I saw it at a hardware store out by Houghton Rd and I-10. I can't remember the name of the store though, but if you Google reloading / Tucson it should come up. They had quite a bit, I bought some, and from the looks of it, it had been on the shelf for a while. It was dusty, as in the powder being having red dusty appearance. It shot ok, but you could tell it was getting past it's prime, smelled kind of off.
