Send me a PM about reloading steel cases if your truly interested, I can give you the run down. But after you hear the process, you'll likley abandon the idea. It's not easy, and no matter what caliber, the hunt for brass cases is generally a lot easy than removing the berdan primers and making new flash holes, just for some cases that may last you 3-4 reloads tops, and with putting added stress on your press and dies, and not fully sealing the chamber. It can be done out of pure necessity, but not as a normal alternative.
