It most assuredly is. Keep your distance close,...very effective. Probably one of my most favorite all around woods bumming guns when small game is the likely fare. All of my kids and grand kids, and many others,..have started their deer hunting with it,...and I am certain I am not the only one. Couple tips though. First: Keep the hinge area clean,..and relatively dry of lubricants. The H&R/NEF's have a nasty tendacy of opening on firing if gunked up or lubed too heavily. Otherwise,..they are built like a tank and run like a good Timex watch,......
Second,...Though they will shoot them, they are pretty light for 3 inch shells. I haven't ever seen the need to run them myself. YMMV.
Good luck, and enjoy that gun. As simple as they are,...they are just plain good guns.
