RE: Shot placement for dropping deer in thier tracks
If you just "have to" drop them where they stand the high shoulder shot would be the one I would recommend. Having seen botched head and neck shots it just something I don't freely suggest.
I personally feel the same as Stubblejumper with a double lung I have needed very little tracking abilities to collect my harvests and meat lose is a non-issue. That being said I have taken a number of animals on quartering away shots where the bullet enters the ribs through the lungs and out the opposing shoulder and it works very well. This shot will ruin some meat in the opposing shoulder though.
