Shooting Tip - Scope Parallax

Published on March 26, 2012
Duration: 2:04

This video explains scope parallax error, a common issue in long-range shooting that affects accuracy. It demonstrates how apparent reticle movement occurs when the shooter's eye is not centered, even with a stable rifle. The solution involves adjusting the scope's parallax knob until the reticle appears stationary relative to the target, ensuring both are in the same focal plane for precise aiming.

Quick Summary

Scope parallax error is the apparent movement between the reticle and target image when the shooter's eye is off-center. To fix it, adjust the scope's parallax knob until moving your head causes no apparent reticle shift, ensuring both are in the same focal plane for accurate long-range shooting.

Frequently Asked Questions

What is scope parallax error and how does it affect shooting?

Scope parallax error occurs when the reticle and target image are not in the same focal plane. This causes the reticle to appear to move relative to the target if the shooter's eye position changes, leading to inconsistent point of impact and larger group sizes, especially at long range.

How can I fix or eliminate parallax error in my rifle scope?

To eliminate parallax, adjust the scope's parallax knob (often labeled 'focus') until the reticle appears stationary relative to the target, regardless of slight changes in your head position behind the scope. This ensures both the reticle and target are in the same focal plane.

What equipment is shown in the video for demonstrating parallax?

The video demonstrates parallax using a steady Caldwell Shooting Supplies rifle rest and a Protektor Model leather sandbag. The scope featured is a Nightforce G7 5.5-22x50, mounted on a rifle chambered in 7mm Rem Mag.

Why is checking scope parallax important for long-range shooting?

Checking scope parallax is crucial for long-range shooting because even small errors can translate into significant misses at extended distances. Properly adjusting parallax ensures that your aiming point remains consistent, maximizing accuracy and shot placement.
