Load data for caliber ".338 Win Mag."
The .338 Winchester Magnum is a powerful centerfire rifle cartridge designed for hunting large and dangerous game, such as elk, moose, and bear. It was introduced in 1958 by Winchester Repeating Arms Company and has since become a popular choice among hunters and long-range shooters.The .338 Winchester Magnum has a bullet diameter of .338 inches and a case length of 2.5 inches. It is capable of firing bullets weighing between 200 and 250 grains at velocities ranging from 2,700 to 2,900 feet per second, depending on the load. This results in a high muzzle energy and a flat trajectory, making it an effective choice for long-range shooting.
However, the .338 Winchester Magnum also generates a significant amount of recoil, which can make it difficult to shoot accurately for some people. It is also a relatively expensive cartridge to shoot, as the ammunition can be costly.

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.
