I have this one;

RCBS calls it a case trimmer, it is not. It IS a case prep tool that works quite well. The 5 stations all rotate at once, slowly, and have 8-32 female threads on the tool points. That accommodates the primer pocket brushes, and other case prep tools. Including the primer flash hole uniformers. I use mine for when I'm going to do match case prep, or for my hunting rounds.

The RCBS precision case mic, is what I use, for .223 and .308.

It uses a factory loaded round, or a new case loaded by you, then fired in your rifle to tell you exactly what your headspace is. Then, you can set your full length die to just bump the shoulder back 2 or 3 thousandths. This vastly minimizes case stretch, and eliminates case head separations. It also makes the shell a tighter fit in the chamber, which aligns the bullet better in the chamber.

It also has a comparator as part of it, BUT if your bullet has a different ogive,( the portion of the bullet from the full diameter on the front sides of the bullet, to the tip/point), than the one on the comparator, it is only close to where your rifling actually begins.
