Gunner,I suggest you buy the book "Elephant" by Craig Boddington. In it he gives the run down on elephant hunting in Africa today. The book came out BEFORE Botswana closed elephant hunting.
Yup,either the .460 Wby or the .450 Howell.
Boddington made my OCD kick in with his story about the big croc he shot in Africa. Now I think every damn big bore African rifle needs to shoot walnut sized groups....
