A rifle sighted in at this distance ensures the projectile’s trajectory intersects the point of aim at both the specified range and a further point downrange, often around 100 yards, depending on the caliber and specific ballistic characteristics. This approach allows for accurate shots at shorter distances without requiring significant holdover or hold-under adjustments. For example, a common application is found with .223 Remington/5.56 NATO caliber rifles where the shorter range sighting-in minimizes deviation within a practical engagement envelope.
This sighting-in method provides a practical compromise for maintaining accuracy across a range of distances without needing complex adjustments. Historically, military and law enforcement organizations have utilized this principle for efficient training and operational effectiveness. It simplifies aiming procedures, especially in dynamic situations, while ensuring hits within a vital zone around the intended point of impact. This technique’s enduring relevance stems from its balance of simplicity and effectiveness in diverse shooting disciplines.
