The 32 S&W long or 32 S&W can be fired in a .32 H&R Mag revolver. The opposite is not true.
The .327 Federal magnum case is 1/8 inch longer and has a chamber pressure of @45,000 psi. The 32 H&R magnum has a chamber pressure of @ 20,000 psi You can shoot .32 H&R magnums in a gun chambered for .327 Federal magnums - but not vice versa
Yes, you can also fire 32 S&W, 32 S&W long, and 32 semi rimmed ACP, and the 32 H & R magnum. This can be found in Wiki. The first answer may have thought you said 357 magnum.
