No, I have not. I've called lots of fox and coyote but only tried one other time for Bear. I did have something on its way in but I spooked it when I stood up to leave. It was fairly large and did not sound like a coyote. I know it will work but the wind has to be just right and oddly enough a bear has to be able to hear me. I guess it can be very exciting, they either sneak in or come in charging. I'm taking my .444 just in case they decide not to sneak!
