As a kid I was taught to shoot 'em in the shoulder so they wouldn't go anywhere and get claimed by someone else. That was in the good old days when we hunted in the mountains of N Central PA. Literally a guy behind every tree. Still remember the first deer I shot through he lungs - couldn't believe I pulled the trigger and it ran away! Of course it was plenty dead and less messy than that square in the shoulder shot. I'll still do it if I need the critter to stay put and I don't have a rest for a clear neck shot. Most of the time though we just put a nice hole through both lungs and collect them a few yards later.
