The test was done with the 1 7/8 inch J frame S&W. It was a long time ago but the penetration was very good indeed as I recall. Jacketed bullet, no expansion, high sectional density, and moving at decent velocity, it should have been. I too would have been surprised by decent terminal performance from these rounds but since a reputable firm was selling it I wanted to see.
I wasn't aware of anything but snubbies being made in this caliber so I figured these were designed to work in a short barreled piece. So unless someone has a one-off 6 inch N frame in this caliber (10 rounds?, that would be kinda cool) the .32 H&R Magnum is a pointless round as it stands. As a low recoil alternative to a .22 revolver for the really recoil/blast sensitive user the .32 Long 100 gr wadcutter sure works though.
Ruger makes a GP100 in .327 Mag in an eight shot configuration and a SP 101 .32 Mag in a six shooter. Taurus, Charter Arms and of course H&R made/make .32 Mags as well although quality might be an issue if you were to shoot it a lot.
There are a couple of threads on the S&W forums in which aficionados of the caliber have had .32's and .327's built using a .38 K frame and a .22/.22 Mag barrel and cylinder. They claim the cost isn't much more than a new K frame.
It's a boutique caliber any more. It has it's uses and can be functionally relevant.

.32 H&R Mag is in that nether region occupied by 10mm; there is a large enough user base, enough enthusiasts, and the occasional cataloged model to keep it from vanishing, but it's never going to be "Buy it at Walmart" popular.
I've thought about reaming my 4" 31-1 to take the round. It's not like it has any real collectability to ruin.
Is that a project you'd tackle yourself or would you have it done? I've heard Bowen Classic Arms is the place for this type of work but it doesn't [I]look[I] too hard if one had access to the proper tools. I'm pondering doing the same with my 4" Model 30-1 so any information or nudges (or shoves) in the right direction are appreciated.

If they started making 432s again I'd buy a brace of them to use as BUG guns.
Oi! I need a Gunsmith Bob! Claude Werner came by Casa de Wheeler a few months ago and worked over a few .38's and .357's. Mainly chamfering and we bobbed a hammer and rounded a trigger on a 3" M36. I'd dearly like to find someone with the tools to work on the .32's though.
I look forward to seeing how it turns it should you decide to do the deed.
