Anyone interested in a Mover speed and Lead charts?

Here are my charts to measure the mover speed and what to hold for speed at distance. The mover speed chart can be used for any mover/rifle. The lead chart is rifle specific and based on time of flight. IF things are moving faster than 5mph you'll have to do multiples of a number.

How do you have a paper chart for Density Altitude (DA) changes in your dope? Do any of you have a DA sheet in your Data Book?

I have read and been told to have drop charts for every 2000DA change. My home range is usually around 2000DA. This means I need a drop chart for -2000ft, 0ft, 2000ft, 4000ft, 6000ft, 8000ft, 10,000ft. That's 7 pages in a dope book for one rifle. I don't really want to have that many pages for one rifle (yes, I want ONE data Book for all my rifles). With 3 rifles is 21 pages to sift through. So... below is the chart I made for changing DA. Now I have 2 pages, my Home range dope chart with the wind information on the back and a DA dope chart.

Things to Note
  1. Data recorded - at the top of the chart is how I got the DA numbers. This way I can reference how temperature might change the DA as well as the station pressure. (note the comment in the margin about how temp change = DA change)
  2. All of these are at 50% humidity. To keep this simple I had to eliminate a variable, humidity was it. While I think it will effect things more after 1000yds I don't think it has enough variance inside 1000 to worry about.
  3. Wind - The wind row has 2 numbers in it. The 2 numbers are the wind speeds that are equivalent to the wind hold for 2000DA. Example - if I'm shooting at 6000DA, 800 yards - a 7mph hold is 0.9 mils (6mph from 2000DA) and a 12mph hold is 1.6mil (10mph hold for 2000DA) this allowed the chart to re-use 2 columns of information for each DA change and for me to know what my Rifle MPH is at each DA.
  4. After doing this I think the chart will work out to 1000 or 1100 yards. After that a more refined DA chart may be warranted. At 1100 yards jumping 2000DA is a 0.4 mil jump, that's about 16" of change. For an accurate shot I recommend consulting your Ballistic program on the longer shots with changing DA, but these values will at least give you a starting point if you don't have any other information. of you'll need to pin down your true DA and guess between numbers if needed.
  5. I presented this chart in 2 ways. 1st - straight data. 2nd is the plus or minus from the home range value. Doing the 2nd version can help us understand how much DA can really effect our dope. The 2nd if more for informational used and not necessarily something I would have in my data book.

Let me know what you think.

Do you have versions for the various phases of the moon's effect on drop? ;)

THIS IS AWESOME...just noticed this.

Thank you very much.

I’m a little confused. In the wind column, what does 5/9, 6/11...... represent? Is that wind speed or direction?

Always wind speed 90 degrees to my bullet travel. Here is number 3 from the wright-up that explains what those numbers do.

Oh ok I see it now. It’s the equivalent at 2000 DA. It would help if I could read haha.
 
Where can I buy just an empty binder? I just want to add the pdf in thread. Also are the pdf files already scaled to fit a data book?

The book cover I use is a MILITARY NOTE BOOK COVER from tactical notebook covers. I ordered a 5.5x8.5 binder from Amazon and put the two together or you could order the velcro insert that tactical notebooks carries.

These pages on this thread are 8 1/2 x 11 and intended to be folded in half and fit in a 5x8-ish binder I prefer to cut them out around the outline, laminate them back to back and put them in my book.

Here are some photos of my data book. @seansmd
With the wind chart on the back of each chart I can see my dope chart and the wind chart each time my book is open.
Further in the back I have paper for notes or sketching. Field charts for updating data and blank charts to right out charts if I don't have one.
I also have a milling chart laminated and instructions to program my Lisa range finder.

@Jack Master Love what you're doing this these charts. I work with data for work so I appreciate your work here. I was making my own chart based off your work in excel and noticed something that I don't understand.

the 500 Try column for 0.9 * 1.45 comes out to 1.3 the chart has it as 1.4? is this because it's more aligned to Marc's experience or your experience or some other factor i'm not understanding. because i noticed that all the way down that column it's 0.1 different than my math. the 500 true 5.0 and 5.1 try was also 0.1 shifted from the math. there's a couple others as well.

is this trued to a specific caliber or rifle, or again am i misreading this?

please don't take this as being critical, i'm trying to understand.

No it’s because at some point there is a correction and it needs to be increased ie, rounded up. For 308 it can occur at around 600 yds. In addition rounding up is better because it’s always better to miss high than low.
 
That's not it, I completely understand what you are saying but this is not rounding or correction. If you do it in Excel or even with just a calculator you'll see.

