Younger bears as well as hungry bears will come in to most any predator calls. Older bears will if they are really close by. Fawn bleats and distressed rabbit has called in a few for me years ago when I hunted bear. Called a few in with doe bleats as well. Never had one come in to a turkey call though. New one on me. Glad none have. A turkey load could kill one if you hit it JUST RIGHT but more than likely you will just pee it off!
