Take my 6.5, for instance, at my home range: 8.7 at 1,000 minus 5.8 at 800 equals 2.9 Mils of drop in that 200-yard gap. If I take that 2.9 and multiply it by .45, it gives me 1.3 Mils. Add that to my 800-yard data of 5.8 and it gives me... guess what...? What my TRASOL spits out for my 900-yard data!


8.7-5.8 = 2.9.


2.9 x .45 = 1.3


5.8 + 1.3 = 7.1 Mils


7.1 Mils to a water-line hit


This was great. Problem solved at 900 from now on, and it saved student ammo and instructor aggravation. I could now concentrate on the student’s wind call knowing that the data I gave him was elevation-correct, minus his input and windage. And it works in MOA or Mil, of course. I had created voodoo.

Interesting approach, I'm making note of these factors for future reference.

 

[slayer 2c]

Thanks for this. I added it to my DataBook pages

 

[A&8's]

Good read. Gonna sit down later this eve and compare cals to math DOPE.

 

[opus56]

Thanks for the data.

still wont help you on a plate at 300 though Frank

900 has to be 1.22 and 1000 to 1.20 for it to work on my 6.5.

It’s something to tweek on till you have it down for your ‘s. Like reloads

 

[Dthomas3523]

It’s not meant to be perfect.

It’s just a fast way to get students on steel who don’t have software.

 

[Timetoshoot]

Trying to simplify my work flow at matches I’ve gone back ti using paper dope sheets with 50yard intervals. This works for finding shots between my data points. 147 eldm @ 2740
1000 to 1500 I’ve been using .4
500 to 1000 I’ve been using .45
And inside 500 I’ve been using .5

I seldom miss due to elevation on 2 moa or bigger. Oh I definitely miss my fair share R&L.!!

 

[slayer 2c]

Thank you for this Math, really helps with friends at the range!!!!

Question and I apologize in advance if its been asked before, I see a high speed number and a low speed number, but both of these numbers are no where near my numbers for fps. Any idea on how speed effects the results. I see tweaking and I know its just to get on steel I'm not looking for centered hits. But 6.5 for example is only running 2650's I got to assume that's gonna through off the math!!

 

[Lowlight]

we see more variation in the shooter than the MV.

This is from the data we record from the class and their shooters, we monitor their dope

You can always plus and minus it a touch if you need it to line up too a different speed.

 

[slayer 2c]

Thank you!

Have a buddy coming out to shoot this week. He just a hunter with no real “math” experience when it comes to shooting.

I had @JC Steel build a truing target like the one Frank has posted.

Gonna start at 300 and work back in 100yd increments and use this method to get his dope for his 6.5.

How far are you working back with Marc’s method?

 

[Dthomas3523]

How far are you working back with Marc’s method?

1k for this rifle.

It lines up within .1-.2 of my verified dope to 1200 on my 6cm though.

Is that truing bar 4” wide?

 

[Dthomas3523]

Is that truing bar 4” wide?

5.75” tall. 3’ wide I believe is what was spec.

I’ll have to measure to verify for sure.

 

[slayer 2c]

I need to order some steel!!

 

[Outcome]

This is gonna help me so much with my friends who shoot MOA. And I lines up well with my slow
.308

Glad you guys are enjoying this. Amazing what a bottle of Bulleit Rye and a calculator can accomplish. :-]]

I used Mark's math over the weekend for a friends brand new AI in 6.5. It was spot on out to 600 yards. We started at 300 with 1.0mil had 10" steel circle at 400 and the math put him on it first shot. A minor adjustment to center line and some quick math put him on the plate at 500 with the first shot again. Again a quick adjustment to center line and some more math and solid hit at 600. All in all we had good data for that rifle within 1 box of ammo. Not only was it easy and effective it was a cost savings as well!!!!!

This is a great tool.....I've copied all the numbers and put it into my data book to use later. I know its just a matter of time until I go looking for it again.

