Winchester StaBALL Match is a temperature-insensitive, double-base, BALL Powder, stable in extreme-hot or -cold conditions. This powder provides optimal loading density in cartridges appropriate for the burn speed, which is ideal for high-BC heavy for caliber bullets in 223 Remington, 224 Valkyrie, 22-250 Remington, 308 Winchester, 30-06 and many more.  This REACH-compliant, “environmentally green” propellant has copper fouling reducer additives, which contribute to shooting sessions without cleaning the bore. Velocity levels obtainable, depending on the cartridge, are 50-75fps greater than other propellants in its class. Thus, the StaBALL family provides Stability, Precision and Speed.
