In 1873, Winchester introduced the gun that would be known as “The Gun that Won the West”—the Winchester 1873 lever action rifle, chambered in .44 WCF (Winchester Center Fire.) The same year, Colt introduced the 1873 Colt SAA revolver in Colt .45 and the US Army introduced the .45-70 Government.
Colt, realizing that western settlers wouldn’t want to carry different types of ammunition for their rifles and side arms, decided to chamber their 1873 SAA revolvers in .44 WCF—though they renamed the .44 WCF to .44-40 (.44 caliber and 40 gains of black powder) in order to prevent giving Winchester free advertising.
Winchester never reciprocated by chambering any of its guns in Colt .45.
Today, most lever gun reproductions are chambered in the Colt .45 for two reasons. First, the rims on modern Colt .45s are stronger than their 19th Century counterparts; and second, .44-40 Winchester ammunition is rather scarce.
If you have considered buying or reloading the .44-40 Win, here are some helpful recommendations from my experience.
The Colt 45 also known as 45 Long Colt, 45 LC is one of the original center fire cartridge still in production and going strong.
The 45 Colt came in to being when the US Army put out for bid a new revolver that would use a 45 caliber bullet at 250 grains over 40 grains of black powder. It is said the requirement was based on the desire to have a revolver that could drop an Indian War pony at 100 yards.
Colt beat out Smith and Wesson with their now famous Colt 1873 Single Action Army revolver and the cartridge got it’s first name the Colt 45. However good the revolver was difficult to reload on horse back. The Army then ordered some break open design pistols from Smith & Wesson known as the Schofield revolver. These guns proved to be very popular and successful however they were not strong enough to fire a full power Colt 45 cartridge. They were chambered in basically a shortened version of the Colt 45.
Now that the Army had two 45 caliber revolver cartridges in inventory and they both could be fired in the 1873 SAA revolver, the name 45 Long Colt started to be used to avoid confusing with the Schofield cartridge. It is a fun cartridge to shoot and reload but caution must be used when reloading because with many smokeless powder there is a danger of double or triple charging a case. That’s why we recommend using Tin Star powder.
Try using Tin Star powder for your Colt .45. This powder will fill the case completely like black powder but it is a smokeless powder that has a light bulky density for use in old black powder cartridges like the Colt 45 and give you the pressure and velocity as the originals. Most people shoot the Colt 45 in Cowboy type guns like the 1873 SAA Colt revolvers or reproductions. I would strongly advise to stay with loading cast lead bullets. The original lead alloy for these bullets was 20 parts lead and one part Tin. This alloy will give you the best performance and the least leading problem.
Quality Cowboy bullets are made by Missouri Bullets. A charge of Tin Star powder that nearly reaches the bottom of a 250 grain Missouri Bullet from a 7 1/2″ barrel will give you a velocity of 930 FPS. LG Outdoors has a good supply of this hard to find reloading powder..
Reloading is the process of loading casings or shells by putting together the components of the cartridge yourself. It is sometimes referred to as hand loading.
Economy, increased accuracy, performance, commercial ammunition shortages, and hobby interests are all common motivations for hand loading both cartridges and shot shells. Reloading fired cartridge cases will save the shooter money. Continue reading RELOADING MANUALS AND INFORMATION→
