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 .50 Action Express (AE) (12.7×33mmRB) is a large-caliber handgun cartridge, best known for its usage in the Desert Eagle. Developed in 1988 by American Evan Whildin of Action Arms, the .50 AE is one of the most powerful pistol cartridges in production.
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 14 years, before being replaced by the .38 Long Colt in 1892.
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 .360 Dan Wesson, .357 Magnum, .38 Special, .38 Long Colt, and .38 Short Colt rounds. 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 .480 Ruger (12.1×33mmR) is a large, high-power revolver cartridge, introduced in 2003 by Ruger and Hornady. It was the first new cartridge introduced by Ruger, and when introduced, was the largest-diameter production revolver cartridge, at .475 in (12.1 mm).
The .38 Short Colt, also known as .38 SC, was a heeled bullet cartridge intended for metallic cartridge conversions of the cap and ball Colt 1851 Navy Revolver from the American Civil War era.
The .475 Linebaugh is a rimmed revolver cartridge developed by John Linebaugh in the late 1980s in response to the scarcity of the .348 Winchester brass required to form his .500 Linebaugh cartridge. The cartridge is based on the .45-70 Government case trimmed to 1.4 inches and loaded with .475-inch-diameter (12.1 mm) bullets. While dimensionally similar to the older .45 Silhouette cartridge, the .475 Linebaugh is loaded to considerably higher pressures, resulting in significantly different ballistic performance.
A .50 caliber handgun is a handgun firing a bullet measuring approximately 0.5 inches (12.7 mm) in diameter. Historically, many black powder pistols fired bullets with diameters well above a half inch. However, following the development of smokeless powder, the focus shifted to smaller-diameter bullets propelled at higher velocities, and the development of .50 and larger calibers in handguns became uncommon.
The Ruger Blackhawk is a six-shot, single-action revolver manufactured by Sturm, Ruger & Co. It is produced in a variety of finishes, calibers, and barrel lengths.
The Magnum Research BFR is a single-action revolver manufactured by Magnum Research. Modeled after the Ruger Blackhawk, it is constructed of stainless steel and chambered for a number of powerful handgun cartridges, such as .460 S&W Magnum and .500 S&W Magnum; popular rifle chamberings, including .30-30 WCF, .444 Marlin, and .45-70 Government; and even .410 bore shotshells. Notably, the BFR platform has also served as the basis for custom caliber conversions to 19th century big game cartridges such as the .50-110 WCF and .50-90 Sharps, as well as the .500 Bushwhacker, which is currently considered to be the most powerful handgun cartridge in the world in terms of muzzle energy. The name "BFR" originally stood for “Brainerd’s First Revolver”, in reference to Brainerd, Minnesota, where the early BFRs were manufactured. Officially the acronym now stands for "Biggest, Finest Revolver", though it was rebranded for a time as the “Big Frame Revolver” after Magnum Research’s 2010 acquisition by Kahr Arms.
John Linebaugh was an American gunsmith from Cody, Wyoming, known for creating custom firearms. He was the inventor of the .500 Linebaugh (1986) and .475 Linebaugh (1988) cartridges. Gunwriter John Taffin, a big-bore enthusiast, describes Linebaugh as a "pioneer" in developing powerful sixguns.
The .500 Wyoming Express or .500 WE is a "big bore" handgun cartridge. Freedom Arms introduced the cartridge in 2005 for their Model 83 .500 WE revolver.
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 similar caliber, similar to other designations such as "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.
Freedom Arms is a Freedom, Wyoming based firearm manufacturing company, known for producing powerful single-action revolvers. The company was founded in 1978 by Wayne Baker and Dick Casull to produce the Mini revolver then later a revolver chambered in Casull's powerful .454 Casull chambering. This 5-shot revolver was the Model 83. Freedom Arms currently makes a single-shot pistol in addition to their revolvers.
The .500 Linebaugh is a .50 caliber handgun cartridge designed for use in revolvers. It is considered one of the most powerful handgun cartridges designed in terms of kinetic energy and power factor (momentum).
The .500 S&W Magnum or 12.7×41mmSR is a .50 caliber semi-rimmed revolver cartridge developed by Cor-Bon in partnership with the Smith & Wesson "X-Gun" engineering team for use in the Smith & Wesson Model 500 X-frame revolver and introduced in February 2003 at the SHOT Show. From its inception, it was intended to be the most powerful handgun cartridge to date, with the capacity to harvest all North American game species. While more powerful handgun cartridges, such as the .500 Bushwhacker, have emerged since, they are only available in custom firearms, and the .500 S&W remains the most powerful production handgun cartridge.
John August Taffin is an American author from Boise, Idaho who writes several columns for gun magazines including Guns, Gun Digest, Sixgunner, Shoot! and American Handgunner. A former math teacher from 1964-1995, Taffin is regarded as an authority on single-action revolvers, handloading, handgun hunting, big-bore revolvers, and metallic silhouette shooting. Taffin has authored five books and over 500 published articles. His monthly published gun columns include: Siluetas, Campfire Tales, The Sixgunner, and Taffin Tests.
Richard J. Casull was a Salt Lake City-born gunsmith and wildcat cartridge developer whose experiments with .45 Colt ammunition in the 1950s led to the creation of the .454 Casull cartridge. Casull's passion was six-shooters, and he was determined to create a high velocity round for the .45 Colt. His goal was to achieve a muzzle velocity of 2,000 feet per second with Colt .45 rounds fired from a single-action Army-style revolver with a 7+1⁄2inch barrel. This proved impossible due to the tensile strength of the Colt .45 cylinder, so he set out to develop his own casing and bullet.
The .41 Special—also commonly known as .41 Spl, .41 Spc, or 10.4x29mmR —is a wildcat (non-standardized) cartridge designed for revolvers, made to be a less powerful variant of the established .41 Remington Magnum. The cartridge was intended for police work and personal defense, using a 200 grain bullet at 900 feet per second. While proposed as early as 1955, it remains a niche, custom cartridge.
