The 500 NE bolt-action Big Game Rifle from John Rigby & Co is among the rarest and most powerful bolt-action sporting rifles produced by any British maker. Chambering the 500 Nitro Express in a magazine action requires a massively enlarged magazine well and action body, and the resulting rifle weighs over 12 pounds. These guns were typically ordered by elephant hunters who wanted the magazine reserve of a bolt-gun combined with the authority of a 500-caliber bullet. Type: Rifle Action: Bolt-Action Caliber: 500 Nitro Express Capacity: 3 Year introduced: 1900, United Kingdom Weight: 204 oz Overall length: 46.5" Status: Active Intended use: Dangerous Game
