Load data for caliber ".444 Marlin"
The .444 Marlin is a centerfire rifle cartridge developed by Marlin Firearms in the mid-1960s. It was designed to be a big-bore cartridge for use in their lever-action rifles, particularly the Marlin Model 444.

The .444 Marlin has a bullet diameter of .429 inches (10.9 mm) and a case length of 2.225 inches (56.5 mm). It is a powerful cartridge capable of taking down large game at close to medium range distances, with a muzzle velocity of around 2400 feet per second (730 m/s) and a muzzle energy of around 3400 foot-pounds (4600 J).

The .444 Marlin was well-received by hunters and shooters when it was first introduced, and it remains a popular choice for hunting big game like deer, elk, and bear at close ranges. It has also been used in some single-shot and bolt-action rifles chambered for the cartridge.

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.
