Load data for caliber ".340 Weath. Mag."
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.

C.I.P.
The Commission internationale permanente pour l'épreuve des armes à feu portatives ("Permanent International Commission for the Proof of Small Arms" – commonly abbreviated as C.I.P.) is an international organisation which sets standards for safety testing of firearms. (The word portatives ("portable") in the name refers to the fact the C.I.P. tests small arms almost exclusively; it is ordinarily omitted from the English translation of the name.) As of 2015, its members are the national governments of 14 countries, of which 11 are European Union member states. The C.I.P. safeguards that all firearms and ammunition sold to civilian purchasers in member states are safe for the users.
To achieve this, all such firearms are first proof tested at C.I.P. accredited Proof Houses. The same applies for cartridges; at regular intervals, cartridges are tested against the C.I.P. pressure specifications at the ammunition manufacturing plants and at C.I.P. accredited Proof Houses.
