You're going to get mostly answers that say a Judge is a poor HD weapon, and they'll be mostly right. It's a great snake gun with almost any shotshell in it, up to about eight feet.
Actually, I'm betting that, as usual, you will likely get more opinions from folks that repeat what they have heard about The Judge instead of educated and useful opinions from real owners/shooters.
In my case, I have a couple of years of experience with shooting lots of .410 loads as well as .45 Colt. My favorite HD/VD load is home rolled 3" shells (my Judge is the 3" Mag model) with plated lead BB shot, which at
normal HD/VD range of maybe 2-8 yards will totally shred a 12-15 circle, but yet not put those across the parking lot or down the hall at home in lethal jeopardy as an unintended target. What's not to like about being able to accomplish both a lethal defense and provide some safety to others ?
But, I have to agree with the folks that claim, at long range, the spread may become unacceptable. Imagine that, with shotshells out of a 3" barrel........
But to agree with my friend wrs40, The Judge with #6 shot results in some serious death to copperheads or rattlers, if that is how you choose to deal with snakes.
If unintended targets are not a concern, check out the offerings at Paraklese Technologies, as their outside the box loadings for The Judge are pretty bad Mojo. And for sure the .45 Colt is to be respected as well.
Just my 2 cents worth.
