Just curious, what brand of dies were you using? This is nothing that I am familiar with. I'm not claiming to be much familiar with anything other than the brand I usually load with. I load a fair amount of .38 Spl & .357 Mag with the same dies and also .44 Spl & .44 Mag with the same dies, using a single stage press. I have to readjust my dies when I change from one to the other. This might be an interesting concept.
