Do it.....I ran a 550 for 30 years. Switched to 650 to automate making VT brass and never looked back. Shoulda done it years ago.While I sometimes think an upgrade from my Dillon 550 presses would be nice, I am kind of stuck with what I have. I have two 550 presses, and to upgrade to say a 750, I would need to sell everything I have and then basically start over, shell plates, toolheads, etc. I even considered doing so but after researching the Dillons, as well as RCBS, Hornady, I decided that I have what I have.
Hmmm...now maybe a 1050?
