Is HP-38 really the samed as W231?

Is it just that Hogdson uses the same formula or are these two accidentally the same?

Or they are not really the same but people realized that the same charges worked no matter which of the two was used?

Many years ago the difference was in the absorbent material used. If I remember correctly HP-38 used cotton fibers as a base and 231 used wood cellulose. Now they are the same and come from St. Marks.

Except for perhaps a few black powder substitutes, Hodgdon doesn't manufacture any of their powders. They have merchandising rights, and agreements, but all powders are manufactured by third parties. I believe Alliant is the only manufacturer that markets their own products (except for the Reloder series). We do have domestic powder manufacturers, but they don't seem to sell direct to the wholesale chain like they once did, but rather to marketers like Hodgdon & Western. I'm sure I'm missing a manufacturer here, but can't think of them at the moment. Even IMR is distributed but Hodgdons now.
