Just wondering how to measure group size. I have always measured the widest hole spread. Which if I put stacked five on top of each other I'd have the width of a .22. How is it that I have read some groups of being less than .22? I'm presuming they are subtracting the width of a .22 to get sub .22 numbers. Is that the correct way to measure?
Thanks,
Chad
