I agree,agree and then very slightly disagree with what you say.
First,Agree.On a bear it's my thoughts (based on experience)that trying to pop the spinal cord with a neck shot is a little risky.With the last bear I shot,round one went in about an inch behind and slightly above the left eye.(I was trying to bust the brain from 42yds).The ball went through the neck not far below the spinal column and went out in the right flank.Round two entered almost in the same hole as round one,maybe 1/4th inch lower,traversed the neck and lodged just about in the anus.Still no damage to the spine,and the bear was still very active.Round three was in the brain,and that wound it up.(I'd moved up to 18-20 yards).
Second,Agree.It seems that if you can turn a deer's heart to jelly,it will pretty well drop in place,but even a good double lung shot and the deer is subject to run some distance,even 100+yds or so.
Third,Slightly Disagree. On a bear I think I've observed that a good double lung shot will drop him in place as well as a direct heart plastering job.Notice that I said "I think I've observed".A few yards running,maybe,but not very far. However,hit just one lung and you better pack a lunch to take looking for him.
Now,if I could figure out how and where to hit a bear and make him run to within a few yards of the truck before dropping... :: :grin.:
