RE: Elephants
A year ago Chuck Adams wrote an article in Bowhunting World about how he was invited to an African Country (Tanzania?) to see if an archery season for African Elephants was possible. In his professional opinion, and let's face it he isthe pro, that hunting Elephant with abow is borderline unethical. After two shots The PH ended up having to finish the animal. I believe he was using a one-off 100lb+ bow with special arrows and the like.
While cutting open the animal, he described how the animals 3" wide ribs basically overlapped eachother dispersing enough energy to minimize what ever energy was left in the arrow for penetration.
Personally, I have no interest in going to Africa to hunt game or otherwise and likewise have no intrest in shooting anElephant. However I am glad there are opportunities toharvest them witha gun if folks so choose to.
I will take Chuck's word for it thatthe technology is quite their yet to be harvesting an Elephant with a bow.
