The .45 BPM can be handloaded using a .460 S&W Magnum brass casing, a standard large pistol primer, from 40 grains black powder with filler as necessary to avoid air gaps on up to 60 grains black powder. A typical bullet would consist of soft lead from 150 to 250 grains in weight with a black powder appropriate lubricant in the groove(s).
A magnum cartridge is a firearm cartridge with a larger case size than, or derived from, a similar cartridge of the same projectile caliber and case shoulder shape. [ clarification needed ] The term derives from the .357 Magnum , the original revolver cartridge with this designation.
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).
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).

A reduced-power load of 55 grains (3.6 g) of powder (Carbine Load) was manufactured for carbine use with a muzzle velocity of 1,150 feet per second (350 m/s). [4] In 1884, the US Ordnance Department increased the bullet weight of the 45–70 to 45–70–500, or a 45 caliber bullet, 70 grains of black powder, and a 500 grain bullet. [3]
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 ...
The .500/450 Magnum BPE was created by necking down the .500 Black Powder Express to .45-inches. [2]For some time after the turn of the century, the .500/450 Magnum BPE was loaded with cordite to become the .500/450 Magnum Nitro for Black, the same cartridge loaded with mild loadings of cordite, carefully balanced through trial to replicate the ballistics of the Black powder version.
