I have a Nikon P-223 scope on my MSR. I can zero it in dang good at 25 yards, but if I keep the same settings and go to 100 yards, I don't even hit the target. Nikon says the parallax is 100 yards. I've been reading about parallax and I'm still more confused about it than a homeless guy on house arrest. If I set it for 100 yards, I cant hit anything at 25. I don't think you're supposed to adjust for that little variance in yardarge, are you? Also, when looking through the scope, I can either see the target clearly and lose sight of the crosshairs or if I can see the crosshairs and ther BDC, the target is fuzzy, but I think that is my eyes. Heres 60 rounds at 25 yards..
