This concept refers to the practice of sighting in a firearm at a shorter distance to achieve a desired point of impact at a longer range. For instance, adjusting a rifle’s sights to hit the center of a target at 25 yards can often result in the projectile’s trajectory intersecting the line of sight again at 100 yards. This allows shooters to effectively zero their rifles at a shorter, more convenient distance.
This technique provides several practical advantages. Shorter ranges are often more accessible and require less complex range setup. It also simplifies the zeroing process, as minor adjustments at a shorter distance translate to more noticeable changes at longer ranges, making it easier to fine-tune accuracy. Historically, this method has been employed by both military and civilian shooters to efficiently zero firearms without needing extensive long-range facilities. It offers a practical and cost-effective solution for ensuring accurate shot placement at extended distances.
