For those just now reading this thread, here is the finished guide I have created in the course of this thread. It contains some basic principles of mil-dot ranging and Russian PSO scopes along with ranging tables for the M24, M40, M107, DMR, MK12 SPR, SVD Dragunov, KSVK, and the VSS Vintorez. There is still a lot of useful information in this thread. If you have the time, I recommend you go through it when you can.
Weapon Ranging and Correction Guide
I have been searching the forums for range tables for the various long-range weapons in Arma 2, but to no avail. I have decided to start a thead in hopes that others will post their custom tables.
Here is a range and aim correction table for the M24 sniper rifle. This has been produced with the Steam demo on Regular difficulty (I assume the ballistics model has not changed. If it has, please say so). The following table has been created using the basic mil dot ranging formula, “Size of target in meters times one-thousand, then dividing by size of target in mils to equal range in meters”. Target height has been estimated at two meters and target width has been estimated at twenty-five percent of target height giving us a width of fifty centimeters. Range and target height/width was established using an BLUFOR Soldier (unarmed). Target correction was established using the orange lights on the small road barriers located next to the soldier as targets. All shots and ranges were taken in the prone position with controlled breathing.
IMPORTANT NOTE: The space between the end of the last mil dots (the 4th from the center) and the thick black line appears to be one mil, not point-nine mils. Also, the mil dots are assumed to be two-tenths of a mil in diameter.
If no one else posts any tables, I will create some more when I get my boxed copy later this week (work permitting). Also, should I create a guide in this thread for the M16 ACOG and the SVD Dragunov? These two optics are pretty self-explanitory, but I'm wondering if it would be helpful for people new to these optics to have an introduction on how to use them...
