Most of the people up a creek with no RUM brass are newcomers to the cartridge. When I first started shhoting them, brass was 38 bucks per 50 and readily available. Now I see gougers selling it for highly inflated prices. I still am on the lookout, but I really don't need any. I'll pay a fair price. It's good for trading also. Kinda like 215 primers which I also layer in a good supply of years ago. But again, I add more if the price is right. mtmuley
