.32 H&R Magnum

US rimmed revolver cartridge

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.

Quick Facts Type, Place of origin ...

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. 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]
