What does "sighting-in" a rifle involve?

Sighting-in a rifle refers to the process of adjusting the sights or optics to ensure that the bullet impacts the target accurately at a specified distance. This process is crucial for hunters and shooters because it ensures that when the shooter aims at a target, the bullet will hit exactly where expected, improving accuracy and making the shooting experience safer and more effective.

By aligning the sights so they correspond with the point of impact, the shooter can compensate for any discrepancies caused by factors like bullet drop or windage at various distances. This is an essential practice before taking a rifle into the field, as it enhances the likelihood of making a clean, ethical shot on game.

Changing the caliber of the rifle pertains to switching ammunition types, which is unrelated to sighting-in. Cleaning the rifle is important for maintaining its functionality and accuracy but does not involve the adjustment of sights. Improving the rifle's trigger pull affects how the rifle feels when shooting but does not directly influence where the bullet hits in relation to the aim point.
