What is the correct way to measure a group size

If it's an "internet" group you measure centre to centre then discount the flyers. :lol:

I find it easier and more accurate to measure from the edges of the furthest apart holes and then subtract the bullet diameter.

There is an excellent program for measuring and recording groups
http://ontargetshooting.com/

There is a free version there too.

I use OnTarget as well, the free version and it works very nicely, you import an image of your group, scale it with a known distance such as the size of the V and then click on the holes for the calculation. I use it infrequently so I always have to faff around trying to remember how to put the text on but that is down to me not the application.

Yep, thats the way I have always done it.
