The .32 H&R Magnum is a centerfire handgun cartridge developed by the American firearms manufacturer Harrington & Richardson (H&R). It was introduced in the 1970s as a higher‑pressure, longer‑case variant of the .32 S&W Long, intended to provide improved ballistic performance for revolvers and other firearms chambered for the cartridge.
Design and specifications
- Parent case: Derived from the .32 S&W Long, the case is lengthened to 1.32 in (33.5 mm) and loaded to higher pressures.
- Bullet diameter: .312 in (7.92 mm).
- Typical bullet weights: 70 gr, 78 gr, and 90 gr.
- Typical muzzle velocity: Approximately 1,050–1,300 ft/s (320–400 m/s) depending on bullet weight and load.
- Maximum pressure: Specified by standard loading data for the cartridge; exact figures are defined by manufacturers and loading manuals.
Firearms chambered for .32 H&R Magnum
The cartridge has been offered in several H&R revolvers, including the Model 900 and Model 904 series, as well as in certain single‑action revolvers and a limited number of semi‑automatic pistols. Some rifles and convertible firearms have also been chambered for the round, primarily for hunting small game and varmint control.
Performance and usage
The .32 H&R Magnum delivers higher velocity and energy than the standard .32 S&W Long, making it suitable for self‑defense, target shooting, and small‑game hunting at short to moderate ranges. Its performance is comparable to other .32‑caliber magnum cartridges, though it has not achieved the same level of commercial popularity as the .38 Special or .357 Magnum.
Historical context
H&R introduced the cartridge during a period of expanding handgun cartridge options in the United States, aiming to provide a higher‑power alternative within the .32 caliber family. Production continued while the company was active in the small‑arms market; following H&R’s cessation of firearms manufacturing, the cartridge has remained available through ammunition manufacturers and handloaders.
Current status
Although not as widely produced as more common handgun cartridges, the .32 H&R Magnum is still manufactured by several ammunition companies and supported by handloading data. Interest in the cartridge persists among collectors and shooters of vintage H&R revolvers and those seeking a moderate‑power .32 caliber round.
