. Because I am a squared away guy who likes his gear clean and neat. It's no problem if you clean your press every time you finish using it like I do. I bought that press in 1977 believe it or not and there is no telling how many 10's of thousands of rounds have been loaded on it. I did send it back to Dillon once about ten years ago to be refitted. It came back like new and they didn't charge me a nickel. Can't say enough about their customer service. I also have an old Lyman All American press mounted on that bench, and except for the paint being worn off in places, it is just as clean and I have been loading on it since 1968.
I wish that 550 was a 650, but I don't shoot enough any more to justify doing that now.
