Product Overview and Introduction

Achieve peak velocity, consistent pressure curves, and exceptional accuracy across a wide range of heavy-hitting magnum handgun calibers and specialty rifle cartridges with IMR 4227 Smokeless Powder (1 lb). As a fast-burning extruded (stick) propellant, IMR 4227 is uniquely versatile, serving as a legendary favorite for high-pressure revolver cartridges as well as small-to-medium capacity rifle cases and Hornet variants.

Whether you are handloading maximum-velocity hunting loads for the .44 Magnum, crafting precision target rounds for the .357 Magnum, developing heavy loads for the .500 S&W, or reloading small-capacity rifle cartridges like the .22 Hornet and .218 Bee, IMR 4227 delivers the clean-burning performance and precise ignition required by demanding reloaders.

Fast-Burning Efficiency and Extruded Consistency

Engineered to meet strict chemical and physical manufacturing standards, IMR 4227 offers distinct advantages on the reloading bench:

• Fast Burning Rate: Tailored specifically to generate high velocities in large-capacity handgun cases and smaller rifle chambers without excessive peak pressure.

• Extruded Stick Uniformity: Precision-cut grains meter smoothly through powder measures and drop tubes, ensuring consistent charge weights and low standard deviations.

• Clean-Burning Formulation: Designed to minimize unburned powder residue and barrel fouling, keeping your revolver cylinders and rifle bores cleaner during extended shooting sessions.

• Versatile Cross-Platform Application: Equally at home powering heavy magnum revolvers, lever-action pistol-caliber carbines, and specialty benchrest rifle loads.
