On bucks I like to break shoulder bones. I don't like stuff to run off after I squeeze the trigger.
How far have you found that they run usually when lung shot vs shoulder shot? Personally I have seen next to no difference unless both shoulder bones are completely broke. That is, compared to being shot in the forward lung area right behind the shoulder as opposed to lungs back near the liver. Those lung shot further back can run a ways.
Here is a shoulder shot by one of my nephews with a .260 and Barnes TTSX 100 grain. Pretty typical result.
Most of the places we hunt are narrow roads cut into thorn brush. So, shoulder shots to drop them where they stand is important to avoid having to crawl in the thorn brush with the Texas earth worms. A young nephew got excited and shot a buck in the lungs last year. It took four experienced men an hour and a half to find it laying only 50 yards into the brush.
Here is my wife with a .308 and 130 grain Barnes TTSX to the shoulder. The distance is just a bit beyond 200 yards. As can be seen, the brush line is a matter of feet away. She does a nice job shooting with her GAP .308.
