the pic does show just how low the spine is in the body, I knew it was low, but thats a good example.
Yup.
The whole top 1/3 of the chest if off limits.
The bad news is that a hit upthere looks good, adn will even leave a good blood trail after a few dozen yards whenenough blood finally soaks into the fur so that more blood can run down to the ground and be seen on the trail. A deer with a muscle hit that bleeds well can be recovered if it is pushed and kept bleeding by motion and good blood pressure. You just may have to follow it a few hundred yards, and be prepared to shoot again.
