Here in Arizona, I hear the same rap: need a powder bunker, fire codes, etc.

Check to see if you have NMLRA: National Muzzle Loading Rifle Association events near you. Ifyou do, you can usually pick-up powder there. The NMLRA has a annual event near me in December. Ibuyenough Goex to last the year and avoid the hazmat fees that way.
