If your hunting public land bugling will often times scare the bull away. It still works to run along ridge tops bugling before sunrise then once you hear a bull you can creep closer into range and try cow calling. Bulls are starting to get leery of cow calls now also. In limited hunting areas or private land bugling still works pretty effectivly. Depends I guess where you are hunting. I have had bulls bugle at me but I have never called one in all the way.
