Re: Lift Powder grain size OD

 See:

http://www.powderinc.com/blackpowder.htm#FIREWORKS%20POWDER

And:

http://members.aol.com/illinewek/faqs/bptypes.htm

  Note where the chart says "Blasting Grade Black Powder" it is also
referring to fireworks grade. The "A" series of powders are generally
unglazed and the "G" series powders are glazed. ( Duh. G = glazed powder )
Also note that the screen sizes listed are U.S. Standard and their opening
sizes I will let you look up on your own. The second cited page is a pretty
good one for the rest of you pyro junkies out there.
