In the world of precision shooting and hunting, consistency is king. The IMR 4955 powder stands as a testament to this principle, offering shooters a versatile, match-grade propellant that fills an essential niche in cartridge loading. Positioned strategically between IMR 4451 and IMR 7977 in terms of burn speed, this extruded powder delivers exceptional performance for big game cartridges like the .25-06 Remington, .270 Winchester, .280 Remington, and the formidable .300 Winchester Magnum.
The defining characteristics of IMR 4955 include its insensitivity to temperature variations—a crucial factor when your mission depends on reliability across diverse climates. This powder also boasts an ideal loading density which ensures optimal pressure levels within your firearm's chamber.
A standout feature is its copper fouling eliminator capability. Over time, copper deposits from bullet jackets can degrade accuracy; however, with IMR 4955’s formulation minimizing such build-up, you maintain peak performance shot after shot. Additionally—and importantly—this product maintains environmental responsibility without sacrificing quality or efficacy.
Packaged conveniently in a one-pound canister for ease of transport and storage at home or in the field—the Enduron® line continues to embody innovation with each iteration it introduces into our ballistic repertoire. Whether you're reloading for small calibers like the .223 Remington or venturing into larger territories such as the massive .500 Nitro Express Magnum—IMR 4955 proves itself indispensable among discerning marksmen seeking unfaltering excellence.
