I recently went to Africa and harvested an Eland and a Sable.
In the Eland, as he fell and collapsed, he fell on the remaining shaft protruding and shoved the arrow all the way in. You can see in one pic the "bump" of the broadhead almost protruding out the other side. The Sable, I think, broke the shaft off as he ran after the hit.
The broad heads performed great! Love the broadheads and keep up the good work.
