Arma 2 Weapon Ranging and Correction Tables

[BadBoy_Killa]

Just wanted to say thanks Malloy, I know you posted
it else where as will, or at least others have copied it
and referenced it to you.

I have done a similar table for the Barrett but boy what a difficult weapon
to make a correction table for! untill 300 meters everything below the range is at
Meters / Mills : 100= +1 150= +2 200= +2 250=+1 300=+1 zoomed
Unzoomed :100= 0 150= 0 200= 0 250=0 300= 0.5

mapped it all the way to 700 but not very accurate although it took me hours
hitting unmoving target accurately.

can't wait to see what you come back with after testing this weapon!
may I suggest going to 1500 meters, this weapon is powerful enough you wont run out of scope

Thanks everyone for your compliments, I will try to continue making as many of these as are neccessary.

I have created ranging tables for the M107, MK12, DMR, and tested the M40. I have found that the M40 ranging and correction is the same as the M24 (at least, I couldn't tell any difference). Here are the word files for each weapons containing the files. I figured this would be easier than posting a picture until I post my complete guide/tables. I have also included a link to the M24 tables so that those not wanting to wait for me to make them more printer/user friendly can modify these.


NOTE: When the variable scopes are zoomed in, the mil-dots appear to be accurate assuming a 2 meter tall target like with the M24. Another thing to be noted here is that the zero ranges for zoomed and unzoomed are different.

DMR Tables
M107 Tables
MK 12 Tables
M24 Tables


Also, for the printer-friendly tables to come in the compiled guide, what details would you want in them and in what order? I was thinking of making them with Target Height, Correction, and then Range. I was thinking about using only height and correction, but I remembered that you might need to know the ranges and corrections for shooting from an incline. Would you guys also want them to list ranges in 50 or 100 meter increments?

[Hoak]

Outstanding and thank you again Daniel! I think your formatting ideas are fine, but would suggest you include 50 and 100m increments as the terrain is rather varied in ArmA II; and there will be some that just want some rough numbers to remember as a rule-of-thumb -- and others who always crave as much detail as possible.

You may also want to compile your final work to PDF, as DOC or RTF files often get edited and/or corrupted before getting passed along... Paste your signature or avatar in there too, I like to remember the folks that put time and effort into something I benefit from.

Either Marines use ammunition with a MUCH flatter trajectory than the IDF, or the in-game ballistics are simply off compared to RL. M24 with standard IDF ammo would require 33 clicks, or ~9.43 mils, while in-game only needs 7, which is a major difference. Hope ACE2 comes to the rescue

[KJGJ]

Thank you very much for this, it helps tremendously.

[BadBoy_Killa]

This is great! thanks again DM!
I agree with HOAK, PDF it so that it is protected, your work is greatly
appreciated just make it will be!

Any chance for Russian rifles tables? personally I am intersted in the Dragunov

[Mr Fenix]

This thread is a revelation. Thankyou very very much Daniel Malloy! I have never understood the first thing about the 'funny marks' in huds and sights in over a decade of gaming .

Ummm, where do I start?

First, what range are you referring to when you say "33 Clicks"? You're probably saying 33 clicks (33 MOA which equals roughly 9.78 mils) from bottomed out. In-game the rifle is zeroed to 250 m so you can't compare the mils from bottomed out to X range with to the hold off (in mils) from 250m zero to 800 m (which I'm assuming is where you got 7 mils from).

Second, the Marines use the M40 not the M24. The M40 can only use 7.62x51mm, the M24 can be adapted to other calibers but typically and in-game uses the same 7.62x51mm.

Third, there is a ton of other concerns aside from bullet's ballistics that will affect the trajectory and thus affect the correction/hold off. Factors like wind, tgt/shooters elevation, hot/cold barrel, eye relief, shooter's hold will all have an effect. Again you can't compare an in-game weapons zero and hold off to a real weapons range correction and assume BI screwed up the ballistics.

I'm not saying the in-game ballistics are correct I'm saying your method of comparing them is completely wrong.

[galzohar]

- It's for 800m, of course.

- While I forgot to substract the clicks for 250m (I was using standard 100m zero), it's only 3.5 clicks difference between 100m and 250m (1 mil), which means the game is still quite a bit off, though not as much.

- The size of a click is 3cm at 100m, which is also approximately 1 MOA. How accurate it is I'm not sure, but accurate enough to not make such a huge difference. Same goes for inaccuracies in the definition of a mil.

- Other concerns are so irrelevant here that I don't know where to start. Sure those things affect ballistics, but not anywhere near the kind of difference we're talking about here. Especially since the values are from tables (both in-game test values and IRL table values) which use both use standard conditions, so a lot of those effects would end up being the same anyway, on top of being negligible.

-M40 and M24 is practically the same thing. The differences are minor. They (the standard-issue, non-modified ones) use the same barrel and shoot the same ammo.

So I'm saying both the in-game ballistics are incorrect unless the US somehow has access to 7.62 sniper rounds with significantly flatter trajectory, which may or may not be true), and that my methods of comparing them, while only 97% accurate, are more than good enough.

In response to making them PDFs, I will be doing that on the final guide after I have collected the other weapon corrections. I will be working on a ranging table for the russian weapons, but I have to figure out exactly how to do it since they use chevrons zeroed at certain ranges. I am thinking of creating them like I did the M203 grenade launcher instead of a traditional "table"... I am wondering if a mod like ACES would be able to write numbers down next to every other chevron with its zeroed range (to be realistic, one would have to be able to change the zeroed range of the weapon. If we couldn't do that, maybe it wouldn't be considered unrealistic to do so)...
