When I see certain powders that I want that's not commonly found, I usually buy it and try not to look at the price tag. There's a fellow that shows up at certain gun shows that has many of these "unattainable" powders. So I try to have a couple $100 set aside for powder purchases come gun show time.
I had difficulty getting 215 primers for a while. A friend picked some up for me at the Tulsa gun show. Now I see it fairly often. Go figure.
My advice is to be prepared when you attend gun shows, the gun shows brings lots of vendors. Sometimes internet searches work too.
