What is a common distance used for sighting in a firearm?

The most common distance used for sighting in a firearm is 100 yards. This distance is widely recognized and utilized because it provides a good balance between visibility and practicality for various shooting situations, whether it's for target practice or hunting.

When a shooter zeroes in their firearm at 100 yards, it generally provides effective accuracy for different ranges thereafter, especially for calibers that are commonly used for hunting or sport shooting. Many firearms are designed to perform optimally when sighted at this distance, making it a standard practice in shooting ranges and by hunters alike.

Choosing 100 yards enables shooters to take into account factors such as bullet drop and wind drift more effectively, as it represents a typical range for many hunting scenarios, giving shooters confidence in their accuracy both at that distance and closer. While other distances like 50, 200, or 300 yards can also be utilized for specific purposes, 100 yards remains the baseline for most conventional sighting practices.
