Assume a rifle is being fired that shoots with the bullet drop table given in Table 1. This means that the rifle sight setting for any range from 0 to 500 meters is available. The sight adjustment procedure can be followed step-by-step. 1. Determine the slant range to the target.
Many modern iron sights are designed to be adjustable for sighting in firearms by adjusting the sights for elevation or windage. [2] On many firearms it is the rear sight that is adjustable. For precision shooting applications such as varminting or sniping, the iron sights are usually replaced by a telescopic sight. Iron sights may still be ...
