I love my Dillon 550. I loaded 200 rounds of 9mm and 1,229 rounds of 223. I load the 9mm on my Lee classic turret and the 223 on my 550. I actually love both presses but the 550 sure makes quick work of 1,200 rounds.
But where would be the enjoyment of reloading in that?
Granted, I love my Dillon XL650 with case feeder but I still take it a little slower and routinely check powder charges and when the finished case bin is full I stop and do a full inspection of every round. For me it's not about getting 1000 rounds done in the fastest time possible but getting 1000 rounds done in a more efficient manner and still maintain near single stage quality and round to round consistency.
