 Curiously, Kynoch lists loads for the 9.5mm Mannlicher–Schoenauer with a 45 grain charge of smokeless propellant (for a muzzle velocity of 2200 fps) and the ".375 Rimless Nitro Express" with a reduced 43 grain charge (for a muzzle velocity of 2100 fps).This may have reflected the differences in the regulation of the sights by the respective manufacturers and distributors, between Westley Richards for the higher powered Mannlicher–Schoenauer loading and the trade rifles with the generic .375 Rimless Nitro Express loading.Cartridge cases are available from specialist dealers in obsolete cartridges.
