Winchester STABALL 1 Rifle Powder 1lb - Temperature Stable

Winchester STABALL 1 Rifle Powder delivers consistent performance across extreme temperature variations, making it ideal for precision shooters who demand reliable velocities in changing conditions. This temperature-stable propellant maintains velocity consistency from sub-zero to desert heat, eliminating the need for load adjustments based on weather conditions.

What Makes This Different

STABALL 1 utilizes Winchester's advanced temperature-stable formulation that reduces velocity variation to less than 1 fps per degree Fahrenheit. Unlike traditional powders that can show 50+ fps velocity swings in temperature extremes, this propellant maintains consistent burn rates from -40°F to 125°F. The spherical grain structure meters exceptionally well through progressive presses, providing charge weight consistency within 0.1 grains for match-grade ammunition.

Key Features

• Temperature-stable formulation reduces velocity variation to <1 fps per °F
• Spherical grain structure for precise metering in all powder measures
• Optimized for .223 Remington, .308 Winchester, and 6.5 Creedmoor cartridges
• Low muzzle flash and minimal fouling for extended shooting sessions
• 1-pound container provides approximately 140-200 rounds depending on charge weight
• Copper crusher tested pressure ratings ensure safe maximum loads
• Consistent burn rate across temperature extremes from -40°F to 125°F

Precision rifle competitors rely on STABALL 1 for its ability to maintain point of impact regardless of match conditions. The powder's stable burn characteristics translate to consistent group sizes whether shooting early morning cold bore shots or rapid-fire stages in summer heat. Law enforcement and military users benefit from the reduced need to re-zero rifles when deploying across different climate zones.
