444 Marlin Ammo

After the .45-70 disappeared from the market in the 1960s, there was still a need for a large cartridge designed for lever-action rifles. Enter the .444 Marlin, designed by Marlin Firearms and Remington Arms in 1964. See for yourself why hunters quickly adopted this cartridge with the Steinel Ammunition collection.

While essentially a .44 Magnum elongated by an inch, the .444 Marlin cartridge delivered similar firepower to the .45-70 Government. This made it especially popular with hunters, who needed a powerful big-bore cartridge that could take down medium to large game.

Sadly, when Marlin began manufacturing .45-70 rifles and ammunition, the .444 Marlin was gradually used less and less. Marlin finally ceased production of rifles chambered in .444 Marlin in 2011, which led ammunition manufacturers to reduce production of the outdated cartridge.

Manufactured with a variety of weights and points, there’s a perfect cartridge for every lever-action shooter here. Try this classic and rare alternative caliber to the .45-70 today!
