Letter Z Firearms Glossary
A firearm is said to be "zeroed in" when its sights have been adjusted so that the bullet will hit the center of the target
when the sights are properly aligned upon the center of the target. The farthest distance from a firearm at which the bullet's path and the point of aim coincide.
This term is also used to mean the process of insuring that the sights of a firearm are properly aligned so that where they
indicate the bullet will strike is in fact where it strikes.
