Before posting my ideas, I must say that I haven´t played arma/dayz that much YET, so for example I don´t know if there is a distance measurement device in dayz or not. Also I haven´t tried every sniper rifle in dayz, so I´m not sure what kind of systems there is available. Please tell me about the distance measurement etc. I´m a military trained sniper myself and I have few insights on this matter. Shooting long distances (depending on weapon/bullet/scope) should be difficult. What I would like to see is that you could have laser distance meter to measure distance. After that you would need to adjust the scope to match the distance and after that you could hit your target. Maybe some scopes/guns could be unaccurate when you get them, so you would need to shoot couple of test shots to adjust the scope to be accurate. I think if you apply wind (not to mention rain / air temperature / rotational error) to the equation, hitting over 500m would be quite difficult. Last competition I was in we had 11g bullets (7,62) and we shot at 730m with 7m/s wind. There were 163 competitors and 7 people (including myself) hit the 730m target. Even without wind hitting on a moving target over 300m away, i´d say is very difficult. BUT, that being said, you can run fast and change directions instantly when running on this game, so hitting that kind of target is obviously more difficult than in real life. That´s why sniping/shooting shouldn´t be 100% realistic. We make our own bullets and compete in competitions similar to SEAL troops or green barets. I know all the information is available in the internet, but I´ll gladly give you guys information about sniper rifles / ammos if you need it. I´ll try to find some sniper rifles in the game (and watch youtube-videos) so I can try the system myself.
