JR,
My son hunts for the meat - not for any trophy. He said it was a single clean shot through the lungs. Regarding his rifle, I am not sure of the caliber. I think it may have been the same rifle in this hunt a few years ago:
Perhaps you may recognize it.
Regarding the meat, he eats EVERYTHING, and is really looking forward to Elk Liver. After a diet of Bison or Elk, he really has a hard digestive time eating store bought beef afterwards.
