I have a Vortex Viper 5-15x44 (the discontinued Midwayusa special). The optics are decent enough, but the parallax setting seems to be way off. Sharpest focal setting to my eye yields a parallax setting much shooter than the distances I'm shooting at (off my a large factor, like well under 100 yards setting for actual 300 yards). I am familiar with how to set the reticle adjustment in the eyepiece, and have done it both with and without my glasses to the same effect.
I know that on cheaper optics, the markings may not quite line up. Granted, this is no Nightforce, but I am surprised it is off by that much. My concern is what the actual parallax is set at. Is it indeed set for the sharpest/correct setting, or would the correct parallax for, say, 300 yards be at the 300 mark on the focusing knob, even if that doesn't yield the sharpest focus for me?
