when I travel to my main home in Pennsylvania I shall dig out the scrap book scan a few pictures then send them along to you for the posting.
I hunted Zimbabawe for Old George with my bow twice. Twice I can out of it with the skull mount. I was then shooting an 82# Hoyt compound and Alum. shafts. The first bull I had a complete passthru with both lungs being hit. He and his commrade ran off into the dust. We allowed 1 hour then trailed him up ...only to find him within 50 yards stone dead. My second bull was not a passthru but I collapsed 1 lung and hit the top of his heart...this old boy ran almost 300 yds out into the ( he was in sight the entire time in short grass but laid up in head high reeds about 50 yards square. After waiting we circled to get the wind correct then my PH started in with me carrying a rifle the head tracker had been carrying right behind him. We literally walked up to within 10 feet of him before we saw him. He too was dead.
Intrestingly both bulls died just as fast as they would have with a single 458 Lott thru their lungs.
Nitro, you mentioned a second buff being wounded an tracked for 2 days. I doubt that it was a lethal hit with that shaft... poor shooting I presume for had the archer placed his shaft in a vital that buff wouldn't have cared if that vital was damaged by bullet or shaft.
With the popularity of archery hunting these days I honestly believe that more and more DG will be offered by companies looking to fill the bookings.
