Ammunition rounds, pistol, brass case with virtually flat bullet round tip.
Description: this is an example of a special 220 grain 'domed' target bullet developed by Eley. In 1905 the Royal Navy, whose pistol team was enjoying particular success, purchased 5,000 rounds of .455 loaded with this bullet with private funds, and were so pleased with it that they proposed it be adopted as the service cartridge to replace the unsatisfactory .455 Mark II round nosed bullet. The Royal Laboratory noted that the bullet closely resembled one of its own 1900 designs, RL 10833, and re-commenced investigation of blunt or flat nosed bullets. This culminated in the adoption of the Mark IV, with a flat nosed 220 grain bullet, in May 1912. '.450 Colt' was one of the many synonyms for the .450 Adams service cartridge, and may have been introduced at the point after its introduction in 1900 when the Colt New Service Target revolver began to oust the Smith & Wesson New Model No. 3 and the Webley 'WG' Target as the preferred competition revolver at Bisley. The Colt was specially made with Metford rifling for the British market and was notably accurate. Long superceded by the .476 and the .455 as service rounds, the .450 lived on as a mild shooting very accurate target cartridge and pocket revolver round.
