Sorry, I meant to address two of the issues you brought up, but was having internet connection problems.
Anyway, I have never had an issue with the dies loosing adjustment. Well, I have had that issue with the powder cop die I have with the lock ring. If I were to go and look up the right sized wrench and tighten it down with a wrench, it would likely hold. Even hard finger tight, it loosens on occasion. The Lee dies with the O-ring stay put finger tightened.
As to solid feel, I like the feel of mine. Yes, the turret lifts slightly when the case is pressed into the die. It is not really noticeable by feel, and it lifts the same amount each time, so it is a non issue. I get OALs right on the money every time, and flaring is consistent.
To get the full benefit of a turret you will need to prime on press and drop powder during expansion. If you don't have a press activated powder measure, I suggest you get one. It is a real time saver. I have the Lee auto drum. Much better than the Auto disc IMO. I load primers into the primer cup by hand. I use a saucer shaped wooden bowl I turned to make picking one primer at a time easier. It is still much faster than the extra steps involved in off press priming. The Safety Prime gets mixed reviews, so I just load them by hand.
Having said all this, if you want to either drop powder, or prime off press, you can. You will still save time, just not as much. In fact, you can disable the auto index in seconds, and use the press like a single stage, if you want. I do this for 30-06.
