A revolver is a repeating handgun that has at least one barrel and uses a revolving cylinder containing multiple chambers for firing. Because most revolver models hold up to six cartridges, before needing to be reloaded, revolvers are commonly called six shooters or sixguns. Due to their rotating cylinder mechanism, they may also be called wheel guns.
The .38 Special, also commonly known as .38 S&W Special, .38 Smith & Wesson Special, .38 Spl, .38 Spc, or 9x29mmR is a rimmed, centerfire cartridge designed by Smith & Wesson.
The Colt Single Action Army is a single-action revolver handgun. It was designed for the U.S. government service revolver trials of 1872 by Colt's Patent Firearms Manufacturing Company and was adopted as the standard-issued pistol of the U.S. Army from 1873 until 1892.
The .357 SIG is a bottlenecked rimless centerfire handgun cartridge developed by the Swiss-German firearms manufacturer SIG Sauer, in cooperation with ammunition manufacturer Federal Premium. The cartridge is used by a number of law enforcement agencies.
The .357 Smith & Wesson Magnum, .357 S&W Magnum, .357 Magnum, or 9×33mmR is a smokeless powder cartridge with a 0.357 in (9.07 mm) bullet diameter. It was created by Elmer Keith, Phillip B. Sharpe, and Douglas B. Wesson of firearm manufacturers Smith & Wesson and Winchester. The .357 Magnum cartridge is notable for its highly effective terminal ballistics.
The .38 Super, also known as .38 Super Auto, .38 Super Automatic, .38 Super Automatic +P , .38 Super +P , or 9×23mmSR, is a pistol cartridge that fires a 0.356-inch-diameter (9.04 mm) bullet. It was introduced in the late 1920s as a higher pressure loading of the .38 ACP, also known as .38 Auto. The older .38 ACP cartridge propels a 130-grain (8.4 g) bullet at 1,050 ft/s (320.0 m/s), whereas the .38 Super pushes the same bullet at 1,280 ft/s (390.1 m/s). The .38 Super has gained distinction as the caliber of choice for many top practical shooting competitors; it remains one of the dominant calibers in IPSC competition.
The .454 Casull is a firearm cartridge, developed as a wildcat cartridge in 1958 by Dick Casull, Duane Marsh and Jack Fullmer. It was announced in November 1959 by Guns & Ammo magazine. The design is a lengthened and structurally improved .45 Colt case. The wildcat cartridge went mainstream when Freedom Arms brought a single action five-shot revolver chambered in .454 Casull to the retail firearms market in 1983. Ruger followed in 1997, chambering its Super Redhawk in this caliber. Taurus followed with the Raging Bull model in 1998 and the Taurus Raging Judge Magnum in 2010. The .45 Schofield and .45 Colt cartridges can fit into the .454's chambers, but not the other way around because of the lengthened case.
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 .38 Long Colt, also known as .38 LC, is a black powder cartridge introduced by Colt's Manufacturing Company in 1875. In 1892, it was adopted as a standard military pistol cartridge by the United States Army for the Colt M1892 revolver. The metric designation for the .38 Long Colt is 9.1×26mm. It is slightly more powerful than the .38 Short Colt, also known as .38 SC. The original .38 SC and .38 LC differ in case length, bullet diameter, weight, and design and are not interchangeable; however, modern production .38 SC ammunition is now loaded with a smaller, internally-lubricated bullet which can be fired from firearms chambered in .38 LC or .38 Special. The modern .38 LC can be fired from .38 Special firearm, but not from a firearm designed for the .38 SC, since the case length is too long.
The .44 Remington Magnum, also known as .44 Magnum or 10.9x33mmR, is a rimmed, large-bore cartridge originally designed for revolvers and quickly adopted for carbines and rifles. Despite the ".44" designation, guns chambered for the .44 Magnum round, its parent case, the .44 Special, and its parent case, the .44 Russian all use 0.429 in (10.9 mm) diameter bullets. The .44 Magnum is based on the .44 Special case but lengthened and loaded to higher pressures for greater velocity and energy.
The .357 Maximum, formally known as the .357 Remington Maximum or the .357 Max, is a super magnum handgun cartridge originally developed by Elgin Gates as the wildcat .357 SuperMag. The .357 Maximum was introduced into commercial production as a joint-venture by Remington Arms Company and Ruger in 1983 as a new chambering for the Ruger Blackhawk. Shortly thereafter, Dan Wesson Firearms and Thompson/Center Arms introduced firearms in this cartridge. United Sporting Arms chambered it in their Silhouette series single-action revolvers. It is a .357 Magnum case lengthened 0.300 inches (7.6 mm). Based on the .357 Magnum cartridge, a revolver or single-shot pistol designed for the .357 Remington Maximum will chamber and fire the .360 Dan Wesson, .357 Magnum, .38 Special, .38 Long Colt, and .38 Short Colt cartridges. Intended primarily as a silhouette cartridge, such high velocity and energy levels have hunting applications. SAAMI pressure level for this cartridge is set at 40,000 pounds per square inch (280 MPa).
The .38 S&W, also commonly known as .38 S&W Short, 9×20mmR, .38 Colt NP , or .38/200, is a revolver cartridge developed by Smith & Wesson in 1877. Versions of the cartridge were the standard revolver cartridges of the British military from 1922 to 1963. Though similar in name, it is not interchangeable with the later .38 Special due to a different case shape and slightly larger bullet diameter.
The .32 S&W Long, also known as 7.65x23mm, is a straight-walled, centerfire, rimmed handgun cartridge, based on the earlier .32 S&W cartridge. It was introduced in 1896 for Smith & Wesson's first-model Hand Ejector revolver. Colt called it the .32 Colt New Police in revolvers it made chambered for the cartridge.
.455 Webley is a British handgun cartridge, most commonly used in the Webley top break revolvers Marks I through VI. It is also known as ".455 Eley" and ".455 Colt".
The .41 Long Colt cartridge was created in 1877 for Colt's double-action "Thunderer" revolver.
Overpressure ammunition, commonly designated as +P or +P+, is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber, but less than the pressures generated by a proof round. This is done typically to produce ammunition with higher muzzle velocity, muzzle energy, and stopping power, such as ammunition used for security, defensive, or hunting purposes. Because of this, +P ammunition is typically found in handgun calibers which might be used for paramilitary forces, armed security, and defensive purposes.
A super magnum is a longer and/or more powerful version of a "magnum" cartridge. Although the term "super magnum" typically refers to a handgun cartridge, created by lengthening an existing straight-case design, it can also refer to rifle and shotgun cartridges, such as the .17 Winchester Super Magnum and the 31⁄2" 12 Gauge Super Magnum. In this case, it simply denotes that it is of greater power than existing "magnums" of a similar caliber or gauge, this is comparable to other designations, such as the "Remington Ultra Magnum". The most widespread of these cartridges are the "SuperMag" family of super-magnum handgun cartridges that were proposed and tested by Elgin Gates in the 1970s.
The .327 Federal Magnum is a cartridge introduced by Federal Premium Ammunition and also sold by Sturm, Ruger & Co. It is intended to provide the power of a .357 Magnum in six-shot, compact revolvers, whose cylinders would otherwise only hold five rounds. The .327 has also been used in full-sized revolvers with a capacity of seven rounds or more. The .327 Federal Mag is an example of a "super magnum", because it is a magnum of a magnum, the .32 H&R Magnum.
The Colt Walker, sometimes known as the Walker Colt, is a single-action revolver with a revolving cylinder holding six charges of black powder behind six bullets. It was designed in 1846 by American firearms inventor Samuel Colt to the specifications of Captain Samuel Hamilton Walker.
