typically folks measure as close as possibly the center to center of the two fartherest holes.
However if the results are to be posted on the internet the measurement is taken inside to inside then subtract one bullet diameter and then only measure two of the three shots because the third one was a flyer.



Too true, I love how they never post pictures of these magnificnet groups either.
With all due respects I know that some folks are actually shooting exceptional groups.....but we've all read about some that can't possibly be anythiung but fabrication and in my own experience 1/2" groups can be achieved but indeed rarely..... I suspect well over half the 1/2" groups reported on the 'net are pure fabrication and wishful thinking.
I worked with a guy once that had a 7 Mag that could hit nickels at 300 yards.......until I invited him to the range to prove it....in reality he couldn't produce a single group at 100 yards better than 3"
