Got my last through act 2. Think it was just pure luck I got to kill each one over a short period of few hours.

They spawn randomly. I got my achievement half way through my second Act 6 playthrough (Recruit first, then Veteran). If you haven't got it after 6 or 7 playthroughs, I'm wondering you're aren't getting the final bullet in them to get the kill.
