Sighting in a firearm at shorter and longer ranges, such as 25 and 50 yards, establishes a precise point of impact, allowing for accurate bullet trajectory prediction at varying distances. This process often involves adjusting the firearm’s sights to align the point of aim with the point of impact at these predetermined distances. For instance, a rifle zeroed at both distances might impact slightly high at 25 yards, enabling it to cross the line of sight again at 50 yards and beyond, maximizing effective range and accuracy.
This dual-range zeroing method offers several advantages. It allows shooters to engage targets accurately across a broader spectrum of distances without needing to make sight adjustments. Historically, understanding ballistic trajectories and compensating for them has been crucial for hunting and military applications. The ability to confidently hit targets at both close and medium ranges provides a significant tactical advantage. This approach is particularly relevant for modern sporting rifles and other firearms used in diverse scenarios.
