Winchester STABALL 8 Rifle Powder 8lb Container - Temperature Stable

Winchester STABALL 8 rifle powder delivers consistent velocities across extreme temperature ranges, making it ideal for precision shooters who demand reliable performance. This temperature-stable propellant maintains velocity consistency from -40°F to 140°F, eliminating the guesswork in load development for varying conditions.

What Makes This Different

STABALL 8 utilizes Winchester's proprietary temperature-stable technology that reduces velocity variation by up to 50% compared to conventional powders. The spherical powder design meters consistently through progressive presses and powder measures, while the copper-reducing additive extends barrel life. Load data shows exceptional accuracy potential with match bullets in cartridges from .223 Remington through .300 Winchester Magnum.

Key Features

• Temperature-stable formula maintains consistent velocities from -40°F to 140°F
• Spherical powder design ensures precise metering through all powder measures
• Copper-reducing additive extends barrel life and reduces fouling
• Optimized for cartridges from .223 Remington to .300 Winchester Magnum
• Low flash signature reduces muzzle flash for tactical applications
• Consistent lot-to-lot performance eliminates load re-development
• 8-pound container provides approximately 1,000+ rounds of .308 Winchester loads

Field testing demonstrates STABALL 8's ability to maintain point of impact across seasonal temperature swings that would shift other powders by several inches at 300 yards. Competition shooters report consistent chronograph readings throughout match days, while hunters appreciate knowing their zero remains true from early season heat to late season cold. The powder's clean-burning characteristics reduce cleaning frequency and maintain accuracy over extended shooting sessions.
