 4831

IMR 4831

Slightly slower in burn speed than IMR 4350, IMR 4831 gives top velocities and performance with heavier bullets in medium-sized magnums.

IMR 7828

IMR 7828

The BIG magnum powder. This slow burner gives real magnum performance to the large over-bored magnums, such as the 300 Remington Ultra Magnum, the 30-378 Weatherby Magnum, and the 7mm Remington Ultra Magnum. This powder is highly regarded by most magnum afficionados.

IMR 7828 SSC

IMR 7828 SSC

This magnum rifle powder has 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.
