.32 ACP in .32 S&W revolvers - Interchangable?

[TooTech]

In a separate post on this forum regarding a Colt revolver in .32 S&W long, someone mentioned that you can fire .32 ACP in a revolver chambered for .32 S&W long revolver.

Has anyone else done this? If so, how do the .32 ACP empties look after firing? Any worrisome bulging of the cases?

Here's the post I'm referring to:
