Hodgdon H4198 Extreme Smokeless Rifle Powder 1 lb Container

The Hodgdon H4198 Extreme Smokeless Rifle Powder delivers consistent performance across extreme temperature variations, making it ideal for precision shooting and hunting applications. This fast-burning powder excels in small to medium cartridges where accuracy and velocity consistency matter most. Temperature-stable formulation maintains ballistic performance from -40°F to 140°F.

What Makes This Different

Extreme series powders feature temperature-insensitive formulation that eliminates velocity shifts common with standard powders. While conventional powders can vary 1.5-2 fps per degree of temperature change, H4198 Extreme maintains velocity within 0.5 fps per degree. This stability translates directly to consistent point of impact regardless of weather conditions. The copper-reducing additive also extends barrel life compared to standard formulations.

Key Features

• Temperature-stable formulation maintains consistent velocities from -40°F to 140°F
• Fast burn rate optimized for .222 Remington, .223 Remington, and similar small capacity cases
• Copper-reducing additive minimizes barrel fouling and extends cleaning intervals
• Spherical powder design meters consistently through powder measures
• 1-pound sealed canister with moisture-resistant packaging
• Lot-to-lot consistency ensures reliable load development results
• Clean-burning formulation reduces residue buildup in action and barrel

Competitive shooters rely on H4198 Extreme for match-grade ammunition in varmint cartridges and light bullet applications. The powder's consistent metering characteristics make it suitable for both progressive and single-stage reloading setups. Hunters appreciate the temperature stability when transitioning from warm-weather load development to cold-weather hunting conditions. The clean-burning properties reduce maintenance requirements during extended shooting sessions.
