If I sight my scope in a barometric pressure environment of 26.8 inches of mercury, and climb until I reach a place with a barometric pressure of 18.9 inches of mercury, what will be my new zero?
Then, if at 18.9 inches of mercury I readjust for the original 250yd zero, what will my new drop at 550yds be, given that the 250yd zero with 26.8 inches of mercury gave me a 47" drop?
Load is 7mm Hunting VLD at 2,780fps.
Thank you for your help.
