From what I've read, I've come to the conclusion that a lot of the bad reputation given to the .458 was because when it was first introduced, the bullets loaded by the factory were too soft, and either over expanded or came apart. Either way, penetration was woefully inadequate. With the super premium bullets available today. that's no longer an issue, IMO. I also recall reading that the powder used when it first came out wasn't reliable, in that tha African heat caused pressure problems, and the older powder also had a tendency to clump together in the case causing inconsistant ignition.

With today's selection of bullets, and modern powders, I think the 458 is up to the task when it comes to DG, and wouldn't hesitate to use it.
