Take this with a grain of salt, but since you are getting more consistent results with a hotter barrel, the question is "why"? And the answer is that your barrel isn't more consistent when it is hot, it is more consistently hot.

To explain further, your barrel has a wider thermal range from cold bore to shot five, and a much smaller thermal range from shots six to ten.

My advice is to SLOW down, five minutes between each shot. Do two shot groups that way (will take you a minimum of 50 minutes). If the shot groups between the two are the same then your shooting is fine. If the shot groups between the two are different, then we can talk about your technique.
