Nice. Most of my shots these days are clean head shots to the brain or high neck shots. Not used to aiming for the lungs anymore.
Love the exit wound.
I am curious what you believe the advantage of a headshot might be. Some put forward the notion that the headshot is more humane than a lung shot; as the result is either an instant kill or a clean miss.
In the real world things don't work out so well. The down side of a head shot is the possibility, or more properly the probability, of a facial wound to that dooms the animal to an agonizingly long death, from starvation or lack of water, while sufferinig unimaginable pain from the gunshot injury. As a result, I consider the head shot marginal, at best, and reserve it for emergencies involving dangerous game and very close range.
Whenever a shot is made on game, we must accept the possibility that we might wound the animal, and while we do everything possible to negate that outcome, the possibility remains all the same. But the successful headshot requires such a fine degree of precision, which it is all but impossible to execute on demand.
Lets examine the problem. Your target is approximately the size of a baseball. If you are shooting off a bench at the range, hitting a stationary baseball with a cold bore shot poses no significant degree of difficulty out to 300 yards if you're a talented marksman with a good rifle. But the animal moves, even while grazing. When he stops to check the breeze, his head turns about 180 degrees; this changes not only the shape but also the size of your target. At long range this becomes an impossible problem even though you are shooting from a solid rested position. But if the range is short, the motion even more difficult to compensate for, unless the animal is moving directly towards you, things happen quickly, and you are not shooting from a solid rested position.
I have no way of knowing how good a shot you are, but I know how good a shot I am. I also know what I cannot do with a rifle, and making a sure kill or a sure miss, with a head shot on a big game animal, regardless of the range I shoot from is something I cannot do. I can miss the center of the lungs by 6" in any direction, and still kill the animal in a humane fashion. If I miss the center of the head by more than an inch on either side of my aiming point, I've got a wounded animal, who can cover a great deal of ground in a short period of time. Even if my lung shot doesn't drop him instantly, his ability to cover ground is greatly diminished, the faster he burns up the oxygen in his blood in a mad run, the quicker his mind becomes confused, then dies.
If you have indeed been fortunate enough to kill an animal or two with a headshot, consider yourself lucky, the odds are stacked against you; so choose a target with a greater margin of error.
