Winchester Staball Match Rifle Powder 8lb - Temperature Stable

Winchester Staball Match rifle powder delivers consistent velocities and extreme spreads under 10 fps across temperature ranges from -40°F to 140°F. This double-base spherical powder uses advanced temperature-stable technology to maintain point of impact regardless of weather conditions, making it ideal for precision rifle competition and long-range shooting applications.

What Makes This Different

Unlike traditional powders that show velocity shifts of 1.5 fps per degree, Staball Match maintains consistent burn rates across extreme temperature variations. The copper-reducing additives extend barrel life by reducing copper fouling buildup, while the spherical granules meter uniformly through powder measures for consistent charge weights. Independent testing shows this powder produces standard deviations under 8 fps in match-grade rifles.

Key Features

• Temperature-stable formula maintains velocity within 10 fps from -40°F to 140°F
• Double-base spherical powder for consistent metering and ignition
• Copper-reducing additives minimize barrel fouling and extend barrel life
• Optimized for .308 Winchester, 6.5 Creedmoor, and .223 Remington match loads
• Clean-burning formula reduces residue buildup in gas systems
• 8-pound container provides approximately 1,100-1,400 match loads depending on cartridge
• Lot-to-lot consistency ensures reproducible load development results

Competitive shooters rely on Staball Match for F-Class, Precision Rifle Series, and benchrest competitions where single-digit extreme spreads determine match outcomes. The powder's consistent burn rate eliminates the need for seasonal load adjustments, maintaining zero shifts under 0.25 MOA across temperature extremes. Long-range hunters benefit from predictable trajectories whether hunting in sub-zero conditions or desert heat.
