measuring a group?

[coop2564]

I've recently read three differrent ways to measure a group of shots. Is there a universal way? How do you do it?

[quickdtoo]

Measuring center to center is hard to do, so I just measure from the inside edge of one hole to the farthest edge of the group. Sometimes that's hard to do when the holes are piled on top of each other. I think the official way is with scoring templates.

I always measure outside to outside (ie the farthest edges of the 2 farthest holes, or the farthest 2 points of 1 ragged hole) then subtract the bullet diameter.  This should give you the ctc distance.

 I think Oneshotonekill is right and easiest to do IMHO, which does not amount
 to much.   Marv

Oneshot's method is the one I've seen used most often and is the method I use myself.
