mauser06,the "magic" spot your looking for is a shot high in the lungs.The shock to the spine knocks them right down.The expansion of the bullet blows the ribs & the lungs right out.99.9% of the time deer do not get up,if they do a blind man could fowllow the blood trail.I shot a large 8 point this year facing me in the neck BUT I was shooting off sand bags.I shoot a 7mm Mag. with handload 140gr. Nosler Ballistic Tips.Broadside high lung shots are increadible & I would take them everytime if the animal offered it.
