[QUOTE="Mikecr, post: 1064766, member: 1521"] You cannot credibly compare atmospheric rules of thumb to GPS measurement(or any other actual measure).. But this isn't about altitude anyway. It's about air density as seen by our bullets, and is only resolved through parameters we measure(Pressure, Temp, Rh). [/QUOTE]
