The .444 Marlin is basically a lengthened .44 Magnum revolver cartridge. However, the .444 Marlin is far more powerful than the .44 Magnum. While the .44 Magnum is a fine brush gun, and well suited for hog hunting at moderate range, the .444 Marlin can be a true big-game rifle. The .444 hasn’t replaced the .30-30, but it has enjoyed some popularity with the lever-action crowd. The introduction of the Marlin .45-70 rifle—or reintroduction, as it may be called—cut into the .444’s popularity considerably.
