Ummmmmmmm OK Gentlemen! I have 2 model 70 Winchester .458 magnum rifles in our vault and 2 of those .416's as well, only one is a .416 Rem. mag model 70 Winchester and the other is a .416 Rigby.
Some of the tests I have run and others such as Mike La Grange tell me all I need to know about penetration. The .416 calibers simply will out penetrate those larger slugs in the .458 Win mag. Also if you really want to gain the power from using the .458 bullet, one must jump to the Lott or Watts to do so.
We all know the .458 magnum has the power edge over the .416 caliber but that is NOT the frigging question is it! Some one not long ago put pictures up of the elephant that was shot in the rearend and the .416 Rem mag bullet traveled 22 feet and was recovered in the one tusk of the animal. NO .458 mag bullet is going to do that for a fact, not even an Aussie 550 grain slug.
