Only had it happen once.....And it was an accident. Big doe at 10 yards. I was up about 20 feet in a stand and She was darn near broadside. I figured on driving the arrow from the upper part of the rib cage on entry down and out the armpit on exit. That shot had always worked before.
For whatever reason, just as I released the arrow, she swung her head around to look behind her. The arrow flew true but her head was in the way by the time it traveled those ten yards.
Hit her right behind the ear where the spine and skull connect......I disconnected it. Had to finish her off with the knife.
Not a shot I have ever thought about taking. And not a shot I will ever intentionally take again.
I like to ventilate both lungs. In the thick stuff I hunt, I sometimes don't see them fall.....But I almost always hear them fall.
