Maybe because I so lover the Star progressive where caliber conversion costs exceeded $350 I've never been much concerned about the cost of caliber conversion on the Dillon. On both the Dillon and RCBS you'd need a shell plate and a tool head. The Dillon has the powder measure set up on the plate. The RCBS does not. The powder measure on the RCBS is screwed directly into the top of the press and is not part of the removable tool head. A clever arrangement actually. I don't remember how the Dillon works but on the RCBS the powder measure does not expand the case mouth. You have to use a die to do that. There are four die positions on the RCBS (not counting the powder measure which isn't part of the head anyway). I much prefer separate bullet seating followed by crimping. Just easier to set up, I think.
