Because of the circular shape, we call it the "Crecent Cut Club" in my family. Four of my cousins belong to it. Two, because they shoot cock-eyed, right handed and left eye to aim. My brother and I do not belong to the club but I have had my thumb in the wrong position and wrapped myself in the nose pretty good.
On the hunting shows alot of pro hunters have done it. Dave Watson did it shooting uphill at an extreme angle off of shooting sticks set to low. As mentioned before, Jim Shockey does it so often that in the opening of his show the last picture of him he has a fresh one.
