When I use Shooter and enter actual barometric pressure or enter the altitude I get two different sets of dope. At 1000 yards I am just under 4, MOA off. When I use the engineeringtoolbox.com and the altitude / barometric pressure chart I use 10000 feet or 20.6 barometric pressure. I can give exact ballistic specifications but at this time I do not feel it is relevant. It is more a difference of getting one read out using barometric pressure and the other read out using exact altitude.
