Longrange, I do not know about the first shot. Always heard that the first shot/clean bore might be off a little. I am not sure that I want to try it again. I can tell you, that day after shooting 100 yards I went to the 500 yard range and went 3 for 3. I brought a guy to the range that has never shoot 500 yards and really did not shoot scope rifles and he went 2 for 3..
CAfool68, I made the dope correction but have not been back to the range with that gun
