A good friend and great turkey hunter I know uses the fighting purr to get turks to come in. If they' re near, but he' s got limited cover, he' ll set up and see if he can get them to come check out the " fight." Purring with any of the calls mentioned by the other turk-o-maniacs here are good, but even better if you got a wing to add some flapping sounds to the " fight." If you don' t have a wing, try flap your hat a few times. He says it' s worked a few times with henned up gobblers.
