Winchester StaBall HD is a temperature-insensitive Ball Powder that remains stable in extreme hot or cold temperatures. This slow-burning magnum powder delivers optimal loading density in big capacity magnum cartridges suitable for the burn speed, making it ideal for 6.5 PRC, 7mm Remington Mag, 300 PRC, and many more calibers.

Precision metering, typical of a ball powder, helps to better velocity and pressure standard deviations, all of which are critical to match grade accuracy! This “green” propellant contains copper fouling reducer additives, allowing for extended periods of competition and field shooting without the need to clean the bore.

Throughout the game, you must maintain pinpoint precision! Depending on the cartridge, the achievable velocity levels are 75-100 fps higher than other propellants in its class. As a result, the StaBALL family offers Stability, Precision, and Speed.

Other Important Information:
