The .45 BPM is not a .460 S&W Magnum. The .45 BPM differs from the .460 S&W Magnum in several key areas. First, the .45 BPM is limited to a maximum C.O.L.

The .45 Colt originally was a black-powder cartridge, but modern loadings use smokeless powder. The original black-powder loads called for 40 grains (2.6 g) of black powder behind an Ogival & flat nosed 255-grain (16.5 g) lead bullet. These loads developed muzzle velocities of 1,050 ft/s (320 m/s).
The 14,000 psi (97 MPa) limit for .45 Colt, for example, reflects the original black powder performance of the round, and is safe even in firearms built in 1873, when the cartridge was introduced. Using modern, solid head brass in a Ruger Blackhawk revolver, a similar design originally chambered in the high pressure .41 Magnum and .44 Magnum ...
In the modern day, it is used for Black Powder Cartridge Rifle competitions. [1] While various bullet weights were used, a typical load for the .45-90 was a powder charge 90 grains (5.8 g) gunpowder (black powder) with a bullet weighing 400 grains (26 g). Such a load would have had a muzzle velocity of around 1,300 ft/s (400 m/s).
In general, loads close to 100% density (or even loads where seating the bullet in the case compresses the powder) ignite and burn more consistently than lower-density loads. In cartridges surviving from the black-powder era (examples being .45 Colt , .45-70 Government ), the case is much larger than is needed to hold the maximum charge of high ...
