 Weatherby started manufacturing Weatherby Guns in his garage at the Huntington Park home.Weatherby firearms are best known for their very high-powered rifle cartridges, all bearing the name Weatherby Magnum such as the .257 Weatherby Magnum and the .460 Weatherby Magnum, and for the production of appropriately-chambered sporting rifles.Weatherby came into the world of commercial cartridge and rifle making with a background of experimentation in cartridge wildcatting and was determined to develop a range of sporting rifle cartridges that would produce very high muzzle velocities, high bullet energies, very flat trajectories, and very hard-hitting characteristics at long range.
