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.[2] 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 other .32 caliber handgun cartridges, such as the .32 ACP, and can be considered an effective small game hunting cartridge. Its higher velocity[3] offers a flat trajectory, while the light weight of the bullets results in low recoil. The older .32-20 Winchester was extremely popular in the Winchester lever's and Colt single actions, available at the turn of the century, for small-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 6 cartridges, whereas a similarly sized revolver in .38 special would only hold 5 rounds. Penetration is also increased compared to the .38 special with bullets of the same weight.
Max pressure for the .32 H&R Mag is set at 21,000 CUP by SAAMI.[4]
The .327 Federal Magnum is based on the .32 H&R Magnum and improves performance to levels near that of the .357 Magnum.
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.
Many handgun hunters use the .22 Winchester rimfire magnum with great success in hunting small to small-medium game, up to coyote in size. The .32 H&R magum 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.
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 fired in arms chambered for the .32 H&R Magnum. Longer cartridges are unsafe in short chambers, so more powerful .32 H&R Magnum cartridges should never be loaded into arms designed for the .32 S&W or .32 S&W Long.[5]
