Winchester Powder StaBALL 6.5 Smokeless Rifle Powder 8 lb

The Winchester StaBALL 6.5 is a premium temperature-insensitive, double-base Ball Powder engineered specifically for high-velocity rifle reloading. Hailed as the world's first temperature-stable ball powder, StaBALL 6.5 delivers consistent performance in both extreme-hot and extreme-cold conditions, making it a top choice for match shooters and serious handloaders who demand predictable velocities and pressures regardless of ambient temperature. Its precise metering produces tight velocity and pressure standard deviations shot after shot, and the formulation is also noted for reduced copper fouling during extended range sessions.

This 8 lb container is optimized for popular bottleneck rifle cartridges including the 6.5 Creedmoor, 6 Creedmoor, 270 Winchester, and 7mm-08, among others. Published load data shows StaBALL 6.5 delivering 30-200 fps gains over comparable competitive powders in select rifle applications. The double-base chemistry, paired with the ball powder kernel geometry, gives handloaders excellent metering through progressive presses for both precision and high-volume workflows.

Sold as a single 8 lb canister of smokeless propellant. Like all reloading powders, StaBALL 6.5 is classified as hazardous materials and ships under applicable HAZMAT regulations by both air and ground carriers. Always consult the most current published load data from the manufacturer and start at recommended starting charges when developing any new load.
