Just got back from the range. My wife, who I guess I better not P O, shot 5 rounds at 100 yards into one hole measuring .356 with her CZ 22 Hornet. Do you subtract .234 and get a group of .132? Color me confused (and jealous).

  If you measure outside edge to outside edge, then you subtract the diameter of the bullet. Otherwise, if measuring from center to center of the holes, that's what the group measures.

  As stated, subtract 1 bullet diameter from the largest outside dimention.
  However, you can't go by just 1 group you need multiple groups to find out what her (and the rifles) average group is.

  Some guys like a mag full of lead, I still prefer one round to the head.
