The .32 H&R Magnum, also known as the .32 Magnum, is a rimmed cartridge designed for use in revolvers. It was developed and introduced in 1984 as a joint venture between Harrington & Richardson and Federal Premium Ammunition.

Contents

The .32 Magnum was designed to more than double the speed and energy of the less powerful .32 Smith & Wesson Long cartridge, on which it is based. Loadings for the .32 H&R Magnum even typically exceed hot .38 Special +P loads in terms of both speed and energy. The .32 Magnum also has a higher maximum pressure than the .38 Special. [3]

Performance

The .32 H&R Magnum offers substantially more performance than most other .32 caliber handgun cartridges, such as the .32 ACP, and is considered an effective small-game hunting cartridge. When loaded to potential, the cartridge can provide similar performance from a handgun to the traditional .32-20 from a rifle. Though not always considered normative according to modern considerations, historically, this range of performance between the light and heavier expanding loads has proved efficient and versatile for many people, some of whom were evidently more than satisfied with relying on one rifle for both small game and medium-sized deer within reasonable range. Its higher velocity [4] offers a flat trajectory, while the light weight of the bullet results in low recoil.

Maximum pressure for the .32 H&R Magnum is set at 21,000 CUP by SAAMI. [5]

Use

In 2013, Hornady introduced a .32 H&R Magnum "Critical Defense" cartridge designed for self-defense. It propels an 80 gr (5.2 g) grain FTX (flex tip), bullet at 1,150 ft/s (350 m/s) muzzle velocity. [6] Buffalo Bore offers +P rated cartridges with either 100 gr (6.5 g) JHP or 130 gr (8.4 g) Keith hard cast SWC bullets. [7]

Since the .32 H&R Magnum headspaces on the rim and shares the rim dimensions and case and bullet diameters of the shorter .32 S&W and .32 S&W Long cartridges, these shorter cartridges may be safely fired in arms chambered for the .32 H&R Magnum. However, the longer, more powerful .32 H&R Magnum cartridges cannot be safely fired in arms designed for the .32 S&W or .32 S&W Long. [8]

In 2007, the .32 H&R Magnum was the basis for a "super magnum", the .327 Federal Magnum. The .32 H&R can safely be fired out of any firearm chambered for .327 Federal. [9]

Handguns

In addition to Harrington & Richardson, other manufacturers who have offered revolvers in .32 H&R Magnum include Dan Wesson Firearms, Charter Arms (professional 7 round revolver), Freedom Arms, Smith & Wesson (J and K frames), Ruger (Blackhawk, Single-Six, GP100, SP101, Ruger LCR and LCRx), Taurus, and New England Firearms (NEF). In addition, any gun chambered for the .327 Federal Magnum cartridge can fire the .32 H&R Magnum safely.

American Derringer, Bond Arms, and Cobra Firearms offer derringers in .32 H&R Magnum, while Thompson Center Arms offered their Contender pistol in it.

Rifles

Marlin offered the Model 1894CB lever-action rifle in .32 H&R Magnum. Unlike other Marlin 1894s, the 1894CB loads from the front of the tubular 10-shot magazine, like their Model 39A rimfire rifle, and has a faster, 10% shorter throw, lever action. It has a 20 in (510 mm) tapered octagonal barrel, an overall length of 37.5 in (950 mm), and weighs 6.5 lb (2.9 kg). [10]

<span class="mw-page-title-main">Rimfire ammunition</span> Type of ammunition that is only commonly found in small-caliber firearms

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.

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 .444 Marlin (10.9×57mmR) is a rifle cartridge designed in 1964 by Marlin Firearms and Remington Arms.

The .444 resembles a lengthened .44 Magnum and provides a significant increase in velocity. It is usually used in the Marlin 444 lever-action rifle. Currently, Marlin, who is now owned by Ruger Firearms, does not offer the .444 chambering in any of their rifles. It remains to be seen when or if they will bring the chambering back into production.

<span class="mw-page-title-main">Overpressure ammunition</span> Type of small arms ammunition

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.

<span class="mw-page-title-main">.327 Federal Magnum</span> US revolver cartridge

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 .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.
