The .577 BPE originated around 1870 with the 2 1 ⁄ 2-inch variant. [1]The 3-inch cartridge has survived to the current day as the .577 Nitro for Black, the same cartridge loaded with mild loadings of modern smokeless powder, carefully balanced through trial to replicate the ballistics of the Black powder version.
