[QUOTE="M67, post: 704068, member: 26259"] As little as humidity means, 1. A bullet drops SLOWER in high humidity, as water vapor is less dense than air. To be exact, it doesn [I]drop [/I]slower, but it loses velocity slower. 2. Humidity means far more in high temperatures than in low. This is because the vapor pressure of water is higher (100%RH is A LOT more water vapor at 30[COLOR=#1f497d][FONT=Calibri][SIZE=3][FONT=Calibri]°[/FONT][/SIZE][/FONT][/COLOR]C than 0[COLOR=#1f497d][FONT=Calibri][SIZE=3][FONT=Calibri]°[/FONT][/SIZE][/FONT][/COLOR]C) 3. 78%RH is the ICAO std. and a good average, it may be 98 in a rainfall, and 50 in a desert, but it hardly amounts to a click. I would say it is more relevant to account for the coriolis acceleration - and FAR more relevant to keep nazi-reloading routines to ensure low ES. 4. And some serious wind-reading skills. I may be a completely retarded wind-reader, but i have shot some at 1000, a lot inside 1000(meter that is) and alittle out to say 1600m, At the long ranges I miss a lot - but for about two reasons. Im talking first-shots here. - wrong/inaccurate wind assesment - bad form by shooter In the beginning i missed to poor ammo, to not accounting for drift, coriolis, pressure, look angle, you name it - but with good data on the ammo and met/env, good dope from last, and lots of practice - i still miss - to Tony Boyers "friend" the wind...
