I am not up to date on what the 458 will do with newer powders. If you can safely get a 500 grain bullet up to about 2150- 2200 fps it would perform well on the largest game animals.

If I were looking for a 458 caliber I would probably go for one based on a full length 375 case as pressure will probably be lower under some African hunting conditions this could be a factor.

It has been my experience if you want to be in control of a situation when things go bad you want something that will penetrate fully and drill as straight of a hole as possible. Bullet construction and design is also critical and experience has shown that a blunt nose will drill straighter hole than a round nose that can more easily be be steered off course.
