<< Another advantage of ejectors is that, when you want to grab the cases you can catch them 1/2 way out and not have to fumble about with the doll's head or Greener cross bolt extension (what is the proper name for that?). >>

The proper term for doll's head is "doll's head". The proper term for a Greener cross bolt extension is "Greener cross bolt extension".

(Sorry, I just couldn't resist.)
