The .577/500 No 2 BPE was developed as a black powder round some time before 1879 by necking down the .577 Black Powder Express to .507-inches (12.9 mm) for use in single or double rifles, as well as a variety of Martini-based lever rifles.
Like the .450 Black Powder Express, the .577/500 BPE came in several case lengths, the most common having a 3-inch case. A 3⅛-inch variant would later be loaded with cordite to become the .577/500 Nitro Express.
For some time the .577/500 No 2 BPE was loaded with cordite to become the .577/500 No 2 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.
The .577/500 No 2 BPE was a popular cartridge in India for hunting all thin-skinned game up to tiger. Like the .500 Black Powder Express, the .577/500 No 2 BPE was never popular in Africa, not being powerful enough for thick-skinned game such as elephant.
Moderately popular in its day, the round has long since ceased to be offered commercially.
