Re: hha 0pitimzer
Do not disregard the little one word question from Len Backus. Although he does not go into any detail to explain what he's stating, he is right on the money.
What Len means is that when you change your distance to the target, if you do not correct your parallax adjustment for each different distance you are shooting, this will through your point of impact way off center.
I understand you may be dealing with a scope alignment problem and that will require the rings that Buzzard Bait has recommended, but once your scope has been properly shimmed and aligned, if you ever experience the problem of POI changing for an unexplainable reason, it often relates to ones Parallax not being properly adjusted for the change in distance.
Darn - Just imagine how much everybody would learn if we could just get Len talking more???
