Winchester StaBall 6.5 Smokeless Gun Powder

Winchester StaBall 6.5 is the world’s first temperature-insensitive Ball Powder, stable in extreme-hot or -cold conditions.  It provides optimal loading density in cartridges appropriate for the burn speed, which is ideal for 6 Creedmoor, 6GT, 6.5 Creedmoor, 7MM-08, 270 Winchester and many more.

Typical of a ball powder, precise metering contributes to improved velocity and pressure standard deviations, ingredients that are paramount to match grade accuracy! This “environmentally green” propellant has copper fouling reducer additives, meaning longer durations of competition and field shooting without having to clean the bore.

Precision accuracy throughout the match! Velocity levels obtainable, depending on the cartridge, are 30-200 fps greater than other propellants in its class. Stability, Precision and Speed, says Winchester StaBALL 6.5 is the “Best of the Best!”

Precision-Tuned for 6.5-Caliber Accuracy

Winchester StaBall 6.5 was formulated with the precision shooter in mind especially those loading for 6.5 Creedmoor, 6.5 PRC, and similar 6.5mm cartridges. If you chase tighter groups, lower extreme spread, and a more predictable trajectory at long range, StaBall 6.5 gives you a consistent burn profile that helps reduce shot-to-shot variance. It’s the powder to reach for when you want repeatable ballistics during match day, sight-in sessions, or critical hunting shots.

Temperature-Insensitive Performance Shoot Confidently in Any Climate

One of StaBall’s standout benefits is its temperature stability. StaBall 6.5 maintains consistent pressures and velocities across a wide range of real-world conditions, so your zero and dope remain trustworthy whether you’re testing loads on a cold morning or competing in summer heat. That stability removes one more variable from long-range shooting and helps you focus on wind calls and fundamentals not worrying about the weather.

Clean-Burning, Smooth Metering for Efficient Reloading

StaBall 6.5 features fine, spherical grains that meter consistently through measures and dispensers, making both single-stage and progressive press work fast and predictable. Its clean-burning chemistry reduces copper and carbon fouling, meaning barrels hold accuracy longer during strings and maintenance becomes less frequent. The net result: quicker load development, less downtime cleaning, and more time on target.

Why Serious Reloaders Choose StaBall 6.5

• Optimized for 6.5 Creedmoor, 6.5 PRC and similar precision cartridges.

• Temperature-insensitive formula for consistent velocities.

• Fine spherical grains for excellent metering and fast reloading.

• Clean-burning to reduce fouling and sustain accuracy during long strings.

• Great for match shooters, long-range hunters, and precision handloaders.

Other Important Information:

• Do not exceed the loads displayed in the reloaders guide.
• Never mix any two powders regardless of type, brand, or source.
• Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
