Bullet diameter is typically.512 in, with weights of 600 to. The powder charge is typically 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. In a strong action with modern smokeless powder, it can exceed a 500 gr.458 Winchester Magnum velocity while using a heavier 550 gr bullet.

The.50-140 was created for big game hunting, and was the most powerful of the Sharps Bison cartridges. However, it was introduced about the time of the end of the great Bison herds. 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.