Hi All

How can this formula be updated to work in Meters?

 

[Lowlight]

it will work the same, just use the dope via meters,

should still work, just use the X Factor

 

[danatkins]

So can this be used for dope at 200 as well?

 

[Lowlight]

200 is a pretty standard value,

if you cannot hit 200, time to get a new hobby.

.5 Mils is the basic, 2 MOA with just about any caliber, the fine tune will be for location and MV

But you should be within an inch of 200 just using 2 MOA

 

[danatkins]

Just wondering. Finally got a load that my rifle likes so time to start doping it out.

This is awesome stuff, thanks!

@lowlight

In another thread you posted your weaponized math work sheet. Could you please post it either here, or in "Resources" to make it easy to find?

Edit: Nevermind, found it.

 

[Ratchety]

Gents, I am curious how the weaponized math might apply to meters. I could directly translate 600yds to 548m, 700yds etc, otherwise I don't see the percentages lining up correctly.... What says you?

Just replace yds for m. It’s not a perfect science, it’s to get you very close and then true.

Thanks for the reply TacticalDillhole.

METERS -
Just found this post.
I'm betting that if you add 9% of each factor to that factor, it will put you near center plate.
Correct me if I'm wrong. Didn't do the math, Just figuring that's gonna be close.

[jcomar1]

Thanks i've been looking for this!

 

[Tylerm713]

For us simpletons, I'm guessing this would also work in MOA? If so, I created the attached table to convert everything over, if someone wants to check my work. Each cell won't match exactly to the Mil table, but I used a middle benchmark row and worked back from there.

 

[Lowlight]

Correct,

Mils or MOA does not matter, both can be interchanged using 3.43

 

[Tylerm713]

Correct,

Cool, I'll put this table to work then (instead of carrying the mil table and needing to convert each one on the fly). Hope this helps anyone that's using MOA instead of mils.

 

[Tylerm713]

@Jack Master looked it over, and it looks like I had a formula error. This one is (hopefully) correct.

 

[ACard]

Recently introduced a friend to the fun of shooting steel at range and we have been assembling a Tikka T3X Tact in 6.5 CM for his first ever bolt gun (at 70 yo) for him. We were able to get solid DOPE out to 800 last week. This week we decided to stretch his legs a little and were shooting 3 MOA tagets on the line from 300 to 1K. we had no dope at 900 and 1K so i verifeid his DOPE at 600-800 and then dialed in his come up for 900. I have never been so pleased! The first round he sent was an absolute dead center punch on the steel! Truly amazing! Verified the DOPE with 4 more rounds and then repeated the process with precisely the same results at 1K. I cannot tell you how gratifying that was. Many, many thanks to you Mark for sharing this nugget of wisdom!

 

[Gr1m]

I have attached a excel doc with the weaponized math and added aditional worksheets for Mils, TMOA & SMOA. both are setup for yards and meters. Based on Marc's @Enough Said 9% (9.4%) correction for meters. If i have messed up the math, please let me know. I have added to the side of the table the correction factor used to get the figures. Hope this helps.

To make it even, take your rifle/load parameters out of your kestrel first. Weaponized Math needs none of that. LOL

I would love for someone to break this down with crayons for me because I keep getting questions about this.

[Lowlight]

It's been over-explained at this point, if you can't understand it, or follow the simple chart, maybe consider golf

 

[Moe Ron]

5 out of 4 people have trouble with math.

 

[Lowlight]

There really is no "math" you can just read the chart Ted created

if you use 1.0 Mils to hit 300 yards, Point of Aim, Point of Impact,

moving to 400 you start with 1.7 Mils, after shooting and determining point of aim, point of impact at 400, you use that number to give you the 500 yard starting point.

it's trued and verified data, that fills in the blanks for you, it's gravity, not bullet weight, BC, muzzle velocity, sight height, twist rate, bullet length, azimuth to target, it's just gravity, that is it, you use the confirmed data from the previous yard line to line up the next 100 yard target.
