In this photo I am measuring the group, hopefully you will see from the photo that I am not measuring up to the actual hole but to the penetration circumference that you can see if you look care fully, from my calipers it came out at 0.911"


To get your group size you then subtract the bullet diameter from the measured size, in this case 0.287" so if this was a competition card then my entered group size would be 0.624".
You then record this with all the other interesting data on the target, photograph it and post in the scoring thread I will put up. In my example below it doesn't have the competition card marking "FB-UK 2013 Cast Bollit Summer League round 1" along with a witnesses signature, type of sights used should also be entered. In this case it was standard issue front blade and rear notch sights.

The 100 yard targets would be the same except for the scoring, inward, and competition details.
