The .450 Rigby, also known as the .450 Nitro Express 3 1/4", is a centerfire rifle cartridge developed in the early 20th century for hunting big game in Africa and India. It was designed to provide a powerful and reliable cartridge that could take down large and dangerous animals such as elephants and Cape buffalo.

The .450 Rigby cartridge has a bullet diameter of .458 inches (11.6 mm) and a case length of 3.25 inches (83 mm). It is typically loaded with bullets weighing between 480 and 500 grains (31.1 to 32.4 g), and has a typical muzzle velocity of around 2,150 to 2,250 feet per second (655 to 686 m/s) and a muzzle energy of around 4,400 to 4,800 foot-pounds (5,970 to 6,510 J).

The .450 Rigby cartridge is primarily used for hunting large and dangerous game in Africa and India. It is also used for some competitive shooting events.

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.
