Well heres how it is. A well placed shot would be in the lungs or the heart and nothing is going to live long without those two organs. What people tend to forget is that deer have the same organs as us humans have. If you collapse one lung the deer can get farther and live a little longer but not live for long. Maybe 10 minutes tops. A heart shot is death, almost instantly. If you hit a artery your looking at 5 minutes tops. Both lungs hit, that deer is dying very fast, it can't breath. If you miss these critical kill spots you may have a problem. I shot a deer three years ago and to this day I still see that doe. If you miss the critical spots you better hope you hit a spot that will bleed out. Just like us, if you loose enough blood the body goes into shock which leads to cardiac arrest. Once in shock you aren't moving. So the moral is if you don't hit the critical kill spots, or a spot that will bleed good, you could be in trouble. Your best bet is to sit and hope he/she sits too for about an hour if your not 100% sure of your shot placement. You don't want to have to follow a deer across the country.
