I've used that high shoulder shot as well, and you're right. They are on the ground as soon as you pull the trigger. Although they are not always dead I noticed.

I forget the name of that bone you are actually busting when you do that high shoulder shot. This web site listed has some good information for those of you that might not be fully aware of all the integral parts of the deer's body.
