Rifles are capable of shooting .5 or so MOA best case - but wind, and field shooting make that extremely hard to do.. And the target moves as well.
If you can rationalize saying you can hit a vital zone that matches something like that - it's not skill - it's denial
Again- there is a difference shooting in a war, for hunting... There are plenty "to whom it may concern" shots in a war - throwing one of those at an animal that has to live for a live with the results that you don't... ... Well you'd better hope God, Karma or whatnot doesn't return the favor.
