One thing is for sure, broadside shots have a very good chance of hitting TWO lungs and the frontal shot has nearly zero chance of hitting TWO lungs. Why anyone wants to argue that the frontal shot is as high of a percentage shot as the broadside shot is, is beyond me.
On a broadside elk, the lung area is about 16"-18" and if ya get one, chances are very high that you'll get'em both. Can't do that from the front.
