There are two different hole spacings. One is the spacing on the machine it's self. The other is the spacing on the bottom of the Dillon mounting plates. I can measure off either one. You can also give Dillon a call on the phone (they are there on Saturday - free call) and they will give you more accurate data than I can measure.
