Sharps

The .50-140 Sharps and the .50-140 Express are nearly identical cartridges. The primary differences are the weight of the bullets used. The .50140 Sharps was produced as a special order item and was usually used with a 700 grain paper patched lead bullet which could be purchased commercially for loading the cartridge.

This was the most powerful of the Sharps (Buffalo) cartridges, but by the time it became available, the buffalo herds had already been destroyed.

Currently available as a special order from manufacturers of Sharps replicas, the .50-140 Sharps is strictly a handloader's proposition. Eldorado Cartridge Company still offers excellent quality cartridge cases for this round.

The pressure limit set for this cartridge by Accurate was developed by firing a 140 grain charge of FFg black powder and a 550 grain lead bullet. This produced a pressure of28,000 PSI.

The .50-140 Sharps is a powerful cartridge capable, with smokeless propellant, of driving a 550 grain cast bullet the same velocity as the factory 500 grain bullet from a .458 Winchester Magnum.

This data is intended only for firearms safe for use with smokeless propellants.
