The confusion arises because people don't just want to see the target they want to be able to see their bullet hole. Assuming a reasonable size target - say centre mass - then, of course, a 10X is perfectly sufficient. A smaller target - say F Class V Bull - ought properly to be viewed through a scope with greater magnification but not necessarily through one that will allow you to see your bullet holes as that work is better left to a spotting scope.
While I do use a 8-32x56 on my best rifle, it is fair to say that a 6-24x50 scope of good quality should be more than adequate to see targets clearly at almost any distance one is shooting at.
