The .45-70 Government cartridge, commonly known as the .45-70, is a centerfire rifle cartridge that was introduced by the U.S. Army in 1873 for use in the Springfield Model 1873 "Trapdoor" rifle. It was originally designed for use in military service, but it has since gained popularity among civilian hunters and shooters as well.The .45-70 cartridge has a bullet diameter of .458 inches (11.6 mm) and a case length of 2.105 inches (53.4 mm). It is typically loaded with bullets weighing between 300 and 500 grains (19.4 to 32.4 g), and has a typical muzzle velocity of around 1,200 to 1,800 feet per second (370 to 550 m/s) and a muzzle energy of around 1,600 to 2,500 foot-pounds (2,200 to 3,400 J).
The .45-70 is a versatile cartridge that can be used for hunting a wide variety of game, including deer, elk, and bear. It is also commonly used for long-range target shooting and cowboy action shooting competitions. Because it is a relatively low-pressure cartridge, it can be used in both modern rifles and older, antique firearms such as the original Springfield Model 1873 "Trapdoor" rifle.
Overall, the .45-70 is a powerful and versatile cartridge that has a long and storied history. It continues to be popular among hunters and shooters who appreciate its power, accuracy, and versatility.

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.
