I agree with Mal H regarding Hodgdon's naming of three distinct powders using the word "Clays" in each. I think that this may eventually contribute to an accident through simple failure of communication.
I strongly recommend listing the ADI numbers along with Hodgdon's names:
Clays= AS30N
International Clays= AS50N
Universal Clays= AS70N and/or AP70N
