Product Info .450 Marlin Ammo

The 450 Marlin is a firearms cartridge designed as a modernized equivalent to the .45-70 cartridge. It was designed by a joint team of Marlin and Hornady engineers headed by Hornady’s Mitch Mittelstaedt,[3] and was released in 2000, with cartridges manufactured by Hornady and rifles manufactured by Marlin, mainly the Model 1895M levergun. The Browning BLR is also now available in .450 Marlin chambering, as is the Ruger No. 1. Marlin ceased manufacture of the 1895M rifle in 2009. It is not known if or when this model will be available again.

LEVERevolution 450-Marlin represents a breakthrough in ammo design for lever action rifles and revolvers. The key to its innovation and performance is the patented elastomer Flex Tip technology of the FTX and MonoFlex bullets. Safe to use in tubular magazines, these bullets feature higher ballistic coefficients and deliver dramatically flatter trajectory for increased down range performance.

Does Hornady still make 450-Marlin ammo?

NOTE: The innovative LEVERevolution FTX and MonoFlex bullet designs may require a newer magazine follower to provide best possible functioning of the last round out of the magazine in certain guns.

While ballistically similar to the .45-70, the .450 Marlin was not developed from the .45-70. Rather, the .450 Marlin was developed from the wildcat .458×2″ American, which was based on the .458 Winchester Magnum.[4] This places the .450 Marlin in the .458 Winchester family of cartridges, though it is more easily understood as a “modernized” .45-70. It is possible to handload the .45-70 to levels that can destroy older firearms such as the Trapdoor Springfield. The .450 Marlin offers the ballistics of such hot” .45-70 loads without the risk of chambering in firearms that cannot handle its higher pressure.

The belt has been modified to prevent it from chambering in smaller-bore 7 mm Magnum or .338 Magnum rifles.[5] The .45-70 and .450 Marlin cannot be cross-chambered, but rifles chambered for the American can be modified to fire the .450 Marlin.[6]

Visually, the case resembles that of the .458 Winchester Magnum with a wider belt.[7] The cartridge is most useful for hunting big game at short ranges, being accurate at ranges of 150 to 175 yards (137 to 160 m).[4] The cartridge is capable of taking any large game animal in North America including large elk, brown bear, and moose.

One potential advantage of the .450 Marlin was its ability to chamber easily in bolt-action rifles, essentially becoming a “.45-70 bolt action” cartridge. This idea, however, was only utilized by one company: Steyr-Mannlicher. However, many companies such as E.R. Shaw Inc. and EABCO have helped numerous owners convert their existing bolt-action rifles to .450 Marlin, fulfilling the cartridge’s inspired purpose.

What are Hornady FTX bullets used for?

  • Flex Tip Technology: The patented Flex Tip technology of the FTX and MonoFlex bullets provide higher ballistic coefficients and velocity increases of up to 250 fps over traditional flat point loads while still providing shock-absorbing safety in tubular magazines.
  • Modern Propellants: New propellants provide maximum muzzle velocity at conventional pressures, resulting in flatter trajectories and more downrange energy. Exceptional accuracy and overwhelming downrange terminal performance for hornady 325 ftx bullets.
  • Overwhelming Performance: LEVERevolution ammunition outperforms conventional loads for high weight retention, delivering up to 40% more energy than traditional flat point bullets. The higher ballistic coefficients of the FTX and MonoFlex bullets produce consistently flatter trajectories than conventional bullets and provide overwhelming downrange terminal performance.
