The .32 H&R Magnum is a rimmed cartridge designed for use in revolvers. It was developed in 1984 as a joint venture between Harrington & Richardson and Federal Cartridge. The .32 H&R Magnum is produced by lengthening the .32 S&W Long case by .155", to 1.075".
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 offers a flat trajectory, while the light weight of the bullet results in low recoil. The older .32-20 Winchester was extremely popular in the Winchester lever- and Colt single-actions, available at the turn of the century, for small-to-medium game hunting. The .32 H&R offers near duplicate performance.
One of the .32 H&R Magnum's favorable attributes is that it offers .38 Special energy levels and allows a small-frame revolver to hold six cartridges, whereas a similarly sized revolver in .38 Special holds only five rounds. Penetration is also usually increased compared to the .38 Special with bullets of the same weight due to greater sectional density.
Though the .32 H&R was not designed with a particular task in mind, it is fairly well suited to small game hunting. It is also an acceptable self-defense cartridge. It is not generally considered a good "plinking" cartridge, due to high cost and poor availability of ammunition, but reloading can mitigate those issues.
Many handgun hunters use the .22 Winchester rimfire magnum with great success in hunting small to small-medium game, up to coyote-size. The .32 H&R Magnum offers increased stopping power due to its heavier bullets and larger caliber, with the added bonus that the .32 H&R magnum can be reloaded for cost savings.
In 2013, Hornady introduced a .32 H&R Magnum "Critical Defense" cartridge designed for self-defense. It propels an 80 grain FTX (flex tip), bullet at 1,150 fps muzzle velocity. Buffalo Bore offers +P rated cartridges with either a 100 gr. JHP or a 130 gr. Keith hard case SWC bullets.
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 can not be safely fired in arms designed for the .32 S&W or .32 S&W Long.

In addition to Harrington & Richardson, other manufacturers who have offered revolvers in .32 H&R Magnum include Dan Wesson Firearms, Charter Arms, Freedom Arms, Smith & Wesson (J and K frames), Ruger (Blackhawk, Single-Six, GP100, SP101, Ruger LCR and LCRx), and Taurus and New England Firearms (NEF).
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" tapered octagonal barrel, an overall length of 37.5" and weighs 6.5 lbs.
