Just curious as to why you want a single shot, instead of a Bolt action?? I mean if you get a well named brand, remington, browning, winchester, they are the same price basically. Of course depending on what you get, some single shots more that bolt actions, some bolt actions more than single shots. But bolt actions are nice and more diverse, you may not think you ever need a quick second shot in close shooting conditions, but when you do you will wish you had it. PLus bolt actions shoot just as good as single shots......... Anyways if i had to choose between shotgun barrel or single shot I would pick single shot, i love accuracy.
