32 ACP rimmed
At one point during the Obama years I realized that with my cast bullets, I could reload cheaper than buy 22s. However, my lead source (wheel weights) suddenly dried up and I decided that I really needed a 22 LR equivalent gun that could handle really small bullets.
My first solution was a SP-101 in 327 along with a custom NLG 55 gr bullet mold. It worked ok, but the case was "too big" to be real happy with my mouse fart loads. All of the free space made for big velocity swings depending on powder position.
My next solution was to stub tube a 7.5" 30 cal (from a scrap 30-30 pull) for my TC. I tried 32 S&W short but the cases were too small for me to handle without fumbling a lot.
I deepened the chamber for 32 ACP. The gun shot good, but my 32 ACP brass was not fun to load. The case size was much better than the 32 shorts, but the rims were very inconsistent size from brand to brand and generally smaller than I liked. So I made up a big batch of brass 32 ACP in length but with the same rim dimension as the 32 S&W Long.
With reloaded primers, 1.7 gr TG and a 55 gr bullet I get a great 890 fps load for offhand practice shooting at 30 ft. Last time I figured my out of pocket cost for the materials, it was like $1.80 per hundred.
