I have a two Dillon 550B's for general reloading chores. I have long used a Lee Turret Press for those times when I only want to load a few rounds for testing, etc. Recently, I replaced the Lee Turret press with a new Lee Classic Turret press. For the uninitiated, the Classic is Lee's relatively new Cast Iron frame turret press with a longer stroke so it is more compatible with rifle cartridges.
I just recently set it up and started using it. I was pleasantly surprised when I discovered how much an advancement it is on the very good Lee Turret press. The design is very similar but much refined over the earlier Lee press. It is smoother, more precise feeling, and is very satisfying to use (good tools are ALWAYS more satisfying to use). I definitely recommend the Lee Safety Prime system which is optional (you save money buying for both the large and small primers at the same time). It speeds up the operation a good bit.
For those that are curious, I can say that it is relatively easy to turn out 150-200 rounds per hour (.45 Auto Rim, for example). If you haven't used one of the Lee Turret presses, you can change calibers in seconds, not minutes. That is very useful to me as I reload for a number of different calibers.
All in all, I am MORE than satisfied with my "Upgrade".
