Theres some interesting articles written about loading for the 32s. Glen Fryxell I believe, wrote at least one, theres also a number of guys loading for them on the castboolit forum, a search there should turn up results. Id actually like to have one, they would be cheaper to load for than 22 when rimfire ammo was hard to get and scalper priced, especially if one cast their own bullets.

Some of the talk Ive seen, and one reason Id like to have one is as a geezer gun. Partly for practice and fun shooting, and partly as a protection gun if/when the hands cant take larger stuff without pain. I failed to get on the ball and grab a K-32 before they were discovered as collectible. The little hand ejectors sure are cute though. 22 barrels and cylinders could also be rebored for a K frame. Something to keep in mind.
