W231
firearm propellant
W231 is a smokeless powder manufactured by General Dynamics at the St. Marks plant in Florida. It is packaged, distributed, and marketed by Hodgdon Powder Company and marketed under the Winchester trade name. Hodgdon licensed the Winchester brand in January 2006, assuming all packaging and support responsibilities. 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. While the product label states "ball" powder, W231 is a flattened-ball powder.

Why this record matters
A short description can identify a subject without explaining its stakes. For “W231”, the useful work is to connect “firearm propellant” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Nov 4, 2025. The linked authority identifier is Q16821868. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2006.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
