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".
In 1848, Walter Hunt of New York patented his "Volition Repeating Rifle" incorporating a tubular magazine, which was operated by two levers and complex linkages. The Hunt rifle fired what he called the "Rocket Ball", an early form of caseless ammunition in which the powder charge was contained in the bullet's hollow base. Hunt's design was fragile and unworkable, but in 1849, Lewis Jennings purchased the Hunt patents and developed a functioning, if still complex rifle. This version was produced in small numbers by Robbins & Lawrence of Windsor, Vermont until 1852.
Horace Smith and Daniel Wesson of Norwich, Connecticut, acquired the Jennings patent from Robbins & Lawrence, as well as shop foreman Benjamin Tyler Henry. Smith made several improvements to the Jennings design, and in 1855 Smith and Wesson together with several investors formed a corporation, the Volcanic Repeating Arms Company, to manufacture Smith's modification of the Hunt-Jennings, the Volcanic lever-action pistol and rifle. Its largest stockholder was Oliver Winchester.
For the Volcanic rifle, Smith added a primer charge to Hunt's "Rocket Ball" and thus created one of the first fixed metallic cartridges which incorporated bullet, primer and powder in one self-contained unit. While still with the company Smith went a step further and added a cylindrical copper case to hold the bullet and powder with the primer in the case rim, thus creating one of the most significant inventions in firearms history, the metallic rimfire cartridge. Smith's cartridge, the .22 Short, would be introduced commercially in 1857 with the landmark Smith & Wesson Model 1 revolver and is still manufactured today.
