A rifle sighted in to have its projectile trajectory intersect the point of aim at 100 yards allows for consistent accuracy at shorter ranges with minimal holdover or hold-under adjustments. For instance, a bullet’s path from a firearm with this specific sight setting will typically impact slightly high at closer distances and slightly low at further distances, creating a predictable arc. This precise configuration allows for rapid target engagement within the effective range of the cartridge, simplifying aiming in dynamic situations.
This sighting-in distance provides a practical balance between short-range precision and mid-range effectiveness for many common hunting and sporting calibers. Historically, this distance has proven effective for engaging targets within typical engagement ranges encountered in these scenarios. It reduces the need for complex calculations or excessive adjustments in the field, streamlining the shooting process and potentially improving shot placement. The principle benefits hunters and competitive shooters who often need to make quick and accurate shots.
