.32 Mag (.32 Harrington & Richardson Magnum) Handgun Cartridges

This cartridge was the result of a joint project between Harrington & Richardson and Federal Cartridge Company. It was introduced in 1984 for the five-shot H&R Model 504, 532 and 586 revolvers. The cartridge is simply the older 32 Smith & Wesson Long case lengthened by 0.155 inch. Therefore, any 32 Magnum revolver will also accept and fire both the .32 S&W and the .32S&W Long cartridges. The .32 H&R Magnum cartridge performance level is well above that of any other 32-caliber handgun cartridge currently available.

PF = bull. mass x muzzle vel.

TKO-Taylor Knock Out Formula
