About .460 Weath. Mag.
The .460 Weatherby Magnum, introduced in 1959 by Roy Weatherby, was designed to provide superior performance for big game hunting. As a powerful belted magnum cartridge, it was developed to push large bullets at high velocities, making it suitable for serious hunting in diverse environments. Its inception followed the demand for an effective cartridge capable of delivering flat trajectories and substantial energy, offering shooters an edge in challenging conditions.
With a case length of 2.5 inches and a bullet diameter of 0.458 inches, the .460 Weatherby Magnum is known for its larger capacity, allowing for impressive powder charges. This enhances its ability to achieve muzzle velocities exceeding 2,800 feet per second with suitable bullet weights. Typical bullet weights for this caliber range from 300 grains to 500 grains, offering versatility in performance.
Practical applications primarily include big game hunting for species such as African elephants, cape buffalo, and other large animals. Its high energy transfer upon impact makes it an ideal choice for dangerous game situations. For reloaders, the .460 Weatherby Magnum offers significant advantages due to its wide selection of bullet types and powder options, enabling customization for various hunting scenarios and personal shooting preferences. Its relatively low recoil, in comparison to other similarly powerful magnums, also makes it more manageable for extended shooting sessions.
