I finally received my SDB the other day that came with the 380 auto dies set up from the factory. I also ordered .40 cal dies and tool head, everything is here but I have no idea how to set up the .40 cal system so all I have to do is switch out tool heads. There is nothing in the manual or on line about setting up additional dies. I've been on the computer all day researching but fell short. I dont know if its as simple as installing the dies into the right holes and getting it close enough or what. Was hoping someone could help. Thanks in advance!
