Why would a short action be any advantage in any big game rifle? I think some of you have way too much time on your hands and need a full time job!

It's in the shooter's mind, Ray. See...when that shooter is pulling the trigger, he or she is thinking about that..."more efficient column of powder in the case." At that nirvana moment one has forgotten that one is using the same bullet used in the longer case. Also, as we all may already know, that long bolt throw is so long that the fist around the bolt's handle will hit one's chest.
