I have a 1 stage Lee Press. Was actually a gift from my wife. I use a Dillon LX650 for my .223 reloading. I decided that I could use this Lee to just deprime. I have no experience with the Lee. What do I need to get, so that the case holder holds .223? The press case holder is too big for this cal. I'm sure it's something easy, but the instructions are not very good. Is there a Cal. conversion kit or something? Thanks.
