I may have answered my own question on where to buy black powder so I'll offer up a source I have used in the past when I was an active competitor in the BPCR game. When shooting long range black powder cartridge rifle in the nineties, I used to go through a lot of Goex cartridge grade powder and bought most of it from BuffaloArms.com in Idaho. I would buy it by the case from them in Raton, NM at the NRA National Matches.
While purchasing some other items from them recently, I notice that they are still suppling black powder and will ship anywhere in the U.S.. The prices aren't too bad considering the hazmat fees and such. Minimum order is 5lbs mix and match and max order is 25lbs. Shipping to Havasu is about $48 for five 1 pound cans and prices run about $19.50 for Goex to $20 for Swiss. Shipping is via FedEx ground.
I have done a lot of business with these folks over the years and can heartily recommend them.
