That's the "stepped" sizer sleeve mentioned earlier, but how does one adjust the
crimping force/dimension once the shoulder bottoms out on the case mouth?

I don't know about a stepped sleeve. The new Redding two ring sizers have what amounts to stepped carbide sleeves in that they have two sizing rings with the upper one narrower than the lower one for slightly tapered auto pistol rounds.

The Lee Carbide FCD has a single carbide ring at the bottom that ensures the cartridge does not exceed a dimension that will fit a SAAMI compliant minimum chamber. The crimp ring at the top is hardened seamless steel tubing and has either a taper or a roll crimp profile ground into its inside bottom edge, depending upon the cartridge it is intended for. That ring floats and is removable from the die by unscrewing the aluminum hold-down plug in the top of the die. That same plug serves as a vertical stop for the crimp ring to bear against during crimping and how high or low you set it determines how hard a crimp you get. There is a rubber O-ring in a groove near the bottom edge of that plug so that it doesn't move from the position you set it to.
