The

700 Nitro Express (17.8×89mmR) is a big game rifle cartridge. The 700 Nitro Express cartridge is typically charged with around 250 grains of powder, in addition to a two grain igniter charge (to reduce the tendency of the cartridge to hang fire from such large powder charges).
The cartridge was introduced in 1988 by the boutique gunmakers Holland & Holland (H&H) of London, England. It was developed by Jim Bell and William Feldstein and built by H & H. Feldstein had tried unsuccessfully to get H & H to build a .600 Nitro Express for him, but they had already ceased production. However, when Bell and Feldstein produced the entirely new 700 Nitro Express , they were able to attract the interest of H & H, which was looking for a new big-bore cartridge.
