those three shot groups look great man! You are getting consistant 3 shots under an inch. With all the heat and energy that a 30-06 generates, you really would need a varmint or bull barrel to maintain those groups over 3 shots. If you have the time, and feel like experimenting, I bet you could wait about 10 minutes between all 5 shots and they would be under an inch. Shoot 1, wait 10 min, shoot 2, etc..... so that essentially all of your shots are cold bore shots.
