{{#invoke:Infobox|infobox}} The .460 Weatherby Magnum is a belted, bottlenecked rifle cartridge, developed by Roy Weatherby in 1957. The cartridge is based on the .378 Weatherby Magnum necked up to accept the {{safesubst:#invoke:convert|convert}} bullet. The original .378 Weatherby Magnum parent case was inspired by the .416 Rigby.<ref name="nioa">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The .460 Weatherby Magnum was designed as an African dangerous game rifle cartridge for the hunting of heavy, thick skinned dangerous game.

The .460 Weatherby Magnum was the world's most powerful commercially available sporting cartridge for 29 years until the advent of the .700 Nitro Express by Holland & Holland, London, England, in 1988 developing approximately an average of 8,900 foot-pounds force (12,100 J) of muzzle energy with a 1,000 gr (65 g) bullet at 2,000 ft/s (610 m/s). However handloaders can push the cartridge to generate as much as 15,000 foot-pounds (20,000 J) of energy in a modern bolt action, by using a 1,000 gr (65 g) bullet fired at 2,600 ft/s (792 m/s). However, doing so necessitates a rifle so heavy it is almost inoperable for hunting purposes. The .700 Nitro Express was itself eclipsed in only five years by the 1993 introduction by A-Square of the .577 Tyrannosaur. The .577 T-Rex develops approximately 10,180 foot-pounds force (13,800 J) with a velocity of 2,460 ft/s (750 m/s).
