Back in the dark ages of the 1970's I fiddled around with non-standard loads. The popular notion was to load HBWC's upside down for close range social work. I'm not sure why, but I rolled up a few and stoked my cheapo Charter Arms Undercover with them to carry duck hunting. Of all the strange problems, we had armadillos rambling around in our blinds and spreads, annoying and distracting. I let one particularly offensive dillo get withing spitting distance before whacking him with the HBWC. It made a real mess, punching completely through the armor plated varmint and stringing entrails out the exit hole. He still ran off, but that was the goal. Very scientific proof test.
