I bought Goex from Crater Fireworks just before the well ran dry after the Goex plant explosion, I looked at at least a dozen other dealers sites and all were sold out, he was the only one that still had Goex in stock. I think it was his company's name, people will overlook a fireworks place when they are searching for black ppowder.
Nice guy, quick shipping althought there are no price breaks for hazmat or shipping. My $18 a pound powder was $30 to my door, high compared to old prices of just a few years ago but in line with what the same stuff would cost me now. At the rate I shoot I probably have a lifetime supply with close to 25# held in reserve.
