Lol, I agree, most people can't hit the broadside of a barn whether it be bow or firearm. Other than that I've always shot for the easiest kill on everything. Seems to me that a good head shot would be more merciful than a lung shot where the deer can still run for miles.
To me the shot taken depends more on the ability of the hunter to hit his target consistantly. As someone stated before the brain is a vital organ and thus a valid target. It is a legal shot so then it boils down to a matter of personal ethics just like keeping 10# walleyes does.
Heh, all the people that bitch about an arrow sticking out of an animal would be bitching one hell of a lot more if they could acually see the number of deer wounded by firearms. If every shot left a big circle of blaze orange on a deer there'd be one hell of a lot of deer running around with blaze orange spots. Arrows are a ton more noticable than a small gunshot hole.
One thing I hope kids learn here at this site is that "Legal isn't always ethical and ethical isn't always legal". Probably to advanced a concept for most kids but one they need to learn and understand.
As for out sport as we know it today. Our sport is not as we knew it 50 years ago and in another 50 most of us wouldn't recognize it. Everything changes. Somne aspects will be better, some will be worse.
While the primary body shot may be the overall best it's not the only kill shot.
