Actually, I read this thread from start to finish and learned something...

Having used UNIVERSAL for quite a while I finally got a 1 lb. container of CLAYS to use for a specific application. Since I don't reload shotgun I've yet to try INTERNATIONAL, but can certainly see how someone could easily get confused when the subject of using "Clays" comes up.

Almost like the numbered rifle powders, i.e., H4895 vs. IMR4895...?

Cheers!

P.S. At least those Clays containers are clearly marked as being CLAYS, UNIVERSAL & INTERNATIONAL.
