In 25+ Years of Texas hunting, I have yet to hear one grunting. I have carried a grunt call the last two years and have grunted to 30 or more out of range bucks around and during the peak of the rut. While I have never had one become alarmed, I have only had one respond postively to it. It was a mature dominant buck during the rut that came right to me from being out 60-70 yards. And who knows, maybe he would have taken the same travel path anyway. The rest have bascially ignored it.
I am sure some marketing guy will tell me that I could be more successful if I bought his brand or at least bought a tape from his company to learn how to properly use the thing.<img src=icon_smile_big.gif border=0 align=middle>
