with progressive presses you need dies and conversion kits for the new calibers. ive only got experience with the dillon xl650 progressive. i load a lot of different calibers and ive got parts for a lot of different calibers that all i really need for a new caliber is the shellplate as the other parts have hit critical mass and i can swap in and out for just about any caliber and a few dillon doesnt support...
