A gun barrel should be replaced after about 50,000 rounds, as the rifling becomes worn down, causing a dip in performance. The more of each, the quicker the deterioration. Two main factors influence the progress of barrel erosion: round weight and amount of propellant. 9-mm barrels can be different lengths from 3.5 to 16.5 inches, depending on firearm make. The 9mm bullet can be quite accurate at short ranges (inside of 100 yards), after 100 yards the round slows and drops rather quickly.
