What does sighting-in a rifle help a shooter to determine?

Sighting-in a rifle is a critical process that helps a shooter establish the rifle's accuracy and alignment with the intended point of impact. This process primarily assists in identifying any issues with shooting technique. When a rifle is sighted in, the shooter adjusts the sights so that when they aim at a target, the bullet will hit where they are aiming. Any consistent deviations from the point of aim may indicate that the shooter is not holding the rifle properly, has poor trigger control, or is applying improper follow-through techniques. Thus, sighting-in can reveal potential problems in the shooter's technique, which can then be corrected for improved accuracy.

While color of the sights, wind resistance, and type of ammunition are all important factors in shooting, they do not directly relate to the fundamental purpose of sighting-in a rifle. Sighting-in focuses primarily on ensuring that the alignment of the sights is true to the expected point of impact and identifying any discrepancies that can be attributed to the shooter's performance.
