Product Overview 450 marlin
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, 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.
The Marlin M1895 in .45-70, released in 1972 has without a doubt been a major success. Nevertheless, the full potential of this combination has only been possible through hand loading. This is due to the fact that factory produced .45-70 ammunition is loaded to low pressures and velocities for older firearms. In an effort to create a more powerful off the shelf combination for factory ammunition users, the companies Marlin and Hornady set about creating a new and more powerful factory cartridge.
One design that had already served as a successful wildcat was the 2” version of the .458 Winchester Magnum, normally featuring a 2.5” case. The design premise was sound however Marlin and Hornady did not wish to adopt this exact design as the 2” .458 posed a risk in that it could easily be chambered in another 2.5” magnum chamber- including .375 H&H chambers. To overcome this problem, Mitch Mittelstaedt of Hornady designed the new case with a longer belt at the case head.
In the year 2000, Marlin and Hornady introduced the new .450 Marlin. The initial factory load featured the 350 grain Hornady Flat point Interlock at 2100fps from the full length 24” barreled Marlin rifle, a significant boost in energy over the traditional .45-70 factory loads. While this combination could have been immensely successful, the high cost of factory ammunition resulted in relatively poor market acceptance. As a hand loading proposition, the .450 Marlin had slightly less powder capacity than the .45-70 due to the heavy case walls so again, sales have been limited.
Presently, the .450 Marlin enjoys limited popularity, mostly enjoyed by staunch fans of Marlin lever action rifles. To some extent is a pity that Marlin were not able to create a cartridge as powerful as the .458 Winchester Magnum. Regardless of appeal, ultimately, it is very difficult to produce an affordable cartridge if it utilizes a large quantity of expensive raw materials as all big bore cartridges do.
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.
The .450 Marlin is a versatile short to medium range cartridge, ideal for light through to large medium game and adequate for large heavy game with due consideration.
When used on light to medium weight game, the .450 loaded with a 300 grain hollow point projectile may produce hydrostatic shock down to impact velocities of around 2100fps, though I have witnessed nervous trauma at lower speeds. With or without shock, internal wounds are extremely broad down to impact velocities of 1700fps, resulting in extremely fast kills.
New propellants provide maximum muzzle velocity at conventional pressures, resulting in flatter trajectories and more downrange energy. Exceptional accuracy and overwhelming downrange terminal 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.
Hornady produce two loads for the .450 Marlin, the lightest being the 325 grain FTX Leverevolution bullet at an advertised 2225fps in 24” barrels giving on average 2100fps in 24” barreled rifles and around 1800fps in the stubby 18.5” barreled guide gun. This is purely a light to medium weight game bullet although several hunters have used it on relatively large game. The FTX bullet is incredibly devastating at very close ranges. But as velocity falls away, this bullet tends to be a mild performer and shows no advantage over traditional designs. The BC of the FTX bullet is no better than other .354 caliber flat nose projectiles and penetration must be regarded as poor at very close ranges with performance increasing as ranges are extended.
Hornady’s heaviest load is the 350 grain flat point Interlock at a true 2100fps in 24” barrels and 1800fps in the guide gun. This Hornady bullet is a good allrounder for use on light through to large medium game. It is a fast killer and gives deep penetration along with a useful effective fast killing range. Unfortunately, on large heavy animals, the 350 grain Interlock is prone to suffer jacket core separation and or excessive weight loss. Even on quartering away shots, the Hornady bullet cannot handle the deflective angle of wide flat ribs resulting in severe bullet upset. Hornady do not make a heavy game load and it is doubtful whether they ever will, just as it is doubtful that any other major manufacturer will adopt the marlin .450 into their product lines.
