Years ago when I goose hunted on the Texas Gulf Coast prairie, I carried a little Charter Arms .38 Spcl Undercover snubnose loaded with hollow base WC's loaded upside down, loaded to mid-range velocity, not target. I had a problem with armadillos and possums crawling through my blind in a drainage ditch. Those HBWC's made a real mess at short range into tough armadillos. I'm pretty sure they tumbled and upset in the dillos before exiting with a big spray of dillo innards. They probably weren't as good as modern bullets, but they did the job cheaply at short range.
