I was at camp a few years ago with some buddies who were telling me we should all be able to shoot a deer in the head (with gun or muzzleloader) to preserve all the meat. Well, I had a doe come in to within about 10 yards on a slow walk, and completely missed the head shot with my scoped muzzleloader! Needless to say, I won't ever do it again unless the deer is standing still at close range, and even then will probably go for the shoulder.
