Was wondering this today as I was shooting my Mk12Mod1 with a NF 2.5-10x24 on it at 700 yards. The optic has a 'fixed at 100' parallax with no further method to adjust it. I do notice at distance I can see the reticle moving a bit but was curious as to just how much havoc having such a short, fixed parallax optic is doing on shooting at distances much further than what its parallax setting is to.
Is this basically like setting any optic you have to be parallax free at 100, and then shooting 600 yards with that setting? Or is there something else to this? Why even do this?
