Interesting topic, I have often thought about posting a topic about how many hunters have actually been successful grunting a buck in. Well I can tell ya that I have heard alot of bucks grunting, and every time, they were always chasing does during the peak of the rut. Its always those short repeated grunts, and never those long drawn out grunts that you hear those guys on the videos doing.
I have more different grunt tubes than I care to mention. I have grunted at lone bucks, bucks with does, bucks with other bucks, and used ever tone imaginable to try to get them into shooting range without success.
I have also heard fawn bleats, but never a doe bleat in heat. I heard something this past year that I think was whats called a grunt, snort, wheeze and it was a very strange sound, a sound that you would never expect a deer to make.
Like I said, Ive never had any success calling one in, but I am gonna to keep trying.
