History of ..460 Weatherby Cartridge:
The 460 Weatherby, the King of the Weatherby line was introduced in 1958. It was made by necking out the 378 Weatherby to except .460 projectiles.As the 378 Weatherby is a blown out 416 Rigby case to increase powder capacity, then necked down to except .378 projectiles, then the 460 was Wildcat cartridge of the 416 Rigby Parent Cartridge. The 460 weatherby is loaded with 300 to 500 Grain projectiles traveling at up to 2,775 feet per Second to produce up to 6,800 Foot Pounds of Energy.
History of the Weatherby cartridge line:
As a young man, in the late 1940’s, Roy Weatherby developed an insatiable interest in ballistics and rifle performance.
At a time when many firearms “experts” were promoting large bullets traveling at slow speeds, Roy was experimenting with lighter weight bullets traveling at extremely high velocities.
It was his belief that this combination was ideal in creating the hydrostatic shock needed to kill animals quickly and humanely.
In Roy’s mind, there was no other way: speed kills – period.Roy’s initial work began with developing his high powered, magnum cartridges.
He developed the .220 Rocket (based on the .220 Swift), and the first Weatherby Magnums – .257, .270 and .300 (based on the .300 H&H Mag.).
From his small operation in South Gate, California, Roy was building his own rifles on virtually any actions he could obtain (FN Mauser, Schultz & Larsen and Mathieus to name a few), as well as offering to rechamber rifles for his newly designed magnum calibers.
Soon, his high powered cartridges began to draw the attention of noted gun writers Jack O’Connor, Elmer Keith and influential such as Sheldon Coleman (of Coleman Company fame).
Over the years, Roy would have many “friendly arguments,” often conductedthrough printed letters and rebuttals in magazines, with the likes of O’Connor, Keith and other firearms experts on the merits of his high velocity cartridges and rifles.By the mid to late 1950’s Weatherby had expanded his line of magnum cartridges to include the .378 Weatherby Magnum (which replaced the .375 Weatherby Magnum) and the .460 (the world’s most powerful cartridge, at the time, delivering nearly four tons of muzzle energy).
At that time, he was producing his rifles on German FN Mauser and Czechoslovakian Brevex Magnum Mauser actions.Later, in 1957, he would develop a new action – originally designated the Model 58 (later to become the legendary Mark V) – specifically designed to handle the magnum loads of his increasingly popular cartridges.
