RE: Tikka vs A Bolt survey.
For a typical hunter, 2" is about right. If you visit this page more than once a week, then your probably not just a typical "go to the range once a year to sight your guns in hunter". Then if you visit this page much, then you are probably a shootist also. In that case yea 2" is not great at all. If you visit the reloading page along with this one, then 2" is entirely unacceptable. If you just want to shoot a deer, any gun will work with 4" groups.
