I have to agree with Grouperhead,
the best shot is a good lung shot or if you want to anchor them quick a double shoulder shot!
Neck or head shots are only good when they are PERFECT!
To me they are not worth the risk of wounding an animal.
As far as wasting meat, there is good meat on the neck too,
and a lung shot, even with my 7MM mag wastes very little or no meat. So it is the safest shot that you can take!
