    If shooting at these ranges it's very difficult to avoid the odd cockup even with all due diligence and thorough preparation.
    Unprepared, uneducated and poorly proficient hunters, such as myself, are also able to make multitudes of cockups at substantially closer ranges too.

At 4 and 500, same thing aim halfway to the left edge, one person with a dialling scope put .2 mil on and called that good.
    Only one guy got the 720, 300 PRC with a sig bdx scope the rest of us ran out of talent at between 4 and 500. A lot of fun and very instructional, as we realized we over estimate wind especially without knowing the actual wind speed and paying scant regard to down range conditions.
    Target sizes, 8 inch at 200, 12 at 3,4,450 and 720 yds and 16 at 500 because the target hanger got confused and wasn't going back to fix it
    I'm surprised a SIG BDX got it done at that range, I haven't seen them work all that accurately past 500+.


    Can't remember the exact podcast episode, I think it's this one but the dude has a lot worth hearing about accuracy in the field and he gets right into the nitty gritty on precision of a rifle and ammo vs practice using it, he had a good one on windcalls in the mountains.

    I've got the 3-18 sierra 6bdx and have shot goats / deer at a variety of ranges, the longest was 475m. Shot target at 500m as well to the check drop. I won't be using it further. I think the thickness of the reticle covering the target is the problem with the bdx compared to the normal long range optics. The wind is always hard to judge. The NW can certainly blow when it wants to.

    Thoughts? it is a physical impossibility that the bullet remains unaffected if you can detect wind. Winddrift can be called "horisontal gravity", meaning it's there every time.

    373 yds. Perfectly still. Allowed for steep slope. Last night. Higher BC 74 grn bullet helps.

    Identify your target beyond all doubt because you never miss (right?) and I'll be missed.
    @Eat Meater as an analogy wind is a bit like water. If you think of your gully as a stream and the wind is the water flow the velocity is lowest at the banks and highest at the middle. As wind is generally invisible in empty space this can be hard to gauge. Basically the higher the bullet travels obove the ground the higher the windspeed is likely to be effecting it.
    Hopefully makes sense?

    Yes makes sense (I also trout fish so the analogy is relevant). It also helps explain some of my issue on the weekend (see my post in the magazine). I assumed the wind was constant across the gap.

    In My ballistic app I always have a 2mile 90 degree wind set in. It just gives me an idea in a light wind what my bullet my do in the slightest puff at my given range. If I think there may be a tiny wind mid gully I will hold half the windage. Means at worst I will still only be half wrong but still a lethal shot I would only use this in a situation like yours where wind is virtually nill. Anything more and I dial for wind
    Practicing in wind also helps

    2mph wind is probably not enough.
    6mph is a pretty standard light breeze, 3mph is probably the minimum most people will start thinking they need to hold for wind.

    If you are only going to write down one wind value make it 6mph. Then you can double if for a strong(ish) wind and halve it for a breeze.

    Long shots

    Wind for me is tricky to read in a hunting scenario cause it always changes. So if the wind is up I get closer, if it’s light I’ll shoot deer out to 820y. I set up a target a few weeks ago as I got a new range finder and wanted to check my drop was on. Target at 800y, I was on a ridge shooting down into a valley, was a bit gusty on the ridge but pretty calm in the valley. Shot a half MOA group so I figured my RF was on. Time to go cull some hinds.
    Last roar I shot 11deer, one stag at 744y and 10 cull hinds between 400-700. I had one shot go too far back and had to follow up, but all the others were one shot kills. One animal went 20y down hill. The others all fell where they were shot. I typically practice at 800y and that’s a must if you want to shoot long range - practice long range.

    Anything inside of 200m probably doesn't need any wind holds unless shooting 223, but you should always be considering it.
    The wind above the gully will always be faster than what it feels/looks, wind also does funny things as it moves around terrain. It'll often be a different direction than what you think and/or contain some elevation elements.

    Most people underestimate the wind, even people at shooting matches where you think they would know tend to greatly underestimate wind. Even having watched multiple shooters previously get mucked around by the same wind...

    Its got me thinking though, whats the general thoughts on the distance you start to allow for wind, and how strong does that cross wind have to be to have an effect

    Thoughts???
    what cartridge and muzzle velocity @Bos?
