The .404 Rimless Nitro Express cartridge, also known as the .404 Jeffery, is a centerfire rifle cartridge that was developed by W.J. Jeffery & Co. in the early 1900s. It is a popular big game cartridge that is primarily used for hunting large, dangerous game in Africa.The .404 Rimless Nitro Express cartridge features a rimless brass case with a bullet diameter of .423 inches (10.74 mm) and a case length of 2.90 inches (73.66 mm). It typically uses a 400- to 450-grain (26 to 29 g) bullet propelled by a smokeless powder charge, which gives it a muzzle velocity of around 2,200 to 2,400 feet per second (670 to 730 meters per second) and a muzzle energy of around 4,500 to 5,000 foot-pounds (6,100 to 6,800 joules).
The .404 Jeffery cartridge was designed to provide hunters with a cartridge that had similar ballistics to the .416 Rigby cartridge, but with a smaller and lighter package that could be used in a variety of firearms, including bolt-action rifles and double rifles. It is a popular cartridge for hunting large game such as elephant, buffalo, and lion.
Today, the .404 Jeffery cartridge is considered to be a classic big game cartridge and is still used by hunters and shooters around the world. It is also a popular cartridge for African hunting safaris.

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.
