I don't think Hodgdon could have made it more confusing. I read about guys favoring "Clays" for the .45 and since I've never used it, I decided to go to my trusty #9 Speer manual and compare to the #14 manual. The #9 doesn't list any sort of Clays for any weight bullet. Matter of fact, they don't even have data for the 185 gr JHP or 230 FMJ. So, I checked in the #14 manual and the only "Clays" listed is U.Clays which I assume to be Universal Clays. Hodgdon's website shows three different powders with the name "Clays" in it. Clays, Universal Clays and International Clays although only two that they really specify for the .45 is either Clays or Universal Clays. I'm about clayed out from writing this!! So, when I see Clays recommended for the 45ACP-which is which?
