[QUOTE="Loner, post: 386169, member: 24560"] Temp. and alt. change the real world bc of any bullet. So alt. or barometric pressure can be used to adjust your calcs. Most programs will cancel out one when the other is imputed. Higher humidity will increase the bc slightly but I don't usually see enough of a change to worry about it. None the less your program should have a humidity field as well. [/QUOTE]
