The .460 Weatherby Magnum compares well with the classic English big bore cartridges; it exceeds all these cartridges in velocity, energy, trajectory and penetration. Cartridges such as the .500 Jeffery, .500 Nitro Express, .505 Gibbs, .577 Nitro Express, .600 Nitro Express do however provide a larger diameter bullet while the latter two cartridges are also capable of launching heavier bullets than the .460 Weatherby Magnum. At present only the "modern" classic .700 Nitro Express exceeds the performance of the .460 Weatherby and then in only a single category: energy. Cartridges such as the .475 A&M Magnum, .500 A-Square, and the .550 Magnum which are based on the .460 Weatherby Magnum can exceed the performance of the parent cartridge, however, these are considered wildcat and proprietary cartridges.
