Star73,
I don't claim to be an expert on Star history, but the Super Star Conversions was Dillons first entry into the reloading business, and my understanding is that he was on friendly terms with Star at the time. The conversions was a group of parts that converted a Star Universal to load .223. According to Dillon's website, he sold less than 100 of them. I have a partial set of the parts. I keep looking for the rest, but haven't made much progress.
The following is from Dillon's website:
The Highly Irregular and Somewhat Improbable
History of Dillon Precision Products
By Mike Dillon
I got into the reloading equipment business purely by accident. It started when a friend of mine died in an airplane crash – MY airplane. A few other friends of his and I spent four or five months closing up his machine shop business and selling off all the tools for his widow. When we were finished, she said, “I guess I owe you an airplane.” I answered, “No you don’t. I didn’t lend it to you. I lent it to your husband. That was between him and me. But I WOULD like his Thompson submachine gun.” The Tommy gun came with a star loading tool, so I became a progressive reloader.
Shortly thereafter, I bought an M-16, and wanted to load .223 ammo progressively, but Star said it wasn’t possible to do it with their tool. They said, “If you want to try it, we’ll sell you a .380 shellplate and you can try to make it work.” So I went to a machinist and cut down an RCBS die, ground the hardcoat off of the outside and had him thread it to the weird thread size that Star dies used and I made the damn thing work. I changed the link-arms to give it a little more stroke and came up with a kit so my friends could convert their machines.
My friend Peter Kokalis was ridiculing me and sarcastically suggested marketing my kit as the “Superstar Conversion,” which I did. Maybe 100 or so kits were sold, but soon people started asking me for a conversion to load .30-06 rifle ammunition on the Star machine. That’s when I decided to make my own reloader. The RL-1000 was the first full-fledged Dillon Precision product. Manufacture started out in my garage, then we moved into a small shop. We started the company on a $30,000 loan against our house.
