My 300wm used to bowl little bodied TX deer over when hit in the shoulder. My 6.5cm had one run about 40 yards with liquified heart and lungs. It hemorraged where it fell and looked like the prom scene from Carrie. Both deer were equally dead, the 300wm just seemed to wreak a little secondary bone damage on the off shoulder. But the 6.5 was much closer shot with a bonded bullet so I'm not surprised it passed through easier.
