Ipicked up a bowhunting video by Muzzy calledBad To The Bone Bucks 2, great video, and one of the guys called in a monster, was at full draw, and did a soft mouth grunt. No response by the deer. He did it a few more times and no response. Then he finally made a few kissing noises and the buck stopped right there and he shot. So if they don't stop with a grunt, make a few kissing noises, my dad does this too.
