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.
The 7.62 mm caliber is a nominal caliber used for a number of different cartridges. Historically, this class of cartridge was commonly known as .30 caliber, the equivalent in Imperial and United States Customary measures. It is most commonly used in hunting cartridges. The measurement equals 0.30 inches or three decimal lines, written .3″ and read as three-line.
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile, a propellant substance and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile.
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.
A semi-automatic pistol is a handgun that automatically ejects and loads cartridges in its chamber after every shot fired. Only one round of ammunition is fired each time the trigger is pulled, as the pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset.
A 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 Desert Eagle is a gas-operated, semi-automatic pistol known for chambering the .50 Action Express, the largest centerfire cartridge of any magazine-fed, self-loading pistol.
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 19 years, before being replaced by the .38 Long Colt in 1892.
The .256 Winchester Magnum is a firearms cartridge developed by Winchester, and was produced by necking-down a .357 Magnum cartridge to .257 diameter. It was designed for shooting small game and varmints.
The .45 Winchester Magnum is a .45 caliber rimless cartridge intended for use in semi-automatic pistols. The cartridge is externally a lengthened .45 ACP with a thicker web to withstand higher operating pressures. The 45 Win Mag is nearly identical in dimensions and loading to the .45 NAACO developed by the North American Arms Corporation for their Brigadier pistol, developed to supply to the Canadian Army after World War II. The army ultimately did not adopt the pistol and its non-NATO standard ammunition.
The .22 Winchester Magnum Rimfire, also called .22 WMR, .22 Magnum, .22 WMRF, .22 MRF, or .22 Mag, is a rimfire cartridge. Originally loaded with a bullet weight of 40 grains (2.6 g) delivering velocities in the 2,000 feet per second (610 m/s) range from a rifle barrel, .22 WMR is now loaded with bullet weights ranging from 50 grains (3.2 g) at 1,530 feet per second (470 m/s) to 30 grains (1.9 g) at 2,200 feet per second (670 m/s).
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge.
The .44 Auto Mag pistol (AMP) is a large caliber semi-automatic pistol. It was designed between 1966 and 1971 by the Auto Mag Corporation to make a semi-automatic pistol chambered in .44 AMP.
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, was offered that year as the United States' first small-bore sporting rifle cartridges designed for smokeless powder. Since its introduction, it has been utilized alongside the development of flatter shooting cartridges, most prominently those derived from designs subsidized by interest in military expenditures, yet the .30-30 has remained in widespread use almost entirely because of reliable effectiveness in civilian applications, proven by putting food on the table for millions of people within a practical range of hunting situations.
The .475 Wildey Magnum is a large semi-automatic pistol cartridge designed for big game hunting in the Wildey pistol.
The Marlin Model 336 is a lever-action rifle and carbine made by Marlin Firearms. Since its introduction in 1948, it has been offered in a number of different calibers and barrel lengths, but is commonly chambered in .30-30 Winchester or .35 Remington, using a 20- or 24-inch barrel. Currently, the model with a 24-inch barrel is only available in .30-30 Winchester. The Model 336 is now back in production as of March 27, 2023.
The Grizzly Win Mag pistols were conceived, invented, designed, engineered and developed in the 1980s by the sole inventor, Perry Arnett, who licensed his patent for an interchangeable caliber semi-automatic pistol to L.A.R. Manufacturing Inc. Perry Arnett's designs were initially flawed and were improved upon by Heinz Augat. The L.A.R. Grizzly was the most powerful semi-automatic pistol ever commercially produced after the Desert Eagle.
The .45 Super is a powerful smokeless powder center fire metallic firearm cartridge developed in 1988 by Dean Grennell, a well-known writer in the firearms field as well as managing editor of Gun World magazine. It is dimensionally similar to the .45 ACP round but has a thicker case wall and is loaded to higher pressures, which offers an average 300 feet per second (91 m/s) improvement in muzzle velocity over the .45 ACP. The cartridge was co-developed by Tom Fergerson and Ace Hindman.
Robert Hillberg was a firearm designer and the head of Research & Development at the High Standard Manufacturing Company. His designs included the folding shotgun stock, the Whitney Wolverine lightweight pistol, Wildey .45 gas-operated pistol, COP .357 Derringer pistol, and M60 machine gun. Hillberg developed a variety of insurgency weapons, primarily multiple barrel shotguns, which could be covertly distributed to partisan forces fighting in the United States' national interests. Gun Digest editors have described Hillberg as a "national treasure."
