Big Fifty Sharps Rifle
This was a .50 caliber Sharps rifle used by professionals for buffalo hunting. It weighed between 11 to 16 pounds unloaded.
The cartridge case for the .50-90 was 2.5-inches long and was loaded with 90 to 110 grains of black powder. The longer .50-140 case, developed after the buffalo harvest had ended, was loaded with 120 to 140 grains black powder for differing ranges.
