Shotgun & Pistol Powders

IMR Shotgun & Pistol Powders

IMR powders maintained a competitive market position through the 1950’s in the reloading smokeless powder business. The company recognized the surge in the reloading market and produced their initial handloading guide in 1961. It was a modest effort limited to shotshell reloading. The 1960’s marked a very active reloading period with the invention of plastic shotshells and one-piece plastic wads. IMR introduced “Hi-Skor 700X” for target shotshell reloading in 1963.

IMR Shotgun & Pistol Powders

Hi-Skor 700-X

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.

TRAIL BOSS®

TRAIL BOSS

Trail Boss 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.

PB

PB

PB is great for Trap, Skeet, and Sporting Clays where heavy 1 ounce and 1-1/8 ounce loads are needed. In pistol it yields top performance in target and plinking loads for such cartridges as the 40 S&W, 45 Auto, etc. The small extruded grains deliver metering that is always super uniform.

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.

Hi-Skor 800-X

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.

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.
