context_page_description: The .700 Nitro Express is a big game rifle cartridge made by Holland & Holland, London, England. It was developed in 1988 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 cartridge, they were able to attract the interest of H&H, which was looking for a new big-bore cartridge. After production began, the backlog of orders was so great that it continued to 2007 and H&H restarted the production of .600 Nitro Express guns.
context_section_description: The .700 Nitro Express develops an approximate average of 8,900 foot-pounds force (12,100 J) of muzzle energy with a 1,000 gr (65 g) bullet at 2,000 ft/s (610 m/s). However handloaders can push the cartridge to generate as much as 15,000 foot-pounds (20,000 J) of energy in a modern bolt action, by using a 1,000 gr (65 g) bullet fired at 2,600 ft/s (792 m/s). However, doing so necessitates a rifle so heavy it is almost inoperable for hunting purposes. Lathe turned cases as used in the Accurate Reloading rifle above will suffer blown primers at this level though a good source of drawn brass would allow (in theory) velocities up to 2,700 ft/s (820 m/s).
  The typical average muzzle velocity of a factory-loaded cartridge is 2,000 ft/s (610 m/s). In the 18-pound (8.2 kg) rifle used by Accurate Reloading this would result in recoil energy of approximately 160 ft⋅lbf (220 J). This is more than ten times the average recoil from a .308 Winchester which is a very common hunting calibre, and more than 4 times the recoil of a strong .45-70 Government round.
