A rim-fire is a type of metallic cartridge used in firearms where the primer is located within a hollow circumferential rim protruding from the base of its casing. When fired, the gun's firing pin will strike and crush the rim against the edge of the barrel breech, sparking the primer compound within the rim, and in turn ignite the propellant within the case. Invented in 1845 by Louis-Nicolas Flobert, the first rimfire metallic cartridge was the .22 BB Cap cartridge, which consisted of a percussion cap with a bullet attached to the top. While many other different cartridge priming methods have been tried since the early 19th century, such as teat-fire and pinfire, only small caliber rimfire cartridges have survived to the present day with regular use. The .22 Long Rifle rimfire cartridge, introduced in 1887, is by far the most common ammunition found in the world today in terms of units manufactured and sold.
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.
A shotgun cartridge, shotshell, or shell is a type of rimmed, cylindrical (straight-walled) ammunition used specifically in shotguns. It is typically loaded with numerous small, spherical sub-projectiles called shot. Shotguns typically use a smoothbore barrel with a tapered constriction at the muzzle to regulate the extent of scattering.
The .410 bore (10.4 mm) is one of the smallest caliber of shotgun shell commonly available. A .410 bore shotgun loaded with shot shells is well suited for small game hunting and pest control. The .410 started off in the United Kingdom as a garden gun along with the .360 and the No. 3 bore (9 mm) rimfire, No. 2 bore (7 mm) rimfire, and No. 1 bore (6 mm) rimfire. .410 shells have similar base dimensions to the .45 Colt cartridge, allowing many single-shot firearms, as well as derringers and revolvers chambered in that caliber, to fire .410 shot shells without any modifications.
The .22 Winchester Magnum Rimfire, also known as the .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).
The gauge of a firearm is a unit of measurement used to express the inner diameter of the barrel.

Snake shot, rat shot, or dust shot, more formally known as shotshell or canister shot, refers to handgun and rifle cartridges loaded with lead shot canisters instead of bullets, intended for pest control. The main targets for such ammunition are snakes, rodents, birds, and other pests at very close range.
A combination gun is a firearm that usually comprises at least one rifled barrel and one smoothbore barrel, that is typically used with shot or some type of shotgun slug. Most have been break-action guns, although there have been other designs as well. Combination guns using one rifled and one smoothbore barrel are commonly found in an over-and-under configuration, while the side-by-side configuration is usually referred to as a cape gun. A combination gun with more than two barrels is called a drilling with three barrels, a vierling with four barrels, and a fünfling with five barrels. Combination guns generally use rimmed cartridges, as rimless cartridges are usually more difficult to extract from a break-action firearm.
An antique firearm is a term used to describe a firearm that was designed and manufactured prior to the beginning of the 20th century. Although the exact definition of what constitutes an "antique firearm" varies between countries, the advent of smokeless powder or the start of the Boer War are often used as cut-off dates. Antique firearms are usually collected because of their historical interest and/or their monetary value.
The M6 Aircrew Survival Weapon was a specially-made .22 Hornet over .410 bore combination gun issued to United States Air Force aircrews to help forage for food in the event of a plane crash. It was issued from 1952 until the early 1970s, in conjunction with the M4 Survival Rifle. Plans to replace both with the ArmaLite AR-5 never came to fruition and in 2018 was instead replaced with the GAU-5A Aircrew Self Defense Weapon in some instances.

Louis-Nicolas Flobert (1819–1894) was a French inventor. He invented the first metallic rimfire cartridge in 1845. It was a major innovation in firearms ammunition technology, as it was previously delivered as separate bullets and gunpowder, pertaining to muzzle-loading firearms. The rimfire cartridge combined both elements in a single metallic cartridge containing a percussion cap, gunpowder, and a bullet, into a single weatherproofed package or container. Before that, a "cartridge" was simply a pre-measured quantity of gunpowder together with a ball (bullet), in a small cloth bag, which also acted as wadding for the powder charge and ball.
