What happens to accuracy when magnification is increased excessively?

Increasing magnification excessively can indeed narrow the field of view. This is a key aspect of how optics work; as magnification increases, the area that you can see through the sight becomes smaller. While higher magnification can make the target appear larger and potentially easier to see, it can also make it more difficult to track the target, as a smaller field of view means that there is less contextual information available. This can lead to challenges in maintaining focus on a moving target and may result in missing the target altogether if it moves outside the limited view.

Additionally, with a narrower field of view, steadiness becomes even more crucial. Minor movements become more pronounced due to the increased magnification, which can negatively impact your ability to hold your aim steady and accurately place shots. Overall, while the target may seem larger with higher magnification, the limitations imposed by the narrower field of view can hinder overall shooting effectiveness.
