The.257 Weatherby Magnum is part of the Weatherby series of hunting cartridges, which are distinguished by its trademark double-radius shoulder, brass belt, and large case capacity.

The top limit of 180kg (400lb) is still considered safe. They were used to kill a rhinoceros by Roy Weatherby himself just to show that it can be done.
