Ive heard that Savage uses the Nikon prostaff on their package rifles but I am suspicious of that because Ive had two of these scopes and both were excellent optics. They both were labled "prostaff" yet the package scopes aren't.

Most centerfire scopes are parallax free at 100yds and rimfire scopes at 40yds. Maybe yours wasn't set at any particular parallax setting. Just suppose it is parallax free at 235yds because the factory skipped this step during mfg.? This could cause an easily identifiable parallax problem.
Aim yours out the back door and see if you can tell where it is parallax free at.
