The .50-140 Sharps (13×83mmR), also known as the .50-3{{frac|1|4}}" Sharps, is a black-powder rifle cartridge that was introduced in 1884, as a big game hunting round. It is believed to have been introduced for the Sharps-Borchardt Model 1878 rifle.{{cite book|last=Walter|first=John|title=The Guns that Won the West: Firearms on the American Frontier, 1848-1898|year=2006|publisher=Greenhill Books|isbn=978-1-85367-692-5|page=264}} The cartridge is very similar to the .500 Black Powder Express.{{cite book|last=Wieland|first=Terry|title=Dangerous-Game Rifles|year=2006|publisher=Countrysport Press|isbn=978-0-89272-691-2|page=283}}

This round was introduced by Winchester 3 years after the Sharps Rifle Company closed its doors in 1881. It is similar to, though larger than, the .50-90 Sharps.

With the Sharps Rifle Co. officially closing in 1881, and with the .50-140 being introduced 3 years later, the .50-140, will not be classified as Sharp's most powerful rifle cartridge.

Specifications

Bullet 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.{{cite book|last=Fadala|first=Sam|title=The Complete Blackpowder Handbook|edition=5th|year=2006|publisher=Gun Digest Books|isbn=978-0-89689-390-0|page=203|quote=Second, Pyrodex provides more shorts per pound than blackpowder because it is less dense.}} 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.

History

The .50-140 was created for big game hunting, and was the most powerful of the Sharps Bison cartridges.{{cite web|title=.50-140 Sharps|url=http://www.accuratepowder.com/data/PerCaliber2Guide/Rifle/ObsoleteCartridges/50%20140%20Sharps%20pages%20371%20and%20372.pdf|work=Accurate Powder|publisher=Western Powders Inc.|accessdate=23 September 2010|archive-url=https://web.archive.org/web/20040205082038/http://accuratepowder.com/data/PerCaliber2Guide/Rifle/ObsoleteCartridges/50%20140%20Sharps%20pages%20371%20and%20372.pdf#|archive-date=2004-02-05|url-status=dead}} However, it was introduced about the time of the end of the great Bison herds.{{cite web|last=Hawks |first=Chuck |title=Bison Cartridges of the American Frontier |url=http://www.chuckhawks.com/buffalo_cartridges.htm |work=ChuckHawks.com |accessdate=23 September 2010 |archiveurl=https://web.archive.org/web/20101010065634/http://www.chuckhawks.com/buffalo_cartridges.htm |archivedate=10 October 2010 |url-status=live }} 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.
