    While this is my first full year of being trained to shoot long range 700-1100 yards, along with reloading, reading the wind, air temps ect. I have a question on air density and sound travel. When I can hear cars for miles away [light air density] my bullets shoot a minute low a 9 hundred yards, when there is no sound travel to be heard I shoot a minute high, this goes against what i've read, doesn't heavy air slow a bullet? This is usually around sundown.
    Thanks,Jeff~

    At only 100 yards, the air density should have no significant impact. I suspect you have some other problem such as light angle or????.......Rich

    Sorry Jeff! I misread your 900 yards as "a hundred yards". Thats what happens when your eyes start to go:D....Rich

    Do you have one of those neat weather station things to actually measure the air density?
