The .44 Remington Magnum, also known as .44 Magnum or 10.9x33mmR (as it is known in unofficial metric designation), 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 the .44 Special's parent case, the .44 Russian all use 0.429 in (10.9 mm) diameter bullets. [3] The .44 Magnum is based on the .44 Special case but lengthened and loaded to higher pressures for greater velocity and energy.
Famously called "the most powerful handgun [cartridge] in the world" by Clint Eastwood in Dirty Harry , the .44 Magnum has since been eclipsed in power by the .45 Winchester Magnum, .454 Casull, .460 S&W Magnum, .475 Wildey Magnum, .480 Ruger, .50 Action Express, .500 S&W Magnum, and the .500 Bushwhacker; nevertheless, due in part to its more manageable recoil, it has remained one of the most popular commercial large-bore magnum cartridges. [4] [5]
The .44 Magnum cartridge was the result of years of tuned handloading of the .44 Special. [6] In the early 20th century, experimenters loaded the .44 Special and other large-bore handgun cartridges with heavy bullets and higher than normal powder charges to achieve superior ballistics and better hunting performance. One of these hand-loaders was Elmer Keith, a prominent writer and outdoorsman of the 20th century. [7]
Keith settled on the .44 Special cartridge as the basis for his experimentation, rather than the larger .45 Colt. At the time, the selection of .44 caliber projectiles for hand-loaders was more varied, and the .44 Special's brass was thicker and stronger than the dated .45 Colt case. Also, the .44 Special case was smaller in diameter than the .45 Colt case. In revolvers of the same cylinder size, this meant that the .44 caliber revolvers had thicker, and thus stronger, cylinder walls than the .45. This allowed higher pressures to be used with less risk of a cylinder failure. [4]
Keith and his associates successfully lobbied Smith & Wesson and Remington to produce a commercial version of this new high-pressure loading, along with revolvers chambered for it. Smith & Wesson's first .44 Magnum revolver, the precursor to the Model 29, was built on December 15, 1955, and the gun was announced to the public on January 19, 1956 [8] for a price of US$140 (roughly $1,600 today). [9] Julian Hatcher (technical editor of American Rifleman ) and Keith received two of the first production models. Hatcher's review of the new Smith & Wesson revolver and the .44 Magnum cartridge appeared in the March 1956 issue of the magazine. Smith & Wesson produced 3,100 of these revolvers in 1956. [10]
By the summer of 1956, Sturm, Ruger became aware of this project and began work on a single action Blackhawk revolver for the new .44 Magnum cartridge. There is a popular rumor that a Ruger employee found a cartridge case marked ".44 Remington Magnum" and took it to Bill Ruger, while another says a Remington employee provided Ruger with early samples of the ammunition. [11] Ruger began shipping their new revolver in late November 1956.
The .44 Magnum case is slightly longer than the .44 Special case. This alteration was not primarily intended to increase the propellant capacity of the cartridge, but rather to prevent the far higher pressure round from being chambered in older, weaker .44 Special firearms and potentially causing injury or death to shooters. [4]
The .44 Magnum was an immediate commercial success. The direct descendants of the S&W Model 29 and the .44 Magnum Ruger Blackhawks are still in production, and have been joined by numerous other makes and models of .44 Magnum revolvers and even a handful of semi-automatic models, the first being produced in the 1960s. [12] The film Dirty Harry , prominently featuring the S&W M29 shooting .44 Special ammo, contributed to that model's popularity. [13]
Ruger introduced its first long gun, a semi-automatic carbine called the Ruger Model 44 chambered for .44 Magnum, in 1959. Marlin followed soon after with the lever action Model 1894 in .44 Magnum. [5] [7] Having a carbine and a handgun chambered in the same caliber is an old tradition; the .44-40 Winchester was introduced by Winchester in a lever action in 1873, and Colt followed in 1878 with a revolver in the same caliber. The .38-40 Winchester and .32-20 Winchester were also available in both carbines and revolvers, allowing the shooter to use one type of ammunition for both firearms. [14]
Although improved modern alloys and manufacturing techniques have allowed even stronger cylinders to be made, leading to larger and more powerful cartridges such as the .454 Casull and .480 Ruger in revolvers the same size as a .44 Magnum, the .44 Magnum is still considered an exceptional weapon. [15] In 2006, to commemorate the 50th anniversary of the .44 Magnum, Ruger introduced a special 50th anniversary Blackhawk revolver, in the "Flattop" style. [11]
The .44 Magnum fires a large, heavy bullet at a high velocity for a handgun. In its full-powered form, it produces so much recoil and muzzle blast that it is generally considered to be unsuitable for use as a police weapon. Rapid fire is difficult and strenuous on the user's hands, especially for shooters of smaller build. [16] [17]
Although marketed as a .44 caliber, the .44 Magnum and its parent .44 Special are actually .429-.430 caliber. The .44 designation is a carryover from the early measurements of heeled bullets used in the late 19th century. In those times, bullet diameter typically matched the external dimension of its respective cartridge, not the interior of the round. After the .44 Russian was developed, the forefather of the .44 Special and thus the .44 Magnum, the measurement of bullet caliber was taken from inside of the cartridge, resulting in .429 caliber.
