- The .32 H&R (Harrington & Richardson) Magnum is a centerfire revolver cartridge that was introduced by Harrington & Richardson in 1984. It was designed as an improvement over the .32 S&W Long cartridge, offering increased power and performance.
The .32 H&R Magnum cartridge typically fires a 85- to 95-grain bullet at a muzzle velocity of around 1,200 to 1,300 feet per second. It is capable of delivering significantly more power than the .32 S&W Long cartridge, making it suitable for use in small to medium-sized game hunting and self-defense.
The .32 H&R Magnum cartridge is a relatively low-recoil cartridge that is suitable for use in small, lightweight revolvers, and is popular among shooters who prefer a small and easily carried revolver for self-defense or as a backup gun. It is also suitable for target shooting and small game hunting. While it is not as powerful as some larger handgun cartridges, it still offers reasonable stopping power and accuracy at close range.
