A rib cage shot even on an elk is a soft target & easily penetrated by any reasonable C&C bullet. Even my old 7x57 with the Sierra 160gr will easily completely penetrate an elks rib cage. The real test of a bullet on an elk is it's ability to penetrate on an acute angled shots where muscle mass & heavy bone are encountered. From the front or rear. We have found in a 30 cal a bullet like the Barnes 150gr TSX will penetrate threw these angled shots & on out the other side. After hunting for days & dead tired your presented with a tough angled shot threw an opening in a Willow or Aspen thicket your hunt success absolutely depends on deep penetration.
