History
The .700 NE was commissioned in 1988 by American hunters Jim Bell and William Feldstein, who approached Holland & Holland requesting the most powerful sporting rifle that could be made. H&H obliged. The cartridge fires a 1,000-grain bullet — heavier than many .50 BMG projectiles — at 2,000 fps from a double rifle weighing approximately 19 pounds. Holland & Holland made the first rifles; a small number of other makers have since produced examples. Fewer than 14 rifles are believed to exist. The cartridge has technically been used on elephant and cape buffalo, but its practical application is essentially academic — the .500 NE or .600 NE is considered more than sufficient for any living animal. The .700 NE exists as an engineering statement and the ultimate expression of the British double rifle tradition.
