Editing Single-shot (section)

===Other single-shot actions===
*'''The [[Ferguson rifle]]''': British Major Patrick Ferguson designed his rifle, considered to be the first military breechloader, in the 1770s.  A plug-shaped breechblock was screw-threaded so that rotating the handle underneath would lower and raise it for loading with ball and powder; the flintlock action still required conventional priming.
*'''The [[Hall rifle]]''': The United States' first breechloading cavalry carbine, the Hall was introduced in 1819. The lever tipped the breechblock including the chamber upwards and back, allowing it to be loaded with powder and ball without the inconvenience of loading and ramming from the muzzle.  Originally flintlocks, Halls later were made as or converted to percussion locks.
*'''The [[Kammerlader]]''':  A crank-operated Norwegian firearm produced around the time of the Prussian Needle-gun. Originally used a paper cartridge. Later many were converted to rimfire.
*'''The [[Burnside carbine]]''': Invented by future-general [[Ambrose Burnside]] in 1857, this percussion-cap carbine became the third-most common cavalry breechloader in the Civil War after the Sharps and Spencer.  Essentially a modification of the Hall concept, the Burnside featured a unique conical cartridge with a crushable hollow front rim, designed to seal the breech on closing.
*'''The [[Rising breech carbine]]''': An unusual action produced by Bilharz, Hall and Co. for the southern [[Confederate States of America|Confederacy]], the rising breech's underlever caused the breechblock including the chamber to slide vertically above the line of the barrel, the reverse of a falling-block; the chamber was loaded from the front with a paper cartridge.
*'''The Morse Carbine''': Its action is similar to the Hall rifle but the shape of its chamber is different.
*'''Winchester Model 55''':<ref>The model number 55 was used twice by Winchester; this article refers to the .22-caliber rifle introduced in 1957, not the [[Winchester Model 1894|Model 94]] variant introduced in 1924.</ref> An unconventional hybrid of a single-shot and a [[semi-automatic firearm|semi-automatic]], this .22-caliber rifle ejected the fired case and recocked itself like a conventional [[Blowback (firearms)#Simple blowback|blowback-operated]] self-loader, but it lacked a [[Magazine (firearms)|magazine]] and had to be manually reloaded for each shot.
*"'Screw Barrel Actions'":
The OSS stinger pen pistol and several other clandestine pen guns, as well as homemade zip guns often made using plumbing parts, and cane guns used for both defense and poaching use a screw thread to attach the chambered barrel to a receiver with some sort of breech and firing pin. The user unscrews the barrel from the receiver to expose the chamber to load a cartridge. The RN50 .50 BMG single-shot rifle uses a similar screwthread breech cap to allow an otherwise simple break-action to contain a [[.50 BMG]] cartridge{{citation needed|date=January 2017}}.
