Once again...you cant hardly go wrong with any of the 6.5's 6.5x55, 260, 264 etc. Good guns! Most manuals show the 260 as faster but I cant see it with the swede being larger in capacity. Must be because of the old Mausers out there in 6.5x55 not having quite the pressure limits as the new ones. Maybe its efficiency..lol..I dont really know. But either will kill deer like the Hammer of Thor
