W231
From Wikipedia, the free encyclopedia
W231 is a smokeless powder manufactured by the Hodgdon Powder Company and marketed under the Winchester trade name. Hodgdon licensed the Winchester brand in January 2006, assuming all manufacturing and support responsibilities.[1] Prior to this Winchester brand powders were manufactured by the Olin Corporation.
W231 is commonly used in metallic cartridge reloading and handloading. It is used primarily for pistol cartridges. Because of the spherical shape of the powder grains, W231 is classified a ball powder, as opposed to a stick or flake powder.
