In most shooting applications, a 20 MOA (Minutes of Angle) scope base provides sufficient elevation adjustment to accommodate a wide range of shooting distances and environmental conditions. It’s a practical choice for many shooters engaged in various types of shooting, including hunting and general long-range shooting.
However, for those involved in serious long-range competition shooting, where extreme distances and precise elevation adjustments are the norm, a 40 MOA scope base can be invaluable. It allows these shooters to maximize the elevation range of their scopes, enabling them to make extremely precise adjustments and achieve accuracy at distances that would otherwise be challenging.
The choice of MOA value for the scope base should align with the specific shooting discipline, the rifle, and the intended distances. Serious long-range competitors often benefit from the extended range offered by higher MOA bases, while other shooters may find that a 20 MOA base suits their needs perfectly for a variety of applications.
