History
The cartridge emerged from the tradition of wildcatting the Weatherby magnum case family to produce maximum-performance cartridges in various calibers. The .460 Weatherby Magnum parent case provides enormous capacity, enabling velocities previously impossible in .375-caliber factory cartridges. As a wildcat, it requires custom reamer-cut chambers and handloaded ammunition. It has never achieved commercial standardization and remains a small-community cartridge among serious dangerous game hunters.
