The importance of maximum range stems from the safety rule "Know your target and what is beyond." A bullet from an errant shot or a miss may fly several miles before it impacts the earth. A knowledge of maximum range (as well as what lies beyond the target area) can help a shooter assess whether it is or is not safe to fire.
The following table contains representative figures for the maximum range for many common rifle and handguncartridges. Note that these figures are approximate and are useful for rough comparison only. Variations in barrel length, the velocity level of the load, bullet ballistic coefficient and more will affect the actual distance attained by a particular load in a particular gun under specific conditions.
