I have a single shot .410 (shorty) I take with me in the gopher patch. All my .22s are scoped, which makes (oddly) makes it hard to get the quick close in (under 10 yards) shots on the little boogers. A .410 is just the thing.
Also, I went with .410 because I'd read somewhere that you can fireform spent .303 brass into brass .410 shotshells, which can then be reloaded indefinitely, and I tend to accumulate spent .303 brass (among my gun "issues" is an Enfield "issue"). Been messing around with that off and on all summer, and long story short, it does actually work quite well, once you get the swing of it. Now I can reload my "custom" .410 brass for around 15 cents a shell by harvesting powder and shot from cheap 12gauge target shells. I could go even cheaper than that if I bought powder and shot in bulk. (one 12 gauge shell is enough powder and shot for two .410 shells, for about about a dime per .410, plus roughly a nickle for a primer).
