From Wikipedia, the free encyclopedia

The .450 Marlin is a firearms cartridge designed as a modernized
                                                                                                        .450 Marlin
equivalent to the venerable .45-70 lever-action cartridge. It was
designed by a joint team of Marlin and Hornady engineers headed by
Hornady's Mitch Mittelstaedt, [4] 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. Marlin ceased manufacture
of the 1895M rifle in 2009. It is not known if or when this model will
be available again.

Design
While ballistically similar to the .45-70, the .450 Marlin was not
developed from the .45-70. Rather, the .450 Marlin was developed
                                                                                    .450 Marlin, left and .458 Winchester Magnum, right
from the wildcat .458x2 American, which was based on the .458
Winchester Magnum.[5] This places the .450 Marlin in the .458                Type                                     Rifle
