I have been looking at a nikon prostaff 4x32 fixed power scope,with a parallax setting at 50 yds.How much will this parallax setting effect shots of greater than 50 yds?The scope will be mounted on a win.model 94 in 30-30.This is really a rimfire scope,but the price of 100$ seemed fair.Is there a comparable scope with a parallax setting of 100 yds.I have looked at bushnell banner 4x32 but I dont know what the parallax setting is.
