In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger, hammer/firing pin or frizzen, and therefore do not need a sizable receiver behind the barrel to accommodate a moving action, making them far less complex and more robust than revolvers or magazine/belt-fed firearms, but also with much slower rates of fire.
In firearms terminology, an action is the functional mechanism of a breech-loading firearm that handles the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the lock.
John Moses Browning was an American firearm designer who developed many varieties of military and civilian firearms, cartridges, and gun mechanisms – many of which are still in use around the world. He made his first firearm at age 13 in his father's gun shop and was awarded the first of his 128 firearm patents on October 7, 1879, at the age of 24. He is regarded as one of the most successful firearms designers of the 19th and 20th centuries and pioneered the development of modern repeating, semi-automatic, and automatic firearms.
A semi-automatic firearm, also called a self-loading or autoloading firearm, is a repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber (self-loading) and prepares it for subsequent firing, but requires the shooter to manually actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, each trigger pull only discharges a single round from a semi-automatic weapon, as opposed to a fully automatic weapon, which will shoot continuously as long as the ammunition is replete and the trigger is kept depressed.
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, or automatic/selective-fire actions. A firearm using this operating mechanism is colloquially referred to as a levergun.

Known as the "King of the .22s," the Model 52 Sporter was ranked by Field & Stream as one of "the 50 best guns ever made" and described by Winchester historian Herbert Houze as "perfection in design." However, by the 1970s the World War I-era design was showing its age and had given way in top-level competition to newer match rifles from Walther and Anschütz; the costly-to-produce Model 52, which had long been a loss leader prestige product by that time, was finally discontinued when US Repeating Arms took over the manufacture of Winchester rifles from Olin Corporation in 1980.

The bolt is a controlled-round feed design and utilizes dual locking lugs on the front. The rifle also has an automatic safety that is engaged each time the bolt is cycled, so any time a round is loaded the safety is on and has to be manually turned off before the rifle is ready to fire.
