The outside dimeter of the case is the same.
So if there is no reduction in size forward of the sizing ring in your die?
The sizing die will work exactly as designed with .32 S&W Long, .32 H&R Mag, and .327 Federal.
Older dies may have a problem with the seating & crimping die being too short??
You will just have to try it and see if it has enough adjustment.
I would expect though, that any .32 H&R Mag die set will work perfectly with .327 Fed., when properly adjusted.
