At what magnification does parallax matter?

If you going to shoot beyond 300 yards and use a 12x or higher magnification scope, parallax needs to be considered. Until scope magnification started exceeding 10x and we started shooting regularly beyond 300 yards, we did not have to be concerned about parallax.

What is adjustable parallax scope?

A side focus parallax adjustment modifies the riflescope’s parallax, making the reticle appear clearer and have less perceived movement when you’re shooting at different distances.

Do all rifle scopes have parallax adjustment?

Parallax correction is a feature available in nearly all modern rifle scopes. The effect of parallax is presented when your reticle appears out of focus with respect to your target, and to the focal plane of the scope.

Do fixed power scopes have parallax?

The main difference between the two is that the fixed parallax has the parallax set to a specific distance, while it can be set on different distances with the adjustable parallax. Riflescopes that feature a fixed parallax, which is set on a specific distance, have a parallax error on all other distances.

How much does parallax affect accuracy?

At short distances, the parallax effect does not affect accuracy. Using the same 4x scope at 100 yards, the maximum error is less than 2/10ths of an inch.

What does parallax at 100 yards mean?

Most sporting rifle scopes are set to be Parallax Error-Free at 100 yards. That is, when aiming through your scope at a target 100 yards away, the point of aim stays the same regardless of the position or movement of your eye (side to side or up/down).

Do you need parallax adjustment for hunting?

It depends on the distance you will be shooting and the magnification. If you are shooting a 3-9x scope out to 300 yards you can probably do without side parallax adjustment. If your over 300 years or more than 9x magnification, I would recommend side parallax.

What does 100 yard fixed parallax mean?

Scopes with fixed parallax offered the best resolution only at one distance (100 meters/yards) at which the target was in focus. At all other distances, the picture was less sharp or even blurry.
