Doc Posted August 6, 2006 Report Share Posted August 6, 2006 Could someone explain parallax as it applies to scopes? Doc Quote Link to comment Share on other sites More sharing options...
AJ Posted August 6, 2006 Report Share Posted August 6, 2006 Re: Parallax Parallax is an occurance when the scopes reticle is not focused at the same point as the target. The target may appear to be in focus, but the reticle will move as the shooter moves his/her head. US Optics has a good writeup on parallax.

Doc Posted August 6, 2006 Author Report Share Posted August 6, 2006 Re: Parallax Thanks for the link. You're right, they do an excellent job of explaining parallax. This may relate to my thread about head position consistancy. Apparently, if you can keep your eye centered on the optical axis of the scope, even a scope that has parallax tendencies can have the problem minimized. Actually, I believe I have seen this problem with a BSA 3x-9x that I bought recently, and it is really giving me fits. I shoot some pretty good groups, but they seem to move around quite a bit from set to set. I believe it is showing up a combination of parallax problems and an inconsistancy of eye location relative to the scope from one series of shots to the next. Next time I have the gun out, I'll have to check it out. Again, thanks a lot for the link. Doc Quote Link to comment Share on other sites More sharing options...
AJ Posted August 6, 2006 Report Share Posted August 6, 2006 Re: Parallax Yep, it sounds like a classic case of paralax. Sometimes when a shooter is moving around a lot between shots, paralax will show up as large groups. You are correct that consistant head position is key to good groups. This is even more so on a shotgun without a rear sight shooting slugs. Quote Link to comment Share on other sites More sharing options...
