Thanks for the source Atllaw.  I thought this stuff was supposed to be a high end product like swiss.  Anybody know how it compares to Goex.  I don't want to make the same mistake I made like when I  bought Elephant powder which was so weak by the time you used enough to equal Goex, it was actually a lot more expensive.  
"FG is used for cannons and firearms.
FA is used for "lift" and "burst " charges in fireworks."   
I know a guy who uses FAAA (3FA?) and says it's about half way between 1f and cannon. 
Only difference is it's not graphite coated (thats what the G is for).  It's not as consistent grain size and you will have more powder at the bottom of the can.
