Winchester Staball HD Rifle Powder 1lb - Temperature Stable Propellant

Winchester Staball HD rifle powder delivers consistent velocities across extreme temperature ranges, making it ideal for precision shooters who demand reliable performance. This temperature-stable propellant maintains velocity consistency from -40°F to 140°F, eliminating the need for load adjustments based on weather conditions.

What Makes This Different

Staball HD utilizes Winchester's copper-fouling reducer additive technology, significantly reducing barrel cleaning frequency compared to traditional powders. The spherical grain structure provides excellent metering characteristics through powder measures, delivering charge-to-charge consistency that translates directly to improved accuracy. Independent testing shows velocity standard deviations under 10 fps when properly loaded.

Key Features

• Temperature stable formula maintains consistent velocities from -40°F to 140°F
• Copper-fouling reducer additive extends barrel life and reduces cleaning frequency
• Spherical grain structure ensures precise metering in powder measures
• Optimized for cartridges from .223 Remington through .300 Winchester Magnum
• 1-pound container provides approximately 140-200 loads depending on cartridge
• Low flash signature reduces muzzle flash in low-light conditions
• Consistent burn rate across temperature extremes eliminates seasonal load adjustments

Field testing demonstrates Staball HD's versatility across multiple shooting disciplines, from precision rifle competition to long-range hunting applications. The powder's temperature stability proves particularly valuable for hunters traveling between different climate zones or competitive shooters facing varying match conditions. Reduced copper fouling means shooters can fire 200+ rounds before accuracy degradation becomes measurable.
