I have the right brass so I won't need a forming die as of now... Quality Cartridge does make the brass still. Hopefully you have dies!
I have both the form dies and the reloading dies. It's a cartridge I really like to play with and wish it was still being offered, particularly in a lever action like the Marlin 1894. I explored having one made up with a pistol grip, slender forend and 24 inch barrel, but the cost was prohibitive.