Some gun styles are more comfortable to use when shooting this caliber. Many shooters find the rounded grip shape of the single action better for handling heavy recoil than the grip shape of double-action revolvers, which have a shoulder on top of the grip. Many shooters consider the ideal type of grip for heavy recoiling guns to be the longer "Bisley" style single action grip, and it can be found on single actions from Ruger (models marked "Bisley") and Freedom Arms, as well as many custom makers. [18]
The concept of a dual-purpose handgun/rifle cartridge has been popular since the Old West, with cartridges like the .44-40 Winchester, whose "high-speed" rifle loadings were precursors to magnum loads. Other dual-use rounds were the .32-20 Winchester and the .38-40 Winchester. [5] [14]
Some past dual-purpose cartridges, like the .44-40 Winchester, gave their manufacturers trouble when people loaded the "high-speed" versions designed for rifles into handguns. [5] Since the .44 Magnum was designed from the start as a revolver cartridge, there are no such issues, and SAAMI-compliant ammunition fires from any handguns or rifles chambered for the .44 Magnum.
For a handgun cartridge, the bolt thrust is considerable at C.I.P. conform maximum loads and an important factor in weapons design. The greater the bolt thrust, the stronger the locking mechanism has to be to withstand it.
As a rifle or carbine cartridge, the .44 Magnum is sufficiently powerful for medium-sized game, yet fits easily into a compact, lightweight package. In 1961, Ruger introduced their .44 carbine, the first .44 Magnum carbine. The lever-action Marlin Model 1894, and many other firearms are currently available in this caliber. With significantly longer barrels than revolvers and no cylinder gap (except in revolving rifles), carbines will generate a significantly higher velocity than a revolver loaded with the same ammunition. [19] Tests with various ammunition in the Ruger Deerfield yielded a 100 yd (91 m) velocity of over 1,300 ft/s (400 m/s) with a 240-grain (16 g) bullet, comparable to the muzzle velocity out of a revolver. [20] [21] Loads using slow-burning powders maximize performance in both short and long barrels, with one published load generating 1,500 ft/s (460 m/s) from a revolver, and 1,625 ft/s (495 m/s) from a carbine with a 240-grain (16 g) bullet.
