The Buffalo Bore Ammunition 8C20 Lever Gun Strictly Business is a .45-70 Government cartridge loaded with a 350 grain semi-jacketed flat point projectile intended for modern strong-action lever and single-shot rifles. Externally it matches SAAMI-spec .45-70 dimensions but is internally loaded to generate substantially higher pressure and energy than standard .45-70 commercial loads.
