I think we'll start to see coriolis effect playing a part in our hold. Our target is North to South with a slight Westward aim. We had a half mil left hold on wind that seemed to be right at our back.

Interesting you mention Coriolis Mark as I was just reading up on this. Wind in Strelok was off that day I was out so I started looking into it. Turns out it was an error on my part; usually is. At my spot, I am shooting east which causes the round to hit high. Engaging the option to account for Coriolis only changed the come up from 18.3 to 18.1. Not sure what I was expecting but I surprised it was that small an amount.
This was only my second time out shooting at that distance so definitely much to learn. I can see a Kestrel in my future though.
I never thought about East/West, that's pretty interesting too. I started thinking about coriolis a year or so back when I noticed the right side of the target stand took more of a beating than the left after years of shooting 1300 yards.

I would have thought more too. Elevation has more impact than the C effect. We are shooting at 1250. On the hide folks usually include elevation with DOPE because Denver is not Phx. And it matters. I shot high over on Elk my first shot at 1300 because I was up in the mountains. I think it was slightly over .5 mil, dialed down and smack.

Most guys these day use DA which literally incorporates everything else, then they factor in temperature to determine their muzzle velocity secondary to powder’s temperature sensitivity.

Density altitude. It is a measure or air thickness...it incorporates pressure, altitude, temp, humidity, etc into one measurement. It originates as a value in aviation, but the same output applies to external ballistics.
It can be the ONE value of concern for the shooter to encompass all variables exerting force on the bullet, given you know muzzle velocity and accurate BC.
