  • The .340 Weatherby Magnum is a rifle cartridge developed by Roy Weatherby in 1963. It was designed as a high-velocity, flat-shooting cartridge that would offer the power and accuracy needed for hunting and long-range shooting.

    The cartridge is based on a modified .300 Weatherby Magnum case, which was necked up to accept .338 caliber bullets. The resulting cartridge has a bullet diameter of .338 inches and a case length of 2.825 inches.

    The .340 Weatherby Magnum is capable of firing bullets weighing between 200 and 300 grains at muzzle velocities ranging from 2,850 to 3,250 feet per second. It is a powerful cartridge that is suitable for hunting a wide range of game animals, including elk, moose, and brown bear, at long ranges.

    One of the main advantages of the .340 Weatherby Magnum is its long-range accuracy, which makes it popular among long-range shooters and hunters. It is also known for its flat trajectory, which makes it easier to shoot accurately over long distances.

    The .340 Weatherby Magnum has gained a following among hunters and shooters who appreciate its combination of power, accuracy, and long-range capabilities. It is typically chambered in bolt-action rifles, and a number of firearms manufacturers produce rifles that are chambered for the .340 Weatherby Magnum cartridge.

    While the .340 Weatherby Magnum is not as widely available as some of the more established cartridges on the market, it has a dedicated following and is available from a number of firearms manufacturers. It is also relatively expensive compared to some of the more common cartridges, due to its specialized design.
