What's Everyone Hunting.

[Double Naught Spy]

Who was there, me or you.
I've shot many pigs in the eye, dropped on the spot.
But hey, I've seen it snow the 27th of May before.
I can also say I've seen many times as a guide the
animal turn at the last second and what was a well
aimed lung/heart shot turned into a gut shot.

LOL. Okay, you may have seen it, but as you are talking up its virtues as you are, it is important to note that the eye isn't a vital structure in and of itself. One most certainly can shoot a hog or a deer in the eye and the animal not drop dead as a result. Like you, I have shot many hogs where the bullet initially entered through the eye that dropped on the spot as well (and have the videos on YT to prove it) but "Every time" is one of those absolutist statements that should not be an absolutist statement because it won't always be true, as I noted. I know of at least twice I have seen hogs shot through an eye where the hog did not drop dead because the bullet missed entering the cranial cavity.

It was you who asked

why waste the meat
the head is about the same area in circumference

You indicated that the head is the same area in circumference as the thoracic vitals kill zone on deer or hogs hence why you are saying to take head shots and not thoracic vitals shots and wasting meat, only this is a flat out misleading statement as you seem to be suggesting that the area of vitals is the same between the head and the thorax and that just isn't true. The "head" contains a lot of non-vital area.

Yes, animals do move. Compared to a thoracic vitals shot and a cranial CNS shot, the difference is in the size of the target. The thoracic vitals shot (~4-5x larger vitals target than in the head in deer and more so in hogs) gives the hunter much more room for various errors, either on the part of the hunter, environmentals, & animal movement.
