32, is also chambered in .32 S&W Long. The IOF .32 Revolver manufactured by the Ordnance Factories Organization in India for civilian licence holders is chambered for this cartridge. Interchangeability The .32 S&W Long headspaces on the rim and shares the rim dimensions and case and bullet diameters of the shorter .32 S&W cartridge and the longer .32 H&R Magnum and .327 Federal Magnum cartridges. The shorter .32 S&W may be fired in handguns chambered for the .32 S&W Long; and the .32 S&W Long may be fired in arms chambered for the longer .32 H&R and .327 Federal magnums; although the longer cartridges should not fit and must not be fired in arms designed for the shorter and less powerful cartridges. The .32 S&W Long and .32 Long Colt are not interchangeable. At one time it was widely publicized that these rounds would interchange, but in truth it has never been deemed safe to do so.
