I loaded single stage for years until I began shooting Cowboy Action a couple of years ago. I bought a used Dillon 650 and couldn't be happier. I load 9mm, 38 special, 357 mag, 40 s&w, 45 acp, 45 colt, 223/556 and 308 on it. Takes about two minutes to change from one caliber to the next. Customer service is outstanding and the machines are easy to use and adjust. I would say a 550 but it is manual index and with your boys shooting too the auto index will save a lot of time.
