Optimal Eye Relief For Long-Range Deer Hunting?

Eye Relief Considerations

When determining optimal eye relief for long-range deer hunting, consider the type of scope you’re using. A first focal plane (FFP) scope, which adjusts parallax at 100 yards, often requires less eye relief due to its more compact design. In contrast, a second focal plane (SFP) scope, which adjusts parallax at the scope’s maximum distance, may require more eye relief.

Measuring Eye Relief

To measure eye relief, place a ruler or straightedge on the scope’s ocular housing and align it with the scope’s objective lens. Then, place a target or measuring device at the desired distance (e.g., 100 yards) and adjust the scope to focus on the target using the parallax adjustment. With the scope at this setting, measure the distance from the ruler or straightedge to the shooter’s eyes. This will give you the optimal eye relief for your specific shooting setup.

Eye Relief and Scope Type

Different types of scopes have varying eye relief requirements. For example, a high-magnification rifle scope with a smaller objective lens may require less eye relief, while a low-magnification hunting scope with a larger objective lens may require more. Additionally, scopes with a longer eye relief can be more suitable for shooting with a rifle or shotgun, while shorter eye relief scopes are often preferred for handguns or muzzleloaders.
