IMHO bolt guns tend to be easier to make accurate. Most single shot (non bolt) rifles require some tinkering to get them to be accurate. Some of us tinkerers love the challenge, some guys just want to buy a rifle and know its going to shoot exactly where they want without all the fuss.
In the field in common hunting situations either can be a good choice.
PS at some point all hunting guns are single shots....you shoot one time, you load and shoot again if necessary.
