The .32 H&R Magnum is a centerfire cartridge designed for revolvers, introduced in 1984. It is a longer and more powerful version of the .32 S&W Long cartridge, providing increased velocity and energy. This makes it suitable for target shooting and small game hunting. The .32 H&R Magnum typically features a bullet diameter of .312 inches and is available in various bullet weights, usually ranging from 85 to 100 grains. Its moderate recoil and accuracy make it popular among shooters who prefer a lighter caliber for self-defense and recreational shooting.
