The .400/375 Belted Nitro Express, also known as the .400/375 Holland & Holland and the .375 Velopex is a rifle cartridge designed by Holland & Holland and introduced in 1905. Development The cartridge is unique in that it was the first ever cartridge to use a belted rim. The addition of a belt to a rimless cartridge design provided the advantage of allowing for correct headspacing of highly tapered cartridges (an advantage of rimmed cartridges) and smooth feeding through magazine rifles (the advantage of rimless cartridges).Ganyana. The .400/375 Belted Nitro Express almost died at birth, as in 1905 a Berlin gunmaker, Ottoman Bock, designed the 9.3×62mm to fit into the Model 1898 Mauser bolt-action rifle, this cartridge easily eclipsed both the 9.5×57mm (1908) and the .400/375 Belted NE. In 1912 Holland & Holland created the .375 Holland & Holland Magnum utilising the same caliber in a much larger belted case, and the .400/375 Belted NE faded from production.February 2022 Kynoch still manufacture .400/375 Belted NE ammunition with a lighter loading.
