Quick Answer
For long-range .338 Lapua hunting, consider optics with high magnification (24-40x), a 34mm or 36mm objective lens, and a first focal plane reticle for accurate subtensions and bullet drop compensation. A 5-10x zoom ratio and parallax adjustment are also essential for quick target acquisition and precise shot placement.
Optics Requirements for Long-Range .338 Lapua Hunting
When selecting optics for long-range hunting, the first consideration is the magnification power. For .338 Lapua hunting, a high magnification power of 24-40x is necessary to accurately engage targets at extended ranges. However, higher magnification also increases the sensitivity to movement and atmospheric conditions.
Reticle Selection and Design
A first focal plane (FFP) reticle is ideal for long-range shooting, as it provides accurate subtensions and bullet drop compensation. The reticle should also feature a mil-dot or MOA grid for precise holdovers and windage adjustments. For .338 Lapua, a reticle with a 1.5-2.5 MOA dot is recommended for quick target acquisition.
Objective Lens Size and Zoom Ratio
A 34mm or 36mm objective lens is essential for long-range shooting, as it allows for a larger exit pupil and reduces the affects of atmospheric distortion. A 5-10x zoom ratio is also necessary for quick target acquisition and precise shot placement. This range of magnification provides a balance between low power for close-range shots and high power for extended ranges.
