T.I.
I have them come down 1/3 of the way from the top of the back into the shoulder. Also, I have found waiting for the animal to put its head down improves the result.
The bullet goes through the lower part of the shoulder blade and usually is just under the spine or occasionally clips the bottom of the spine.
The thoracic spine between the shoulder blades is like the master switch to a breaker box. That area between the shoulder blades is about the size of an orange. Impacts in that area put them down instantly.
My favorite placement is quartering towards the hunter, the forward point of the shoulder at the base of the neck with an exit behind the off side shoulder.
So running a bullet diagonally through the same area just under the thoracic spine. That placement also consistently drops them where they stand.
