WEZ hit rates.

[huntnful]

I bought the Applied ballistics pro version app so I could play with the WEZ portion. It’s pretty cool to play around with realistic and unrealistic numbers haha. If anyone wants me to punch in numbers for them and their specific rifle/use case and post a screen shot of their data, it only takes a second. I’d be happy to do it.

You can select the target size and yardage. I have a 10X14” rectangle for a broadside elkish sized target.



Uncertainties (the MV is your SD)

What info do you need? I am building a 4lb 556 and a 6lb 6.5c. I am curious how they will stack against my 8lb 6.5prc and 9lb 300prc.

I don’t see anywhere that I can input recoil level with this app. That would be a nice addition though.

Just looks like precision and SD as far as actual rifle related info is concerned. Then the load data. Bullet, MV, ect. The entries I posted in the picture is the only info I can input. As well as change target dimensions

How bout same inputs you have but move distance to 600 yds, precision to 1.5 MOA and a 147 ELDm @ 2700 FPS.

Let’s see the Rokslide special.

223
77tmk
2700fps
1.5moa
450 yards (~2k fps mark)
Deer sized vitals 10x8

Remember, these inputs are meant to be 2SD, so likely need to be larger than what you're showing on your screencaps.

Also, even if you input 0 wind, the wind direction matters since there is scatter on wind speed. Here is an 800yd run on your target from a real 28 Nos with 0mph mean crosswind:

Also FYI this is more like 1842fps using the AB CDM.

I’m not sure what input it is, but on one of the podcasts Form was talking about wind calling and hit rate differences between a good wind caller to a so so wind caller. If you could show what a wind call within 4 mph looks like compared to a poor wind call at maybe 8-10 off. Maybe with 147 eldm @2700 and 1.5moa

Also, what’s the cost to unlock WEZ?

 

[solarshooter]

The screencaps I showed were with a 4mph 2SD wind error. This means that 19 times out of 20, you can call wind within 4mph. Form and I disagreed on this definition in the past, I am now certain I am correct that WEZ inputs are the 2 SD levels. However, Form's point was that effectively the 2SD threshold for novice shooters is more like +/-8mph in broken mountainous terrain.

I'll run that combo you asked about in a second. Cost is 30$ for the app, then a 3-4$ per month subscription for Pro which gives you WEZ. It's extremely cool in my opinion, if you have everything set up correctly, as you input range and wind it tells you your expected hit percentage real time. Very powerful.

Here is the test case you asked about, on the original 14x10" target, now plotting hit rate as a function of range, for a 4mph 2sd wind call:


And an 8mph 2sd wind call:

Very nice! Looks like you’ve spent some time with the app already! It very new to me. But 30 for the SD on your inputs? That would be an insanely terrible SD for any decent ammo?

Saw a couple boxes of Hornady match run about that recently

Again, that is 2x my actual SD of 15fps. Which comes from a sample of 35 rds, and is therefore reasonably high confidence. Number of samples matters when quantifying these things, just like with group size.

Okay I gotcha now! Makes sense!

Now say the wind is blowing 10 MPH.

When I enter 4mph in the WEZ, does than mean I’m within 4 MPH higher or lower (6-14mph)

Or when I enter 4 MPH is that 2MPH from each side of the 10MPH (8-12MPH)?

It means that 19 times out of 20 (95% of the time), you will be within +/-4mph. So example 1.

Appreciate the clarity!

This is not my understanding from reading the link posted, using the app myself, and looking at the low/medium/high inputs AB uses as default.

Can anyone confirm if the entry for the Leica shot probability analysis in their range finding binos should also be entered as 2sigma? Their online video is a bit vague.
