Hodgdon H4831SC Extreme Rifle Powder 1lb - Multi-Caliber

The Hodgdon H4831SC Extreme rifle powder delivers consistent performance across multiple magnum calibers with temperature-stable formulation. This short-cut extruded powder meters more uniformly than standard H4831, reducing charge weight variations by up to 50%.

What Makes This Different

H4831SC features Hodgdon's Extreme powder technology with copper fouling eliminator and flash suppressant additives. The short-cut kernels flow through powder measures 40% more consistently than long-grain alternatives. Temperature sensitivity remains within ±1 fps per degree Fahrenheit across hunting temperature ranges from -40°F to 140°F.

Key Features

• Temperature-stable Extreme formulation maintains velocity consistency
• Short-cut extruded kernels for improved metering accuracy
• Copper fouling eliminator reduces barrel cleaning frequency
• Flash suppressant minimizes muzzle signature
• Optimized for .270 Winchester, .280 Remington, 7mm Remington Magnum
• Excellent performance in .300 Winchester Magnum and .338 Winchester Magnum
• 1-pound canister provides approximately 140-175 cartridge loads

Field testing demonstrates H4831SC maintains sub-MOA accuracy potential in precision rifles while delivering hunting-weight bullet velocities. The powder performs consistently in both competition and hunting applications, with minimal velocity spread across temperature extremes. Hunters report reliable ignition and consistent point of impact from early morning cold to midday heat.
