Winchester 231 Ball Powder 4lb Container - Pistol Reloading Powder

Winchester 231 Ball Powder delivers consistent performance for pistol cartridge reloading with its double-base spherical propellant formula. This 4-pound container provides enough powder for approximately 1,750-2,000 rounds depending on cartridge and load specifications. The clean-burning composition reduces fouling buildup while maintaining reliable ignition across temperature ranges.

What Makes This Different

Winchester 231 uses a spherical ball powder design that meters more consistently through progressive press powder measures compared to flake powders. The double-base formulation burns cleaner than many single-base alternatives, reducing barrel fouling and extending cleaning intervals. Temperature stability remains consistent from 0°F to 125°F, making it suitable for year-round loading and storage.
