these have been very good descriptions of crimping and id just add this for kicks.

the adjustment is really simple to achieve when done the way i do and have done for years.

adjust your body down till it just touches the case mouth and back it up two full turns so it no way contacts the case mouth.
now adjust the boolit seater down to seat the boolit to the desired depth,,,also make sure that the chanelure is rite there where you will want to crimp.
now run the depth adjuster way up so it does not touch the boolit and readjust the body till you get the desired crimp and the case is " rolled " into the chanelure of the boolit.
next with the body locked into place where it gives you the desired crimp,,,spin our boolit seater down to meet the boolit. this is a feel thing that was mentioned but is pretty simple to aquire the feel for. when the boolit seater is in place against the boolit and your body is locked in place for the proper crimp,,,lock the boolit seater in place and withdraw the loaded cartridge.
next put a primed, sized, powder charged cart into the shell holder and place another boolit on top making sure the boolit is straight with the case and pull down on the handle,,,,,,,if everything is correct,,,,,walla there is a seated and crimped cartridge.
repeat till done with your run.

i do this every time i start to seat boolits on any cartridge,,,every time...just so i am certain that every time is done the same way and i always get nice, crimped and good looking and functioning shells.
