....that they package the two brand only due to 'brand loyalty'. Meaning half of the people said HP-38 is superior in every way and the other half said that W231 is the best and they wouldn't touch junk like HP 38.
Well, when your reach out to Hodgdon with the question, they emphatically state that HP-38 and W231 are the exact same powders, that they come off of the same manufacturing line and packaged for Hodgdon and Winchester.
