My Raging Judge with a 6 inch barrel. Shooting from a rest with 454 I can group 6" at a 150 yards and 10" groups at 200 yards with open sights. I never ran 45LC through it so no info there. With 410 slugs i get 4" groups at 75 yards. The firearm is probably a better performer than i can shoot. My brother and I can tell no difference when shooting comparable caliber wheel guns in accuracy.
