I can't imagine what would have happened if I had hit big bone. This slub went in the front side of the back leg getting mostly hide. It was a little high, slid along punching through just behind the ribs, went through the lungs and misses the off shoulder but stuck just under the skin right above the arm pit. NEVER busted the guts. The deer was kind of curled up causing the wierd bullet path. The only bone it hit was a rib going out.
