Firearms designer and cartridge pioneer Charles Newton, often colloquially referred to as the "Father of High Velocity", was the first to build a hunting cartridge and rifle capable of firing a bullet at over . Weatherby was able to develop their rifles following this new trend in the design of high-velocity hunting calibers. In the late 1980s, Remington's Ultra Mag series of unbelted magnum cartridges - returning to the Newton-style of cartridge design - provided Weatherby with new competition. However, Weatherby still makes the most powerful commercially available hunting cartridge in the world with its .460 Weatherby.
