Be careful and you can start on a Dillon 550. You can start off slow on it. Fast on a Lyman turret press or a Rockchucker is 125 rounds and hour. Slow on a Dillon 550 is 200 rounds an hour.
Do the math. What is your time worth? Wish I would have spent the extra money on the Dillon on my first press.
Ask yourself - how many used Dillon presses do you ever see? Lots of Rockchuckers, Lymans T-Mags, and Lee progressives on eBay. That should be a clue to you.
People buy Dillon and keep them. Nuff said!
