We both took waterbuck and IMO they were the toughest animals we each took. This is my brothers at 200 yards, the tbbc hit behind the shoulder but penetrated across and broke the far shoulder. The buck ran a ways before dropping-the bullet was part of the shoulder by then and rather tormented--to the point that even the round shank had become oval in shape, but not come apart. You can actually see the entry about mid height and behind the shoulder.
