I really like (and needed) that chart. Thanks Chad.

Chad, what is the source of the pic? Seems like it would be a good read for me.

pretty easy if the wind isn't howling... with the right rifle and ammo
Now, first round hits in the wind, like a "real sniper" has to do, no matter what, is above my skill level as a "fairly proficient marksman"

Tim, it's a page from Tony's data book- Storm Tactical heavy paper data book. I recommend his data book for the various pages and info in it.

Here's the full wind page. Here's how I calculate my wind. This came from my personal drop chart when I had an MOA scope mounted on my 308. My scope was moa, so the wind value is also in MOA. Let's take an 800 yard shot. Let's say I have an 8 mph wind coming from my 2 o'clock position. 8 mph times the wind value of .53 is 4.24 moa wind drift. This tells me the bullet will drift 4.24 moa in a full value wind direction. But the wind is coming from the 2 o'clock, so I take 86.6% of this full value, which is 4.24 times .866, which 3.67 moa. The bullet WILL drift 3.67 moa, so I round up or down to the nearest .25, and hold or dial 3.75 moa of wind. Pair that with my drop, and I take the shot. If the wind changes, I change on the fly with wind call.

Thanks Chad. I will order one.

Having shot larger calibers out to 1000 and beyond, this is my next goal. Take my factory Tikka T3X Varmint in .223 and get 100% hits on a 24 inch target at 1000 yards. Actually I really want MOA or better groups at 1000, but I haven't verified if my platform, loads, or even my abilities are up for that. If I do manage it, I'll probably be on here crowing...at least a little.

So true. I've had the good fortune (several times) via a friend of mine up in the TX Panhandle (we've been hunting whitetails up there for 20 years now) to watch the premier sniper trainer in the world in action. He is an amazing talent, and so are his "students" obviously. The wind always blows up there, which is one reason they train and instruct up there. They don't make first round hits every time either, but don't let them shoot twice, believe me. This goes for prarie dogs at 1000m as well. A guy can sure learn alot by just watching and listening.

Here's a video from a few weeks ago. I'm playing around at Jason's with my 308 PBR rifle (parts build rifle) with my 168 BTHP bulk ammo. First round hit on a 2 moa plate (16") at 800 yards. Now, I shoot this ammo A LOT, so I know the drop and wind drift pretty well. If you pay attention in the video, right as I am about to send the round (at about 45 to 46 seconds in the video), you can hear the wind pick up on me. My original wind call was .7-.8 mils of wind. As I'm squeezing the trigger, I hold more wind of about .9 to 1 full mil of wind. The bullet impacted on the right side of the plate. Had I held the .7 or .8 mils, I would have missed off the right side. When I felt the increase in wind and by increasing my wind call at the last second, I was still able to get the round on target. This is what you have to do on the fly with your wind.

I can do it, but didn't happen over night. Went to a training class, purchased a Long Range Rifle .338 Edge from Defensive Edge in Rathdrum, ID. A .338 Edge is a .300 RUM necked up to .338 shooting a 300 GR Sierra Match King bullet., G7 Range Finder, Kestrel Wind Meter, AR 500 Steel Targets, Redding Dies, etc. Can't tell you the $$$ I have invested but it's my thing and my whole family enjoys it. Two years ago my friend killed a cow elk in Wyoming at 960 Yards with it. Yes the wind is the biggest obstacle to overcome but Practice, Practice, Practice.

I get that, but my point was that once you have elevation DOPE down, and you know how to use known inputs to adjust it for varying environmentals, then it's less about experience and more about the science of it. The only real way to get proficient at wind calls is with experience. That was my only point. Certainly there is an experience factor in both corrections, but experience plays a larger part for wind.

the only way to really read the wind is with wind flags all the way down range. ask Judd.

its a guessing game without target pits and wind flags

sniper this

TAP

Not really. I can read the wind with a Kestrel, or I can read the wind by what I feel hitting me in the face. I generally read the wind with the trees and grass, and apply the wind velocity to the direction and make my wind calculation. Wind flags are great, but that's a benchrest technique.

Mirage reading and focus knob turning is how to get wind read. And that takes lots and lots of practice. I'm still learning. Tens of thousands of rounds later, either spotted or shot.

First round hits at long range are in fact possible, see above.

Jeremy saw my best ever cold bore shot last summer. 800 yards, 3-7 mph wind, four inch plate, center. I did not fire another shot the rest of the day.

Hope you at least had a celebratory beer...or three.

Had my best cold bore shot a little over 3 years ago, 790 yards 8 inch rick almost dead center, fired one moe shot that dat, a spike at a little under 20 yards

It was 9 am. Usually a little early for me.

I think I drank an 18 pack for him as soon as I got home.

He didn't just hit the plate. He dead MFn center punched it.

And what is it about target size that causes misses? Put a big fat 24 inch target out there at 800 and I can get a first round hit within a few inches of center most of the time. Put an 8 inch target out there and I'll probably whiff it. Freakin' mind games!

Few inches of center means you could theoretically hit a 6".

Yes, it could be in your head. You have to believe you will hit it, exhale, squeeze, follow through.

I seen 60 out of 60 in a 10 inch a 1000 yards and he didn't win there is more than you think that can do it
