If you look at my updated black rain seating depth experiment, you will notice that the graphic contains the measured group data. OnTarget produces a neat software package that analyzes your groups for you from your scanned in target. You can include lots of information so you can refer to it later if needed. You can control the amount of information printed on the page. I am using the MAC version, but they also have a windows version.
It also includes the ability to calculate the center of the group vs the aim point, which is very useful when evaluating high precision rifles for load development.
