32 H&R MAG

32 H&R Magnum (aka 32 Magnum) is a rimmed revolver cartridge – totally incompatible with 32 ACP semi-automatic handguns. If you have a 327 Federal Magnum revolver, then you can safely fire 32 H&R Magnum ammo. But if you only have a 32 S&W Long or 32 S&W (aka 32 S&W Short) revolver, then you have zero reason to purchase 32 H&R Magnum ammo.
