RE: Shot placement
I use lungshots.
The problem with neck shots is that you must severe the vertebrae to ensure a clean kill.If the bullet strikes close to the vertebrae,the deer usually falls to the ground stunned.However it is usually up and running again in short order.I have had to track three deer shot in the neck by other people.One had to be shot again and the other two bled out eventualy,but travelled a long ways before we found them.Head shots can be even worse if the jaw is shot off and the animal starves to death.
The lungs are a lot bigger target so the odds of a lost animal are much lower.
