Ruger Single-Seven 3.75" .327 Federal Mag Stainless Revolver

A: From Wikipedia. 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 H&R and Federal magnums; although the longer cartridges should not fit and must not be fired in arms designed for the shorter and less powerful cartridges.

A: Robert, yes in addition to the 327 Federal Magnum you can fire 32 H&R Magnum, 32 S&W Long, 32 S&W, and 32 ACP through this revolver.

A: Both. The 327 Fed Magnum round is the most powerful of the 3 , but all will work. I hope that helps.

A: Robert, yes Sir, it will successfully fir both rounds. I have been doing just that for years with nary an issue.

A: Teh .32 S&W is often used in this firearm, for two reasons - one, it is less expensive and two, it has less recoil.
