The optimal sight-in range for a .308 rifle depends on the intended application and the shooter’s specific needs. It represents the distance at which the point of aim and point of impact perfectly align. For example, a 100-yard zero means the bullet will hit precisely where the sights are aimed at 100 yards. Different zero distances affect the bullet’s trajectory, influencing its arc and the amount of holdover or hold-under required at other ranges.
Selecting an appropriate sight-in range is crucial for accurate shooting. A properly zeroed rifle ensures consistent shot placement within the desired effective range. This enhances hunting success, improves target shooting performance, and maximizes the cartridge’s effectiveness. Historically, military and civilian applications often employed different standard zeroing distances based on typical engagement ranges and the need to balance point-blank range with minimizing holdover at longer distances.
