The .444 Marlin was introduced in 1964 as a high-powered lever-action cartridge, developed jointly by Marlin and Remington to give the lever-gun platform a genuinely large-bore, heavy-bullet option. It fires a .429-inch bullet from a rimmed, straight-walled case and has earned a reputation as a hard-hitting medium- to large-game round suited to wooded country where shots are close and penetration matters more than long-range reach. Hornady's unprimed brass cases for the .444 Marlin are produced to the same strict standards as the broader Hornady brass range — smaller production lots, tight wall concentricity, uniform case wall thickness and weight-sorting to maintain consistent internal capacity. Every case is pressure calibration tested to ensure reliable expansion during firing. For handloaders running a Marlin lever-action or similar chambering, these cases offer a dependable, repeatable platform to build accurate loads — whether you're after classic cast-bullet performance or loading one of the heavier jacketed bullets the calibre accommodates. Supplied unprimed and trimmed ready for the press.
