There are a lot of outfits doing archery hunts in Africa for all of the dangerous game including elephant. And they do these hunts very successfully. A hunter that knows what they are doing is every bit as deadly with a bow as someone else can be with a rifle. And a well placed arrow with a sharp broadhead will kill just as reliably as a bullet. Anybody that thinks this is not so is ignorant about the subject. Fred Bear was killing lions, tigers and elephant back in the 1960s with a recurve. Howard Hill did the same thing in the 1950s. Millions of big game animals including elephant and rhino have been killed in the course of history with arrows. Think about that for a minute, the modern sporting rifle with smokeless powder is not much more than 120 years old. Before that it was blackpowder firearms and archery.
I suggest anybody that thinks I am full of crap take a moment and look at the SCI record books and see just how many lions, elephant, cape buffalo, rhino and leopard (the African Big Five) have been taken with archery gear. Newsflash, there are hundreds of entries and the only entries that can be entered are animals killed solely with archery and not finished by a PH with a rifle. Just sayin...
