Any deer that gets within 200 yards... I call "dead meat".
Seriously though, I've also tried calls, including grunt calls, doe bleats and fawn distress, and have never had any noticeable luck with any of them. It's probably because I don't really know how or when to use them, but now I don't bother. I've always had more success just sitting still and quiet in an area a know deer to frequent.
