One Cartridge, not a box: .340 Weatherby by Weatherby, “NEW”  production using new brass cases with “WEATHERBY 340 WBY MAG” Head-Stamp and loaded with a 250 grain JSP (Jacketed Soft Point)  projectile.

History of .340 Weatherby Cartridge:
The 340 Weatherby Magnum rifle cartridge was introduced in 1962 by creator Roy Weatherby to fill the gap between the . 300 Weatherby Magnum and the . 378 Weatherby Magnum, and in response to the . 338 Winchester Magnum released in 1958.
Weatherby announced this cartridge in 1962, and it is based on the .300 Weatherby case necked up to accept .338″ projectiles.
With Projectiles from 175 to 300 grain, this cartridge produces almost 5,000 foot-pound of energy and velocities up to 3,250  Feet per Second.
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 conducted through 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.
