Understanding the Needs of a .308 Long-Range Scope
Magnification for the Task at Hand
The ability to see your target clearly at significant distances is, of course, paramount. However, the appropriate magnification level is often debated. For effective long-range work with a .308, a starting point of at least a minimum of five or even six-power magnification is a must. This allows for proper target identification and assessment, particularly when coupled with a large objective lens.
Variable magnification scopes are the ideal choice, offering shooters the flexibility to adjust the magnification depending on the distance and conditions. For example, a scope with a magnification range of 5-25x or 6-24x will be highly versatile, allowing the user to dial down the power for closer targets or low-light situations and dial up for maximum detail at extended ranges. The ability to zoom in and out easily is something you can appreciate as it greatly impacts a shot’s success.
Lenses and Light Gathering
The size of the objective lens, the front lens of the scope, plays a pivotal role in the performance of your scope. A larger objective lens diameter allows more light to enter the scope, resulting in a brighter and clearer image, particularly in low-light conditions like dawn or dusk. While a larger objective lens is advantageous, it also tends to increase the overall weight and size of the scope. This trade-off needs to be considered when selecting a scope for your .308. If you often shoot in dim environments, a larger objective lens is essential. If weight and bulk are major concerns, a slightly smaller objective might be more appropriate, but never sacrifice objective size to the point it impedes your abilities.
The Importance of the Reticle
The reticle, the crosshairs or aiming points within the scope, is fundamental for accurate shot placement. There are several different types, each offering its own advantages. Reticles with MOA (Minute of Angle) or MIL (milliradian) markings are common in long-range shooting. These markings, often referred to as hash marks or dots, allow shooters to accurately compensate for bullet drop and wind drift. MOA reticles divide a circle into 60 minutes, while MIL reticles divide a circle into 6283 milliradians. Knowing your reticle type and using it to adjust for these factors is critical to long-range shooting success.
Illuminated reticles, where the reticle can be lit up, are advantageous in low-light conditions. They make the reticle easier to see against dark backgrounds, significantly improving target acquisition.
Precision and Adjustment Mechanisms
The turrets, the dials used to adjust the scope’s elevation (vertical) and windage (horizontal), are critical for compensating for bullet drop and wind drift at long ranges. They need to be precise, repeatable, and easy to use. Look for turrets with clear, tactile clicks, indicating the amount of adjustment per click (usually ¼ MOA or 0.1 MIL). A zero-stop feature on the elevation turret is incredibly beneficial. This allows you to quickly return to your zeroed position without having to count clicks.
Durability and Build Quality Considerations
Long-range scopes are often subjected to harsh conditions, so robust construction is vital. Look for scopes made from high-quality materials, like aircraft-grade aluminum, and that are sealed to be waterproof and fog-proof. Make sure the scope can withstand the recoil of your .308 rifle, as inferior scopes may not withstand the repeated impacts.
Additional Features
Parallax adjustment, which allows you to focus the image on the target at different distances, is an invaluable feature for long-range shooting. This adjustment eliminates parallax error, ensuring your reticle is aligned with the target, no matter your viewing angle. Eye relief, the distance between your eye and the scope’s ocular lens when the image is clear, is another key consideration. Adequate eye relief is vital to avoid injury from recoil and to provide a comfortable shooting experience.
