Shooting in my 3006 today at 100 with 165 Partitions at about 2850.
There was about 20mph wind coming mostly from behind and over my right shoulder at about 4 to 6 o'clock.
I put 5 in an inch group at 2" high, which is where I wanted. Ill let yall tell me what the horizontal likely was.
Im good to go with it and I hope so cause Im about to be toting it around for 14 days. But I am curious and I figure it would be a fun one for yall to talk about. Im not really up on this and wouldnt dream of talking about wind drift at the distances some of yall shoot.
If yall want to expand the question out to 200 and 300 yards go ahead.

90deg 10mph is roughly .5” so 20mph would be about an 1”
45 degree angle would be .5”
<45 degrees means <.5”

Fed premium lists their 165 partition at 2830’fps muzzle. With 1.7 inches drift @ 100 with a 90 degree 20 mph wind. Pending the wind angle anywhere from .4 to 1.2 inches.

Rear quartering wind, I'd say about 1/2 inch to the left.

2 inches if you didn't flinch.

Without running through a ballistic calculator, and without having any previous dope, I would guess less than what would matter at 100 yards. Less than 2" at 200 yards, and less than 4" at 300.

Unless the gun's off, Paul's answer should be pretty correct. 0" -.75" or you need to shoot it again.

Not enough to matter. Probably not enough to see in a 1” group. I bet the center of that group didn’t move more than 1/4” with a variable wind from 4 to 6 o’clock. Probably what was more noticeable was the group size slightly opening up.

At that wind angle it may have moved the group 1/4" to 1/2" at 100 yards. It may not have moved the group at all.

That wind angle at 500 to 800 yards is not going to cause a big wind hold. In fact, a 5 mph wind at 3 or 9 o'clock will cause a larger wind hold than a 20 mph at 5 o'clock.

I don't like to guess, I like to calculate! A 4 to 6 o'clock wind is a big swing. Let's say it was 5 o'clock, which is a 50% of full value. For a full value wind, the bullet will drift .8" for a 10 mph, so 20 mph would be 1.6". If it was 20 mph from the 5 o'clock, it would be 50% of full value, so the bullet would drift .8" left. If the wind was more 4 o'clock, then it would drift left 1.4". (.1.6" times .866).

Once I learned this wind clock and the percentages on it, my first round hits went way up at longer ranges. I calculate to 1 mph on all my dope charts. I have a bullet drift value in mils for 1 mph. I figure out the wind speed and direction, and do the math (often times in my head), and apply the wind hold in my reticle. It's that simple. This method is much more precise than guessing and is pretty easy to calculate when you break it down.

I saved one of those you posted quite some time ago Chad, that’s what I was working off of.

I really appreciate the feedback guys. I agree with most that its probably not enough to matter but I was curious to understand the concept in case it mattered for future considerations. Im trying to up my game on this ballistic/shooting stuff so trying to learn.

Chad, I really appreciate the chart. I guess the wind pie chart thing is generic but the list is specific to my situation.
Ive seen many charts for my 3006 through the years but Ive never seen one show only a 4.9" drop at 300 when 2" high at 100. More like 7 to 9".
Am I interpreting something incorrectly on your example???

Edit: never mind you are talking about chads. I only thought I knew why chads was wrong 🤣

Double edit:

Welcome! Sorry, I had the G7 BC entered as the G1. I fixed it. If you are 2" high at 100, your true zero is 215 yards. I've never been a big fan of the "Hunters" zero, but it works for some shooters.

Chad, I know you and others are not a fan but its very good for most of us. Thanks a lot for the chart. Bobo too.

I looked at it three times, and thought I found difference , ha missed that one.

I did opposite last week At 500. Had g1 instead of g7 and was .8 MOA high, I couldn’t figure out why🤣, then got home and figured it out

Yes. I'm loading all the 243 Win ammo for Night Crew and their hunting videos. They run a 55 grain Nosler Ballistic Tip and it's pushing ~3900 fps. They sight in high at 100 yards to be able to hold MPBR on coyotes out to 300 yards. It's point and shoot out to 300. So it does work. I just prefer the mil holds for exact distances on my rifles.

The difference in Chad and Bobos charts seem a fair amount different. Somewhat with the drop but mostly with the wind. Any ideas?

The difference is environmental. Chad probably has his set to his local range(elevation, temp. Etc) and mine I just used generic sea level. my wind is set to 90 degree 10mph.

I also used g1

One chart says at 300 the drop is 6.6 and other is 7.05, so not much.
One chart says at 400 the drop is 21.1 and other 21.72, so not much.
On wind one says at 300 drifts 7.7 and other is 5.06, so a good bit of difference to me.
On wind one says at 400 drifts 14.2 and other is 8.56, so a big difference to me.

Could environmental make that much difference or is one chart just more correct for whatever reason?

I ran another chart in a different program, and I came up with .8" for a 10mph full value cross wind. I'm not sure why there's a difference.

I would “assume” that all those charts could be different just cause of human error on input or it’s just an in exact science.
Just seems the difference at 400 on wind of 14.2 vs 8.56 is too significant to be unexplainable.

It's 100% exact science. You want to calculate any holds for drop and drift. If I know the wind speed and angle, I'll be on target at any distance. I missed a pig at ~1660 yards up on a cliff in the canyons in West Texas. The wind call was spot on, but my range estimation was off about 30-40 yards. The bullet went directly over the back of the pig by about .5 mil. Had I been able to get a laser reading on him, I'd have drilled him. We were already set up and shooting to a mile no problem (7mm-300 Win Mag with 195 Berger).

Here's the Hornady ballistics drop chart

If you say it’s an exact science then I believe you.
Assuming it’s an exact science then why does one chart say 14” drift at 400 and another says 8.56”.
As far as I can tell the input data is the same.
One chart almost has to be wrong.
I’m not disputing your knowledge but asking you to share it with me.

Without running the data and looking at the numbers specifically, what they are saying means ballistics is a experimental game. As with any experiment, the numbers are dang reliable for things that are easy to figure out and when you can minimize variables. Gravity and mass are pretty easy to figure, speed is also, however, some of the data is variable such as temp, baro pressure, etc.

If the variables are inputted incorrectly or if the variables are off by a certain amount, or the ballistics coefficients are different from one to the other, then the numbers become different as the experiment is ran.

The ballistics calculators are simply a theoretic experiment though. the experiment doesn't come to reality until you shoot and verify the data to be accurate.
