I had a Ruger SS 4.6" BHG SSM and a 4" SP101 - both in .32 H&RM. All of the chambers were at the max ID for SAAMI specs, so they worked the small brass a lot. The lead was getting hard to find - and as expensive as the easier to find .38 lead. I sold the guns, dies, brass, etc, and bought a 627 Pro - much more better and gooder... seriously. Some of my 98 & 115gr LRNFP lead loads, at nearly 800 fps, wouldn't knock the steel plates down - all of my wimpiest 125gr & 158gr lead .38 loads do so with style.
Note: Ruger dropped the SA & SP-101 .32s due to poor sales - and elected to reream their stash of 3" .32 SP-101s to the newer '.327 Federal Magnum' length - thus recycling some less than stellar selling revolvers. S&W elected to do this with their J-frame 632 - sorry, not for me - the wound hammer spring never seems as nice as a leaf, a la the K,L, & N frames. Besides, I had a couple of years with .32s - that was enough. YMMV.
