    Please verify for me that the following will get the most accurate results:

    1) Using the G7 BC provided by Bryan Litz for the Nosler 165gr. .308 Accubond

    2) Using a corrected barometric pressure of 30.06, I should have the altitude set to the actual shooting altitude of 6000' AND check "Pressure is Corrected"

    3) Using the actual temperature (my guess is yes) rather than the calculated temperature from the sea level standard of 59, i.e. 59 - (3.6 * 6000/1000) = 37.4

    Thanks,
