Quick Answer
While optics differ in quality and brand, they don't inherently change between .270 and .308 setups for whitetail. The primary consideration is magnification and reticle type, not caliber. Choose an optic suitable for your shooting style and terrain.
Choosing the Right Optic Magnification
When it comes to whitetail hunting, a 3-9x magnification range is often preferred for its versatility. This allows hunters to engage targets at varying distances, from 50 to 300 yards. For a .270 or .308, a 1-4x or 1-6x variable power optic can be beneficial in dense cover or at closer ranges.
Considerations for Reticle Type
A mil-dot or MOA reticle is a good starting point for whitetail hunting. These reticles provide accurate holdovers for both close and long-range shots. When choosing between a .270 and .308, consider the bullet drop compensation (BDC) needed for your specific load and terrain. For example, a 6.5 Creedmoor or .30-06 may require more precise BDC adjustments due to their heavier bullets and flatter trajectories.
Additional Factors to Consider
In addition to magnification and reticle type, consider the optic’s durability, waterproofing, and night vision compatibility. A 30mm tube diameter and a solid, one-piece construction can provide added durability for the rigors of whitetail hunting. When choosing an optic, also consider the quality of the glass and the clarity of the image, as these will impact your shooting performance and overall hunting experience.
