They should do this the old fashioned way; stampede the whole herd over a cliff. If it was good enough for neolithic hunters, then it's good enough for you!
I'm much more modern then that. I tie a cheeto on one end of a string and tie the other end to my rifle. Then I just drive near the herd of what ever I'm 'hunting', hang the rifle/bait out the window and wait.
I've never understood the need to pack out an animal.
