Steve,
06 diameter is smaller than 6.5x55, maybe 6.5 Rem. Mag., but they are pretty rare too. I know custom dies are pretty pricy, I had to have one made to form 6.5x58R S&S cases in a couple steps. I made up one for fireforming with about 5 different dies. It formed OK but it was more trouble than it was worth for a rifle I planned to keep.
