Ya know what, I almost don't want to post in this thread.
Look, if you buy a powder today, and the manufacturer says: "They are exactly the same powder" why do folks try to drum up differences?
Should you buy a can of W231 right now and have a can from 10 years ago, what do you think will be the difference? Minimal at best BUT there can be whatever tolerances are allowed to a batch of powder there.
HP-38 and W231, are the same powder, um, period. If there is any difference found between the two, it is simply because of tolerances in batches.
One reason folks like one powder over another, even though they are the same, can be found in doing a little research on what has gone by the wayside while it's counterpart is still on the market.
People are just people that have preferences. Maybe it is the nice blue on the label. I bet that is it. W231's blue label is secretly emitting a subliminal message, put there by the goobermint all the while it is secretly a completely different powder!
