[QUOTE="dfanonymous, post: 2276301, member: 97050"] You missed the quoting me. You say you can, but when it comes to first round impacts at these ranges on any given day it’s not what I see in the real world. It’s not what any professional shooter does. It’s not what the military teaches. It doesn’t work by itself. I never said I don’t use mirage. I said not by itself. Again, even if you the little reference card[ATTACH alt="4F4FB24B-4AE8-4DC0-AF06-08F0F3FE691E.png"]295172[/ATTACH] It’s a range of wind. As you get more wind, you get more broad of a range. If you’re off by 1 mph at say 1000y, you off by at least .2 mils or about 7 inches with a good .308. Not horrible but not great. Target size dependent. But that depends on wind being constant, and it’s not constant. So even if you time the shot, you can expect that 7 inches to be more like 7-9 inches as assuming you shoot 1/16 moa. Lol So again, I know for a fact that you’re not making first round hits at a 10 inch target (human head) beyond 1000y with mirage alone. Especially with wind that exist out west here. Yes, the kestrel will give you a base line of wind at your location to THE MPH. That’s 1/3 of the solution. That takes the guess work out of that. Where the art comes into play is the rest of the 2/3. Is the center range wind the same as wind at your position? If the mirage shows the same direction and about the same speed then I’ll use the kestrel’s wind and move on to the the target wind. However, usually there are other issues more advanced shooting over a depression, where you might worry about an updraft depending on the primary wind direction. The target is where your mirage is more useful, especially at the mile and two miles shooting competitions this is more critical. Verifying wind direction and getting a estimate on wind speed using mirage, vegetation (note), terrain and compared to you’re baseline with the kestrel. After that, a lot comes down to experience. The terrain does matter because if you’re not use to shooting in a single area, and you don’t have mirage to rely on, more tools and understanding is useful to figure out what wind is doing closer to the target and the mid range. You’re comparing being on a mountain side you never been on, to a range condition that you have immense experience with…that’s not what I’m talking about. Note on vegetation, I would know where you are and how vegetation moves. A good way for those that have time is to go to predominate brush and measure it with the kestrel while looking at how it moves, and maybe write it down on a notepad. A Joshua tree moves pretty much not a all compared to bitter brush at 10 mph. [/QUOTE]
