It is similar to, though larger than, the .50-90 Sharps. SpecificationsBullet diameter is typically {{convert|.512|in|abbr=on}}, with weights of {{convert|600|to|700|gr}}. The powder charge is typically {{convert|140|gr}} of black powder. Modern substitutes such as Pyrodex are sometimes used, although using smaller charges since pyrodex is less dense than black powder.[4] In a strong action with modern smokeless powder, it can exceed a {{convert|500|gr|sing=on}} .458 Winchester Magnum velocity while using a heavier {{convert|550|gr|sing=on}} bullet.[6] HistoryThe .50-140 was created for big game hunting, and was the most powerful of the Sharps Bison cartridges.[5] However, it was introduced about the time of the end of the great Bison herds.[6] An obsolete round, ammunition is not produced by any major manufacturer although reloading components and brass can be acquired or home-built. Rifles are infrequently produced by a few companies. They are typically used for bison hunting and reenactments. Occasionally, the .50-140 is used in vintage competitions, although some shooters claim it produces heavier recoil than other old-time cartridges such as the .45-70. See also
