S&W Model 36-1, 3" barrel. CCI snake load to the head at about 12 feet. I carry the three-incher a lot when I'm working around the farm. I keep the first chamber up loaded with snake loads. This one was in my yard, about 10 feet from the back door, and maybe 60 feet from my dog pen. I killed this one's twin a year earlier, literally stretched across the bottom step. I did that one with a 12 gauge. I've got a bunch of rat snakes and common king snakes on the place, and they get a pass. Not old No Shoulders.
