IMR 4895 Smokeless Gun Powder

Clear Product Overview

IMR 4895 Smokeless Gun Powder is a legendary, versatile medium-burn extruded rifle propellant. Originally developed as the official military powder for the .30-06 Springfield during World War II, IMR Powder Company designed it to serve as a foundational, highly adaptable propellant for standard rifle calibers.

First, IMR 4895 holds an iconic status among military surplus firearms enthusiasts, specifically as the gold standard propellant for reloading M1 Garand ammunition. Consequently, its burn rate generates the exact port pressure necessary to safely cycle gas-operated military rifles without bending operating rods. As a result, it is a top choice for target marksmen and hunters reloading .30-06 Springfield, .308 Winchester, .223 Remington, .243 Winchester, and .300 Savage. Furthermore, its cylindrical stick grain structure ensures consistent combustion and velocity stability. Therefore, it delivers match-winning precision, predictable trajectory performance, and wide multi-caliber utility.
