You really can not compare a precision rifle with a battle rifle when it comes to accuracy.
To me poor accuracy with a bolt rifle is anything over 1/2 moa but great accuracy with an M1A IS 1/2 moa. I have not seen many M1As that shoot much better than 1/2 moa, the rifle was not designed to be super accurate, just extremely reliable in truly ####ty conditions, with good knock down power.
