Sighting in a firearm to achieve impact at the desired point of aim often involves a shorter-range target to simplify the process. This technique allows for adjustments and confirmation of accuracy without requiring a full 100-yard range. For example, a rifle intended to be zeroed at 100 yards can be initially sighted at a 10-yard distance. Calculated adjustments are then made to the sights based on the ballistic trajectory of the specific ammunition used, ensuring accurate impact at the longer range.
This method offers considerable practical advantages. Reduced range requirements make the sighting-in process more accessible and efficient, requiring less space and potentially lowering associated costs. The shorter distance magnifies small sighting errors, allowing for finer adjustments and potentially increased precision at the desired final zero distance. This practice has become widespread among firearms enthusiasts and professionals, facilitating accuracy improvements in various shooting disciplines and hunting scenarios.
