Lets see. Hole in hole out dead elk. What kind of damage between the holes? Did you have to track a long way? Was there a blood trail? Why do you think the bullet failed? The last two elk I have seen shot, cows, with Barnes TSX bullets small hole in small hole out lots of lung damage and heart damage and both fell within 25 yards. I guess I need more info than two small holes in a dead elk to say failure.
