My point is that you can't say 3 round groups can't tell us much and then say 2 2round groups did tell us something.I'd agree with you 3 shot groups aren't telling us much, but the title of the thread is cold bore flyers. The user is trying to figure out how to eliminate or reduce the first round flyers.
The rifle is accurate after the first round. It can hit POA after it has fired one round. Any suggestions on how to get the first round to hit POA?
It is my opinion that to solve a problem you need to get more data on it than OP has, and I would start with larger group sizes or at least doing a 5x5 with shot sequence recorded or something where they can track how the groups form over a larger sample.
