With the new patch, accuracy is not an issue anymore. Mosin, long range scope,bipod, minimum fov, 2x2 inc sticker on the door, from 800+m away, dead center every time. Think the new attachment realy aproves accuracy. Zombie headshots 800m+ away are easey, cuz if you set your cross hair on center of the zombie head(max zoom posible, lr scope with minimum fov), and wait 3s, you will see that even 800+m away the crosshair actualy does not move outside the parameter of the zombie head. Its super easey :) About judging distances. It shouldnt be a problem, unless you know about 40 perfect sniper positions with 360 degree views.. And you dont :) I found there are only a fev realy realy realy good positions for snipers, usualy only one per town or a certain area. Yes, one. Not 6 or 14. One perfect spot, where you see them, they cant see you, and you have 98% cover from all sides, exept the spot you use to take your shots and you use for observing the area. Balota. Cernogorsk. Zelenogorsk. NE airfield. NW airfield. Berezino. Tried about 5 places on each, found the best spaces. And once you have your sweetspots, you should make practice shots on each of the target areas. I usualy try to pick a wall, that has some marks on it. Try to hit a certain spot, on each of the buildings you are going to snipe, till you get a center hit. BE WARNED: Map distances (klick to one point, and then another) is probably acurate, but i found it that if it says 280m, dont go for 300 scope setting, stay on 200 and try a fev shots. It works for me like a charm. Allso, LR scopes. If not ruined, try it on your mosin, even if its badly broken. Most of the times, they are not actualy broken, and are like pristine. See trough is perfect, and there is no accuracy issues on 800+m.
