The .410 in a judge is worthless for hunting. There's no choke and the spin of the rifling insures no pattern past 20 feet or so. My .410/45 colt barreled contender, OTOH, has a full choke that screws on and it also has straight grooves to stop the shot cup rotation as it passes through. It will actually take things out to a full 25 yards. I've shot birds on the wing, a rabbit last year at about 17 yards paced out on the run, and even done some clays shooting, though I didn't eat 'em for lunch. For back woods survival, it trumps the judge IMHO and I can always carry my .30-30 scoped barrel or my .22LR match barrel along in the pack.
That .45/.410 is a fun gun to goof off with, but seriously, for a survival gun, I'll want a long gun, preferably a shotgun along. I have a 20" Spartan 20 gauge SxS that's perfect for that, open choke in the slug barrel, modified in the shot barrel, you have a combination gun for big game to small. You could get the same gun in 12 gauge if you wanted more umph in the slugs. It's really my dove gun, but it's sort of a multi-task gun, home defense, doves, survival, whatever.
I see the judge at its best as an apartment self defense gun loaded with buckshot loads. I never saw it as anything I'd want in an outdoor gun. The .410 is just pretty much worthless in the field and the excessive free bore limits, somewhat, accuracy, though my Contender barrel shoots about 8 MOA, 2" 25 yards, which ain't too bad, really. But, my Blackhawk is a whole lot better, twice as accurate, and it's a smaller, lighter gun.
