Dan, if you would like any more references for your edification you might look up the 30 Reese. It was cooked up by a guy named Carson Reese from Lebanon, Mo a few years ago to do somewhat the same as you have intended. He did a lot of development and it has to be somewhere on the web. We did some shooting together from time to time and he handed me a set of dies he had Hornady make. To this point I have yet to enter the foray so to speak. Guys like you might keep prodding me though.
