Was going to buy the .223 Dillion Conversion Kit for my 550 when after doing some research I discovered that the 550 Dillon Conversion Kit for 380 ACP uses the same shellplate #3 and locator buttons #3 that .223 Remmington uses. So you can save some money and reload both 380 ACP and .223 Remmington with the same conversion kit. The kit numbers are different but the componet numbers are the same. You just have to buy the "A" powder funnel for the .223.
