Not really sure of the deer anatomy, but if you didn't hit the deer perfectly in the middle, would it be better to hit them a little low, or a little high when bow hunting? Which shot has a higher rate of recovering the deer might be a better question.
Low you have the heart and lungs go to bottom of ribs, high u hit what we call no mans land meaning no vitals just meat.
If you are hunting from a tree stand I would rather be a little high as the angle of the shot would still get at least one lung. If you miss low at a steep angle you could miss everything.
Deer tend to duck down and push off as they run at the shot. Its best to aim at the heart area and if they duck then you still hit center or upper lung.
My advice is learn the vital placement like the back of your hand. This will answer your question quite obviously Sent from my iPad using Tapatalk HD
I aim a touch low as in for the heart area. I have yet to see a deer leap from straight legs (they duck to load up their muscles). If they duck at all you still hit lungs.
I always aim just a tad bit low so that if they duck I'm still hitting vitals, if they don't duck I just hit the lower portion of the vitals. That has worked for me so far.
low... like most have said just at the shoulder, slightly behind. If you hit deer high and slice up something in the vitals, the body cavity has to fill before you get real good blood on the ground.
There are plenty of great resources on the internet to learn exactly where to aim for all shot angles. Like Max said, learn it. Learn it before you ever draw your bow on an animal. Its your duty as a bow-hunter to know exactly where to aim before you ever step foot in the woods. Good luck.
This is the best deer anatomy picture I have ever found. I have it saved on my computer for reference.
