I learn every day.
RE the DG stuff though not running brain shots on other stuff, (IE I get the elephant stuff, seems lazy that folks don't research and practice but thats another soap box of mine) Why don't you shoot lion/leop/buff etc.. in the head? There is NO issue if you brain those? Again simply the non ability of shooters is my guess? And much larger room for error on a low shoulder shot? Or do you strive for the high one and if you miss top of heart, thats fine, because the chances of damaging the spine are much higher?
I suspect since I was a kid and my mentor taught me brain shots on deer as I grew up, that I"m a bit biased to that shot and how easy it is to locate the brain and that you either know you'll make the shot or you pass it up for the next shot.
