RE: How to measure a group correctly
 

Long range competition measurement is inside of the hole - I.E. - if any part of the bullet hole touches a ring, the shooter is scored to that ring, even if the center or outer part of the bullet hole is outside of the ring.But the truth of the matter is, for hunting purposes, take a ruler and measure the two widest shots from center - if it is under an inch, it is under an inch:-)
