Overview of 44-40 Winchester Ammo
44-40 Winchester, also called 44 WCF (Winchester Center Fire), is one of the most famous cartridges of the American frontier. It fires a .427-inch lead bullet, usually 200 to 225 grains, at around 750 to 1,200 fps. Today it is a favorite of cowboy action shooters and owners of reproduction Winchester 1873 and 1892 lever guns and Colt Single Action Army revolvers.
Modern 44-40 ammunition is loaded to low pressures that are safe in both original-design and reproduction firearms. It is not interchangeable with .44 Special or .44 Magnum.

Frequently Asked Questions
Is 44-40 the same as .44 Special or .44 Magnum?
No. 44-40 Winchester uses a bottlenecked case and a .427-inch bullet, while .44 Special and .44 Magnum use straight-walled cases and .429-inch bullets. They are not interchangeable.
Is modern 44-40 ammo safe in old guns?
Modern factory 44-40 is loaded to low pressures, but any antique firearm should be checked by a qualified gunsmith before firing. Black powder-era guns in particular may not be safe with smokeless ammunition.
Why is 44-40 popular for cowboy action shooting?
44-40 was the original chambering of the Winchester 1873 and a common chambering in the Colt Single Action Army, so it fits the history of the sport. Its mild recoil and lead flat nose loads also work well on steel targets at cowboy action distances.
More About 44-40 Winchester Ammo
Winchester introduced 44-40 in 1873 as the chambering for its Model 1873 rifle, often called "the gun that won the West." Colt soon chambered its Single Action Army revolver for the same cartridge, so frontier settlers, ranchers, and lawmen could carry one type of ammunition for both rifle and handgun.
The 44-40 went on to become one of the best-selling cartridges of the late 1800s and stayed in production through the 20th century. Today it lives on through reproduction lever guns and revolvers and the growing sport of cowboy action shooting.
