my scope is zeroed perfectly and numbers 1 through 5 match perfectly, but after that the line lines start to not match up. by the number 10 it's off by about half a line. has anyone else had this problem? I believe its tracking correctly and that it is a problem with the lines on the cap rather than the adjustment value because the lines get closer again and by the time I'm back to 0 or 20 minutes basically 1 revolution. I called nightforce and of course they will take care of it but I have to send it in. from the sounds of it they have not heard of this problem.
