I have the same problem here. The State demanded that anyone selling black powder has to have a powder bunker where all of it must be kept. Also most insurance companies will not cover stores that sell it.

I order mine through Graf's & Sons or Powder Inc. Last time I tried Powder Inc. they did not have any. Also the other real crime is, when you order black powder and a sub powder, they will not ship the stuff in the same box. They need two hazmat fees that way, yet the powder normally is delivered the same day with one box on top of the other.
