Measuring groups
 
When measuring groups, do you measure from the center of the bullet entry hole to the center of the other (of course, the furthest from it) or from the outside edge of the entry hole to the outside edge of the other?:confused:

That doesn't mean you're lazy....I'm lazy for just wanting to use a ruler! Cool software.

Measuring center to center is fine for casual target shooting. For any serious competition, measure from the outer-most edge of the bullet smudge to the outer-most edge of the opposite bullet smudge, then subtract the diameter of the bullet. This will give you your group size. There are also some measuring devises that can be used...Hope this helps..

I generally just try to hit the paper. If there's at least three on the paper, it's a group.

One example:
