i will admit i didnt read every post here, but got the idea.
one has to remember with hunting shows, they have the ability to edit. that means a gut shot animal that isnt recovered will not make the show, so sure all the animal were dead, the ones they found that is.
i have had major hide damage with fmj's, hit some of the bigger bones and the bone fragments blow huge holes in the hide. i have rarely lost a dog shot with an expanding bullet.
