Yes, it is a great data base and I have downloaded every picture into my files! (just incase that site becomes unavailable?   I am constantly adding stuff in my files every chance I get!

That yellow dust stuff eludes me, I have never seen any for sale.  I am still wondering why it is in the powders?  Is it an identifier?  Is it a flash suppressant?  (Only seen in Commercial Loads so far)
