Product Overview and Introduction

Push heavy big-game bullets to maximum muzzle velocities and achieve exceptional long-range accuracy across massive ultra-magnum calibers with IMR 7828 Smokeless Powder. As one of the slowest-burning extruded (stick) propellants in the IMR lineup, IMR 7828 was specifically formulated to deliver unmatched performance in large-capacity magnum rifle cases where heavy projectile weights require slow, sustained pressure curves.

Whether you are handloading long-range hunting ammunition for the .300 Weatherby Magnum, crafting flat-shooting rounds for the 7mm Remington Magnum and .300 Win Mag, or developing performance loads for ultra-magnum cartridges like the .338 Lapua and 26 Nosler, IMR 7828 provides the stellar velocity and kinetic energy required by precision long-range marksmen.

Ultra-Slow Burning Efficiency and Precision Extruded Quality

Engineered to exacting chemical and physical manufacturing standards, IMR 7828 offers distinct advantages on the reloading bench:

• Ultra-Slow Burning Rate: Tailored exclusively for large-capacity magnum and ultra-magnum cases, ensuring complete and efficient combustion under high projectile mass.

• Extruded Stick Uniformity: Precision-cut grains meter smoothly through volumetric powder measures and drop tubes, minimizing charge weight variance for consistent velocity spreads.

• Maximum Downrange Energy: Designed to extract the highest possible velocities from big-bore and magnum cartridges without inducing destructive pressure spikes.

• Clean-Burning Formulation: Engineered to minimize residue buildup and barrel fouling, preserving accuracy over extended shooting strings in the field or at the range.

The Professional Choice for Heavy Magnum Rifle Reloading

When your reloading bench requires a specialized, ultra-slow burning propellant to drive heavy-caliber magnum rifles to peak velocity and match-grade precision, IMR 7828 Smokeless Powder stands out as a premier heavy-duty component for your powder locker.
