Sight setting refers to the adjustment of the sights of a firearm to improve accuracy. There are many synonyms that can be used to describe this process, including zeroing in, aligning, calibrating, adjusting, and sighting-in. Each of these terms refers to the same process of setting the sights to improve aim and accuracy. The process may involve making slight adjustments to the sights such as moving them up or down or left or right. Proper sight setting is crucial for accurate shooting, particularly when it comes to long-range shooting. So, whether you use the term zeroing in or aligning, the goal is the same- to hit the target with precision every time.
