444 MARLIN AMMO Superformance ammunition is loaded with proprietary propellants that increase the velocity ratings up to 200 feet per second compared to other popular brands. Because there is no increase in pressure, regardless of the caliber, there is no increase in felt recoil but there IS an increase in efficiency and high speed performance.

Hornady makes a large variety of what might be considered “conventional” bullets. These soft point bullets benefit from the same quality manufacturing techniques as Hornady’s premium bullets and will consistently perform at a level well above conventional.

The .444 Marlin can push a 240-grain (16 g) bullet at velocities over 2,400 ft/s (730 m/s) generating 3,070 ft⋅lbf (4,160 J) of energy. SAAMI has rated this cartridge at 44,000 CUP. It functions efficiently when used with cast lead bullets. Hand-cast bullets allow 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 molds available for the hand-caster: the SAEC No. 433 mold, which casts a 300-grain (19 g) gas-checked bullet, and the Lyman 429640 at 280 grains (18 g) 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.
