Overview

The .500/450 No 1 Black Powder Express was a rimmed, bottlenecked cartridge designed for use with black powder. The cartridge was originally designed as a deer stalking round with a 260 gr (17 g) bullet, although later a 530 gr (34 g) loading was produced for target shooting.[1][2]

The .500/450 No 1 Nitro for Black was the same cartridge loaded with mild loadings of cordite, carefully balanced to replicate the ballistics of the black powder version. Unlike other similar black powder cartridges, such as the .450 Black Powder Express and .500/450 Magnum Black Powder Express, the .500/450 No 1 Express never became a Nitro Express cartridge.[2]

gollark: I'd like the option for transparent ones to remain.
gollark: Texture for WHAT?
