The .45-75 WinchesterCentennial is a centerfire rifle cartridge developed in 1876 for the newly designed Winchester Model 1876 Centennial lever-action rifle. Winchester Repeating Arms Company introduced the rifle and cartridge at the United States Centennial Exposition. The Model 1876 rifle used an enlarged version of the famous Winchester Model 1873 action to offer a lever-action repeating rifle using cartridges suitable for big-game hunting. The cartridge and rifle enjoyed brief popularity with Gilded Age American hunters including Theodore Roosevelt, and was issued to the Canadian North-West Mounted Police and to Texas Rangers. [4]

Nomenclature of the era indicated the .45-75 cartridge contained a 0.45-inch (11 mm) diameter bullet with 75 grains (4.9 g) of gunpowder. Early Winchester ammunition boxes suggested reloading empty cartridge cases with government musket powder or with American Powder Company Deadshot Fg, Hazard Powder Company Sea Shooting Fg, DuPont Rifle FFg, Oriental Powder Company Western Sporting Fg, Laflin & Rand Orange Rifle Fg, or Austin Powder Company Rifle Powder FFg. Boxes also recommended casting bullets from an alloy of one part tin and sixteen parts lead and lubricating bullets with Japan wax or tallow. [5]

The .45-75 was shorter and fatter than the .45-70 government cartridge. Although the .45-75 was nominally superior to the popular .45-70, the weak toggle-link action with its elevator-style carrier originally designed for handgun cartridges limited the ability of the Model 1876 rifle to safely fire higher pressure loads intended for stronger actions. Within a decade, the Model 1876's advantage of faster loading for subsequent shots was eclipsed by the stronger and smoother Winchester Model 1886 action capable of handling longer cartridges, including the .45-70 with varying lengths for 300 and 500 grain bullets. [4]

The Kennedy lever-action rifle manufactured by Whitney Arms Company was also chambered for the .45-75. The .45-75 and similarly short .40-60 Winchester, .45-60 Winchester, and .50-95 Winchester Express cartridges designed for the Model 1876 rifle faded into obsolescence as 20th-century hunters preferred more powerful smokeless powder loadings of longer cartridges designed for stronger rifles. Winchester production of .45-75 cartridges ended during the Great Depression. [2]

Winchester rifle is a comprehensive term describing a series of lever action repeating rifles manufactured by the Winchester Repeating Arms Company. Developed from the 1860 Henry rifle, Winchester rifles were among the earliest repeaters. The Model 1873 was particularly successful, being marketed by the manufacturer as "The Gun That Won the West".

<span class="mw-page-title-main">Lever action</span> Type of firearm action

Lever action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, fully automatic, and/or burst mode actions. A firearm using this operating mechanism is colloquially referred to as a levergun.

The .45 Colt (11.43×33mmR), is a rimmed, straight-walled, handgun cartridge dating to 1872. It was originally a black-powder revolver round developed for the Colt Single Action Army revolver. This cartridge was adopted by the U.S. Army in 1873 and served as an official US military handgun cartridge for 14 years, before being replaced by the .38 Long Colt in 1892.

<span class="mw-page-title-main">.32-20 Winchester</span> American rimmed rifle/pistol cartridge

The .32-20 Winchester, also known as .32 WCF , was the first small-game lever-action cartridge that Winchester produced. It was initially introduced as a black-powder cartridge in 1882 for small-game, varmint hunting, and deer. Colt produced a single-action revolver chambered for this cartridge a few years later.

<span class="mw-page-title-main">.44-40 Winchester</span> American firearms cartridge

The .44-40 Winchester, also known as .44 Winchester, .44 WCF, and .44 Largo, was introduced in 1873 by the Winchester Repeating Arms Company. It was the first metallic centerfire cartridge manufactured by Winchester, and was promoted as the standard chambering for the new Winchester Model 1873 rifle. As both a rifle and a handgun caliber, the cartridge soon became widely popular, so much so that the Winchester Model 1873 rifle became known as "The gun that won the West."

The Winchester Repeating Arms Company was a prominent American manufacturer of repeating firearms and ammunition. The firm was established in 1866 by Oliver Winchester and was located in New Haven, Connecticut. The firm went into receivership in 1931 and was bought by the Western Cartridge Company, a forerunner of the Olin Corporation. The Winchester brand name is still owned by the Olin Corporation, which makes ammunition under that name. The Winchester name is also used under license for firearms produced by two subsidiaries of the Herstal Group – FN Herstal of Belgium and the Browning Arms Company of Ogden, Utah.

