Premium .444 Marlin Brass – New & Once-Fired Rifle Casings

Reload your .444 Marlin brass with confidence when you choose Diamond K Brass, the trusted source for top-quality rifle brass casings. We proudly offer once-fired and new .444 Marlin brass that’s hand-inspected, tumble-polished, and ready for your next reloading session.

The Legacy of .444 Marlin Rifle Brass

Introduced by Marlin Firearms in the 1960s, the .444 Marlin was designed to give the classic Levergun 336 an impressive horsepower boost. Decades later, it remains a favorite among hunters and reloaders—especially as state hunting laws increasingly favor straight-wall cartridges for deer and large game.

At Diamond K Brass, we’re proud to keep that legacy alive with high-quality once-fired and new .444 Marlin brass, available in convenient packs of 50 or 100.
