   In my experience with guns and archery when I lived in the US there's a   
   certain amount of psychology involved in the grouping and target size.   
   My groupings would be significantly smaller if my target was a bottle   
   top placed in the centre of the target compared to just shooting at the   
   target alone, the distance being the same.   
      
   ----------------------------   
   Targets meant for adjusting sights have small alignment marks but   
   competition ones require real world skills. Center-punching lathe work by   
   eye is similar.

   These are what we trained to hit, quickly, out to 300 meters.
