Boss & Co is primarily known for shotguns, but the company has produced double rifles on special commission since the late Victorian era. A Boss Double Rifle in 470 NE is among the rarest and most unusual British dangerous-game rifles, combining Boss's perfected lock-work and action regulation with the most popular dangerous-game cartridge. Fewer than 20 Boss double rifles in any caliber are documented; when they appear at auction they generate exceptional interest. Type: Rifle Action: Double / SxS Caliber: 470 Nitro Express Capacity: 2 Year introduced: 1900, United Kingdom Weight: 186 oz Overall length: 43" Status: Active Intended use: Dangerous Game / Collector
