Target for CTC Groups
« on: November 03, 2009, 09:59:39 AM »
Here is a target I made for shooting and measuring center-to-center (CTC) group size.  All are welcome to use it.  Shoot two groups, usually five shots each, at the large cross targets.  Shoot two individual shots at the small cross targets.  Measure the greatest outside-to-outside (OTO) distance of your 5-shot groups.  Measure the OTO diameter of each single shot.  Subtract the average OTO diameter of your single shots from the average OTO size of your groups.  The difference is the average CTC group size for 10 shots (two 5-shot groups).
