Don't you know that the 458 is a whimp gun?Sure its ok for short range plains game..

No, Really the 458 Win Mag is a very underestimated cartridge. It gets a lot of bad press form the big bore fans but it can certainly hold it own. I am suprised that it does not get more use for the big Bears but I guess its lack of long range capabiltiy or trajectory, makes it less than ideal for a combo hunt in Alaska or BC.