Rack - I agree. I too am seeing this. Thanks for pointing it out.
After spending 30 minutes thinking Google sheets can't do math and 3 beers later I finally found what's going on. Its simple, I let the spread sheet carry the decimals in the background. See image below. When the cells are set to show one number past the decimal ya don't see the rounding going on. My sheet is built from the 1.0 Mil line (in heavy boarder) with adding, subtracting and multiplying to the end line.

My Questions will be - Does it matter? After all, this is only try dope. Several guys have used this sheet a reported back that is worked really well. We're expecting the change a 10th here and there to make perfect watermark bullet placement.

EDIT: - I did replace the sheet on the first posting with an updated weaponized math. It does not carry the decimals. This would be closer to what is calculated with a standard calculator or mental math. Still don't think it'll make much real difference.

Thanks man, I agree, I don't think it will matter much. However if we want to truly put weaponized math to the test we want it to match the training.

Again love what you did with the math visually, and such a cool concept Marc and Frank came up with!
 
Awesome job with this thank you. I am trying to fill a range card out for my 22 and I cant seem to be able to adjust yardage On any of the apps that I use? Is there not a way to be able to change the yards? I'm not very computer savvy

No. The yardage are set. We did not make them editable.
 
So you would then plug in the left to right 9 mph wind into your device/app?
Yes. that is one way to do it.
But, if you'er using a device that will turn the angles for you, you could use that rather than this chart. The device will be more accurate than this chart. This chart is for quick wind speed adjustments or reading the wind without a computer to help get a good wind holds. If you have a device, and have time, use it.

For me, shooting inside 650 yards, all of my wind holds are done using this wind rose combined with the Gun "Mile per Hour" Method. Inside 650 yards I don't get out a computer of any kind for drop or wind, its all on paper. Over 650 I might start verifying my paper information with a computer.

Shoot, I didn't realize the capability of my app. Thanks!!
 
Is there such thing as the corrected wind speed for angle chart in KPH for us that use metric or is there an editable version
 
I would probably suggest 6,12,18,24,32
Duh to me! I just recognized this.
This chart does work in KPH. The values in the chart are not based on any unit of measure. They are based on geometry. This chart, the way it is show, will work for: MPH, KPH, meters per second, feet per hour or light-years per day. Any measure of speed can be used. The values in the the chart do not change for what is being measure. If i used 5, 10, 15, 20 and 25KPH the values in the chart would all be exactly the same as the MPH. In the example on the "How To" the 17KPH resultant will be 9KPH.

Brilliant this will be of great value to me. Thanks
 
Here's are some variations of Jack Masters charts. In my data book, they work better, for me, in landscape format vs portrait.

Jack Master and I was in Frank and Mike's last PR class together and had a chance to sit and talk/drink each night after class. The dude is a wealth of knowledge!!

How do you have a paper chart for Density Altitude (DA) changes in your dope? Do any of you have a DA sheet in your Data Book?

I have read and been told to have drop charts for every 2000DA change. My home range is usually around 2000DA. This means I need a drop chart for -2000ft, 0ft, 2000ft, 4000ft, 6000ft, 8000ft, 10,000ft. That's 7 pages in a dope book for one rifle. I don't really want to have that many pages for one rifle (yes, I want ONE data Book for all my rifles). With 3 rifles is 21 pages to sift through. So... below is the chart I made for changing DA. Now I have 2 pages, my Home range dope chart with the wind information on the back and a DA dope chart.

Things to Note
  1. Data recorded - at the top of the chart is how I got the DA numbers. This way I can reference how temperature might change the DA as well as the station pressure. (note the comment in the margin about how temp change = DA change)
  2. All of these are at 50% humidity. To keep this simple I had to eliminate a variable, humidity was it. While I think it will effect things more after 1000yds I don't think it has enough variance inside 1000 to worry about.
  3. Wind - The wind row has 2 numbers in it. The 2 numbers are the wind speeds that are equivalent to the wind hold for 2000DA. Example - if I'm shooting at 6000DA, 800 yards - a 7mph hold is 0.9 mils (6mph from 2000DA) and a 12mph hold is 1.6mil (10mph hold for 2000DA) this allowed the chart to re-use 2 columns of information for each DA change and for me to know what my Rifle MPH is at each DA.
  4. After doing this I think the chart will work out to 1000 or 1100 yards. After that a more refined DA chart may be warranted. At 1100 yards jumping 2000DA is a 0.4 mil jump, that's about 16" of change. For an accurate shot I recommend consulting your Ballistic program on the longer shots with changing DA, but these values will at least give you a starting point if you don't have any other information. of you'll need to pin down your true DA and guess between numbers if needed.

Let me make sure I'm understanding this right. In the second chart your 950 dope at home is 7.5 but at -2000 you would add .5 and your 6/10 wind values become 5/9? Just making sure I'm thinking right. Also 1. Do you see any need to be closer together than 2000da and 2. are your temp/pressure values observed or general. And 3. Thank You for all this.
