[QUOTE="Centre Punch, post: 85022, member: 3048"] Skip, From an ex benchrest shooter: Identify the edges of your group that are furthest apart and draw a line through the centre of the opposing bullet holes. Set your Vernier on the group so that the edges of the blade form a 90 degree angle with the scribed line at the furthermost edge and take a reading. Record this reading and subtract your bullet diameter, this will give you your C-C group. If you want to, divide by 1.09 to get MOA. Hope the pix will help explain.
