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 was produced by lengthening the .32 S&W Long case by .155", to 1.075".

[edit] Performance
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 offers a flat trajectory, while the light weight of the bullets results in low recoil.
One of the .32 H&R magnums 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.
The .32 H&R Magnum is considered by many to be at the lower end of acceptable self-defense cartridges, comparing favorably with the popular .380 ACP and with standard-pressure .38 Special loads, as well as the less powerful .32 ACP.
Max pressure for the .32 H&R Mag is set at 21,000 CUP by SAAMI.[3]