<span class="mw-page-title-main">.30-40 Krag</span> First cartridge adopted by the US Army that was designed for smokeless powder.

The .30-40 Krag was a cartridge developed in the early 1890s to provide the U.S. armed forces with a smokeless powder cartridge suited for use with modern small-bore repeating rifles to be selected in the 1892 small arm trials. Since the cartridge it was replacing was the .45-70 Government, the new cartridge was considered small-bore at the time. The rifle ultimately selected for use by the Army was the Krag–Jørgensen, formally adopted as the M1892 Springfield. The cartridge was also used in the M1893, M1895, M1897, and M1900 Gatling guns.

<span class="mw-page-title-main">.45-70</span> Rifle cartridge designed by the U.S. Army

The .45-70, also known as the .45-70 Government, .45-70 Springfield, and .45-2110" Sharps, is a .45 caliber rifle cartridge originally holding 70 grains of black powder that was developed at the U.S. Army's Springfield Armory for use in the Springfield Model 1873. It was a replacement for the stop-gap .50-70 Government cartridge, which had been adopted in 1866, one year after the end of the American Civil War, and is known by collectors as the "Trapdoor Springfield".

<span class="mw-page-title-main">.30-30 Winchester</span> Rifle cartridge designed by the Winchester Repeating Arms Company

The .30-30 Winchester cartridge was first marketed for the Winchester Model 1894 lever-action rifle in 1895. The .30-30, as it is most commonly known, along with the .25-35 Winchester were offered that year as the United States' first small-bore sporting rifle cartridges designed for smokeless powder. Since its introduction, it has been surpassed by many cartridges in the long-range shooting attributes of speed, energy, and trajectory, yet remains in widespread use because of its practical effectiveness in forested hunting situations.

The Winchester Model 71 was a lever-action rifle introduced in 1935 and discontinued in 1958.

<span class="mw-page-title-main">.444 Marlin</span> Rifle cartridge

The .444 Marlin (10.9×57mmR) is a rifle cartridge designed in 1964 by Marlin Firearms and Remington Arms. It was designed to fill in a gap left by the older .45-70 when that cartridge was not available in any new lever-action rifles; at the time it was the largest lever-action cartridge available. The .444 resembles a lengthened .44 Magnum and provides a significant increase in velocity. It is usually used in the Marlin 444 lever-action rifle. Currently, Marlin, who is now owned by Ruger Firearms, does not offer the .444 chambering in any of their rifles. It remains to be seen when or if they will bring the chambering back into production.

<span class="mw-page-title-main">.25-20 Winchester</span>

The .25-20 Winchester, or WCF, was developed around 1895 for the Winchester Model 1892 lever action rifle. It was based on necking down the .32-20 Winchester. In the early 20th century, it was a popular small game and varmint round, developing around 1,460 ft/s with 86-grain bullets. But two years earlier Marlin Firearms Co. had already necked down the .32-20 Winchester, and called it the .25-20 Marlin. It was first chambered in Model 1889 lever action Marlins long before Winchester did the same thing and put their name on the .25-20.

The .250-3000 Savage is a rifle cartridge created by Charles Newton in 1915. It was designed to be used in the Savage Model 99 hammerless lever action rifle. The name comes from its original manufacturer, Savage Arms, and the fact that the original load achieved a 3,000 ft/s (910 m/s) velocity with an 87 grain bullet.

The .33 Winchester Center Fire is a centerfire rifle cartridge designed and produced from 1902 to 1940 by Winchester Repeating Arms Company for their Model 1886 lever-action rifle.

The Winchester Model 1886 was a lever-action repeating rifle designed by John Browning to handle some of the more powerful cartridges of the period. Originally chambered in .45-70 Government, .45-90 Sharps, and .40-82 Winchester, it was later offered in a half dozen other large cartridges, including the .50-110 Winchester. Despite being originally designed for use with black powder, the action was strong enough to make the jump to smokeless powder with only minor modifications, and was subsequently chambered in the smokeless .33 Winchester cartridge beginning in 1903.
