A curious question. Has any one here ever actually seen a 6 bore Double rifle ? I have , to date only seen two 6 bore rifles : One was WW Greener's one of a kind 6 bore Cartridge Double rifle which Currently resides in Zimbabwe. The other was an old 6 Bore Muzzleloading rifle which fired a belted ball. If anyone has ever had any experience with ( or even seen ) any 6 bore double rifles , please do enlighten me. They can ( and probably will ) be muzzleloaders or cartridge guns . Thank you all.