The .44 Magnum is well suited for game up to elk size. With precise shot placement and deep-penetrating cartridges, it has even been used to take the largest of game, including Cape Buffalo. Publisher Robert E. Petersen took a record-setting polar bear with a Smith & Wesson Model 29 .44 Magnum. [7] [22] It has even been used against elephants with success. [23]
In addition to beating the ballistics of the old .44-40 rifle loads, long considered a top deer cartridge, [5] the heavy, flat-point bullets typically used in the .44 Magnum have an additional advantage. Tests performed where bullets are shot through light cover, intended to represent twigs and brush, have shown that the high-velocity, lightweight, thin-jacketed, pointed bullets used by most hunting cartridges today are easily deflected by contact with the brush. The ideal bullets for penetrating brush with minimal deflection are heavy, flat-point bullets at moderate velocities. [20]
The accuracy of the .44 Magnum is very good, with models from Colt, Smith & Wesson, and Ruger producing bullet groups of 3 to 4 inches (7.6 to 10.2 centimetres) at 50 yards (46 m), with most ammunition. [24] [25] The limiting factor of the .44 Magnum cartridge is not terminal ballistics. When fired from a 6 in (152 mm) revolver, a typically loaded .44 Magnum 240 gr (16 g) bullet will have more impact energy at 150 yd (137 m) than a 246 gr (15.9 g) .44 Special has at the muzzle, when fired from the same weapon. [26] When loaded with a heavy, non-expanding bullet, the .44 Magnum will easily shoot through large game such as elk and even bison. [27]
The limiting factor is the bullet's trajectory: the best hunting bullets are heavy, so they are relatively slow. This means the projectile's trajectory will drop significantly at ranges beyond 100 yards (91 m); there will be virtually zero significant drop at 50 yd (46 m), so the gun's aimed "line of sight" can meet the "bullet's trajectory" at the same point. When drop-out at 100 yd (91 m) is about 2 inches (5.1 centimetres), the drop-out at 150 yards (137 m) is more than 8 inches (20 centimetres); with a 100 yd (91 m) zero drop-out, the drop-out at 150 yd (137 m) will still measure more than 6 inches (15 centimetres). [28] Experts limit hunting ranges to 100 yards (91 m) when shooting .44 Magnum cartridges, less if practical accuracy requires it. [20] [29]
The .44 Magnum remained mildly popular among shooters for many years after its introduction, but did not come to the attention of the general public until 1971 when it was prominently featured in the American feature film Dirty Harry starring Clint Eastwood. [30] In one of the classic lines in cinema, title character "Dirty" Harry Callahan describes his Smith & Wesson Model 29 as "the most powerful handgun in the world". Although the more powerful .454 Casull wildcat cartridge was announced in 1959, [5] the .44 Magnum was the most powerful production cartridge until the 1980s when the first production .454 Casull revolver was produced. [31] The .44 Magnum was also bought and used by the character Travis Bickle in the 1976 film Taxi Driver during his assault on a brothel. The Taxi Driver soundtrack by Bernard Herrmann also features a song titled "The .44 Magnum is a Monster".
Demand for the Model 29 increased so much that they were selling for up to three times the suggested retail price. When the Model 29 could not be obtained, customers sought other handguns chambered in this caliber, such as the Ruger Redhawk. [32]
The .38 Special, also commonly known as .38 S&W Special, .38 Smith & Wesson Special, .38 Spl, .38 Spc, or 9×29mmR is a rimmed, centerfire cartridge designed by Smith & Wesson.
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 .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), often called the .45 Long Colt, 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. Although there has never been a ".45 Short Colt" cartridge, the .45 Colt is frequently called the ".45 Long Colt" to better distinguish it from the shorter and less powerful .45 Schofield cartridge, which was also in use around the same time as the .45 Colt.
The .44 Smith & Wesson Special, also commonly known as .44 S&W Special, .44 Special, .44 Spl, .44 Spc, or 10.9×29mmR, is a smokeless powder center fire metallic revolver cartridge developed by Smith & Wesson in 1907 as the standard chambering for their New Century revolver, introduced in 1908.
The .41 Remington Magnum, also known as .41 Magnum or 10.4×33mmR, is a center fire firearms cartridge primarily developed for use in large-frame revolvers, introduced in 1964 by the Remington Arms Company, intended for hunting and law enforcement purposes.
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 .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 .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).
A wildcat cartridge, often shortened to wildcat, is a custom-made cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created as experimental variants to optimize a certain ballistic performance characteristic of an existing commercial cartridge, or may merely be intended as novelty items.
The .460 S&W Magnum round is a powerful revolver cartridge designed for long-range handgun hunting in the Smith & Wesson Model 460 revolver.
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.
Elmer Merrifield Keith was an American rancher, firearms enthusiast, and author. Keith was instrumental in the development of the first magnum revolver cartridge, the .357 Magnum (1935), as well as the later .44 Magnum (1956) and .41 Magnum (1964) cartridges, credited by Roy G. Jinks as "the father of big bore handgunning." Keith was born in Hardin, Missouri, and overcame serious injuries that he had sustained at age 12 in a fire when he was living in Missoula, Montana.
The Super Redhawk is a line of double-action magnum revolvers made by Sturm, Ruger beginning in 1987, when Ruger started making weapons using larger, more powerful cartridges such as .44 Magnum, .454 Casull, and .480 Ruger.
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.
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 revolver cartridge. This 5-shot revolver was the Model 83. Freedom Arms currently makes a single-shot pistol in addition to their revolvers.
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.
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.
