How many rounds have you shot thru your Judge?
Just a guess, but somewhere around 200 Coyboy 45Colt, 40, or 50 45 Colt JHP. Winchester PDX1. 50 or so 410 buckshot, and probably 50 410 birdshot, or more correctly snakeshot.
Certainly not as tight as my low round count circa 1972 S&W Model 10, but as tight as my Ruger LCR.
Accuracy with 45 Colt is well within what is needed for SD, Federal 000 Buckshot holds a nice "group" I would call it because with one pull of the trigger there are 4 holes in about a 3" group pretty much point of aim @ 10 yards. 3 pulls, 12 holes all center mass. With 45 Colt the group is even better.
There is no reason that the S&W Governor wouldn't do as well.
And for twice the price you get one more round!
Rifled bore makes a sorry pattern.
Nope, not in my experience with Federal Handgun 000 buckshot as mentioned above. The other myth is shallow rifling leads to poor 45 Colt accuracy. Again, not in my experience.
Now birdshot, no, I'm not going to try my PD Poly for upland game. But @10' or so, #7 1/2 shot provides a pattern that will really ruin a Copperhead's day!
