Earlier models were listed as .44 caliber, later as .45, but all use a .457" round ball or .454" conical lead bullet. [3] The Ruger Old Army can also shoot modern smokeless cartridges in .45 Colt (.45 Long Colt), or .45 ACP loaded for "cowboy action" muzzle velocities less than about 850 feet per second, via use of a drop-in conversion cylinder ...
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).
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).
Where RS (Rifle/Shotgun) is equivalent to FFg black powder and P (Pistol) is equivalent to FFFg black powder on the Fg (coarsest) to FFFFg (finest) granularity scale. While Pyrodex offers improved safety and increased efficiency (in terms of shots per pound of powder) over black powder, the level of fouling is similar to black powder as Pyrodex ...
Black powder cartridge refers to firearms ammunition from the period after the introduction of metallic cartridge, but prior to the wide adoption of smokeless powder.These cartridges (frequently but not always single-shot) had adopted the new technology of complete cartridges including a brass casing which held the powder charge, bullet, and primer.

The different cartridge must be smaller in some dimensions than the original design cartridge, and since smaller cartridges are usually cheaper, the device allows ...

[1] The P14-45 (later 14.45) is the standard model, and as its name hints, it is chambered in .45 ACP and has a magazine capacity of 14.
