I just picked up a call with a horn on it to duplicate the snort-wheeze. It sounds true. I' ve heard bucks in the wild do this. If you hear this in the woods, you' ve got yourself one p-off' d buck challenging another....sure to hear a fight immediately after that sound. I' ve put it in my simulated fight arsinal. Haven' t drawn anything in yet but I do know this happens in the wild right before a fight.
