First of all, congratulations on scoring a great revolver in a great cartridge! It's one of my favorites, and I have owned one in one iteration or another since 2001. It's easy shooting and very terminally effective when loaded correctly. I have a the same revolver and recently took delivery of one of the new 4 5/8-inch barreled .480 models. I'm anxious to hear your shooting impressions!
