Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for .475 No.2 Nitro Express, so this is the shape gravity alone gives the advertised velocity. Drag would steepen it. The tool below solves real loads through their published G1 or G7 model.

History
Developed around 1907 for high-grade British double rifles by Westley Richards and other English makers, the .475 No.2 NE is distinct from the original .475 Nitro Express despite the similar name. It offers slightly different case dimensions and ballistics, and both are encountered in antique double rifles from the Edwardian period.
