Development
Development
The.500/450 Magnum BPE was created by necking down the.500 Black Powder Express to.45-inches. 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.
