A properly shaped charge would pass right through his neck expanding on the way. No projectile needed. I am not saying there wasn't a projectile, but if the "shot" came from the microphone attached to him, then it didn't need one and furthermore the risk of that projectile hitting the man asking the questions (Zin) would have been a problem.
Right. A shaped charge produces its own "projectile" from the liner in it, assuming it was made as a "mini" version of a common military shaped charge.
