When I was shooting competition with the Garrand I let the loaded clips sit in the sunlight if there was any. I don't know how much effect it had at 300m over cool ammunition. I couldn't tell much diffrence in their performance.

The fellow I was talking to the other day shoots a highly customized
223 with very tight groups at 300 yards. He said that he was seeing
elevation differences of 2 to 3 inches between hot and cold ammo.

Wayne That may be with a .223 at that distance. I may have seen or noticed a difference if I was shooting further with the 30.06
