The .444 Marlin is a rifle cartridge
Cartridge (firearms)
A cartridge, also called a round, packages the bullet, gunpowder and primer into a single metallic case precisely made to fit the firing chamber of a firearm. The primer is a small charge of impact-sensitive chemical that may be located at the center of the case head or at its rim . Electrically...

 had all but disappeared from the American marketplace. There was no big-bore cartridge available in a lever-action rifle in current production, so Marlin decided to create a new cartridge to fill this empty niche. They created what is essentially an elongated version of the .44 Magnum

 by making it nearly an inch longer to give it power similar to the .45-70. The case Marlin created is very similar to a rimmed version of a .30-06 that was trimmed and necked-up to work with .429 bullets.

Hunters initially had some troubles because the .444 was frequently handloaded using existing .429 bullets that were designed for use at handgun velocities (Remington has stated in letter and email, when asked, that their 240gr .444 bullet was of a different design, and NOT the same as a .44 magnum handgun bullet). Nevertheless the rifle did gain in popularity as more suitable bullets were designed for its higher velocity.

In 1972 Marlin re-introduced the .45-70 to their lever-action line, expanding their big-bore offerings. Sales of the .444 are now overshadowed by .45-70 cartridge which has enjoyed a resurgence in popularity, due to interest in cowboy action shooting.

. It functions most efficiently when used with cast lead bullets. Hand-cast bullets allows the shooter to optimize the alloy for strength and expansion at the higher velocities generated by the Marlin over the traditional 44 caliber bullets. There are several commercial moulds available for the hand-caster: The SAEC #433 mould which casts a 300 gr gas-checked bullet, the Lyman 429640 at 280 gr are two of the more potent bullets for this caliber. Proper cartridge length is maintained by seating the bullet to the correct depth and using a crimp die to put a firm crimp on the seated bullet to prevent slippage in the magazine tube.

Best cast bullet accuracy in the .444 Marlin is attained when utilizing bullets sized to .432" diameter, both in the older "Micro-Grooved" and the newer "Ballard" style barrels. This bullet diameter is dictated more by the large diameter of chamber throats than by groove diameter of the barrel. A projectile closely fitting the throat dimensions greatly enhances the cast bullet performance of this cartridge. Those writers and publications citing the inability of the .444 Marlin's Micro-Groove barrel to accurately shoot cast bullets driven over 1600 ft/s (487.7 m/s). are simply in error, in that those results were largely obtained using .429" and .430" diameter cast bullets. Full factory velocity handloads when assembled using hard-cast, gas-checked bullets of .432" diameter will rival accuracy of any jacketed ammunition for this cartridge.

 introduced a new heavier 265 gr 0.43 inches (1.1 cm) bullet created specifically for use in this new .44 caliber cartridge. Since then Hornady has also made a 265 grain (17.2 g) interlock "Light Magnum" that boosts velocity to nearly 2350 ft/s (716.3 m/s) and 3140 ft·lbf (4,257.3 J) of energy at the muzzle. Hornady's latest offering for this caliber is its new LEVERevolution ammunition that has a soft polymer spire point that can be safely loaded in tubular magazines.

, in its 300 gr loading. A 265 gr bullet in 0.429 in (1.1 cm) has the same sectional density as a 300 gr bullet in 0.458 in (1.2 cm) and can provide good penetration on large game. According to M.L. McPherson (Editor, Cartridges of the World), "the 444 is fully capable against any species in North America." and he describes its useful range as being out to about 200 yards (182.9 m).
