I have had friends that have. Many years ago a buddy took a large bull in early September that was chasing cows. He still had a few velvet strips hanging off the tips of the antlers. My buddy thought that the bull was just being a grumpy old bull. His meat reeked and after a lot of attempts to spice it up he tossed it. The rest were taken right at the end of the first split season. All of them were pushing cows around.
The bull in my avatar was taken on the next to last day of the September season. He was obviously the herd bull and was doing his own thing, but he was not pushing around any of the cows like the smaller bulls. He tasted "caribouy" but not rutty at all. Great breakfast sausage and good loin steaks.
Here he is half dressed in his summer coat. Once half of him was bagged I could drag him out of the water to some higher swamp.
This is what you want to shoot if you are meat hunting. Young dumb bull in velvet. Yum!
