Calling deer in, seems unlikely, but---let's just say I've had some curious experiences. Several times I've unintentionally called in bucks with a varmint call (wounded rabbit), enough times to make me curious. Last deer tag I had, about 11:00 I decided hell with the deer, I'll try calling in a coyote. After 10 minutes here came a decent 4 point--season over! (no coyote!). Why they come to a varmint call is beyond me, but it has happened too many times to be coincidence--there's something going on. Now, I don't think I'd set out deer hunting by calling with a varmint call, but if things are getting boring, give it a try. Likely you'll bring in a coyote, but look hard for a deer before you drill that coyote!
