This seems to be every bow hunters dream is to take a herd bull. Most don't want it bad enough to go the extra mile and push themselves for the big one. That is the thing I have done for 45 years of bow hunting is to be able to pass on lesser bulls to get to the big ones.
Herd bulls can be counted on to be aggressive and on the move all the time. Use that to your advantage by always getting into his face with small bull sounds and lost cow sounds. If you can get into the magic 50 yard range you have a better chance of the bull coming your way and not heading out of the country. The use of the Glunk when you are within the herd can make the herd bull lose it and come running without thinking giving you that close in shot.
