I found an unusual problem with me sites, and I am wondering if anyone is expierencing the same thing. I have sat by a few tanks only 20 meters apart. We will shoot the same target, same range(for instance 800). Their site will hit the target at 800, mine will have to be 1600 or a little more. Mind you we have the same tank, same zoom, same rds, but the outcome is the same. I have to shoot twice as far to hit the same target. I am running the Usranger sound pack, if that makes a different). how do I adjust the sites to get the same range, or is there anyway to fix this.
