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!” 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.
