Question on parallax adjustment
 

I'm looking for a scope. Not a really great one, but better than the cheapos Ive been using. I have my eye on this one: http://www.midwesthuntersoutlet.com/...%2BJDyOLrQE%3D

It seems to have everything I want except parallax adjustment. Since I don't have a lot of experience with optics, I would like to know how much parallax error there would be at say 400-500 yards if the scope is fixed at 100. Are we talking fractions of an inch that might cause you to lose a benchrest match? Or are we talking inches that might cause you to miss the vitals of a deer or other medium sized animal?

I don't think you have to worry about parallax, especially on a Nikon scope. The older scopes and cheapie 22 scopes had that issue but modern scope are usually parallax free.

Parallax is the apparent movement of the target in the crosshairs when the eye changes position relative to the scope's ocular lens (the eye piece). All scopes, except for true 1x non-magnifying scopes like the Aimpoints have some parallax.

Parallax is really only an issue if you are trying to shoot very small groups or of you are using a very high magnification scope. Even then, if your eye is centered correctly in the scope, you will see little if any parallax, assuming you are using a quality scope. Cheap or poorly built scopes can have quality issues that will result is shifting parallax that cannot be adjusted for.

It should also be said that even if you have a scope with parallax adjustment, it will be useless unless the range to the target is known.

For deer hunting, I would not worry about parallax. Use the money your would otherwise spend on that feature to buy a better non-adjustable scope.
