Defects of guns are divided into four groups: common defects, defects associated with internal ballistics, functional defects of guns, wear out of guns. 7
8
Common defects: cartridge can not be loaded into the chamber, weak function of firing, strong function of firing, weak shot. 8
9
Defects associated with internal ballistics are delayed gunshot and ignitor primer. Delayed gunshot is caused by: defective primer, lack of strike firing, impaired ignition powder charge, lack of connection with cartridge bullet 9

Each gun has got a certain life. Life(time) of gun is defined in the specification. Life(time) is determined by the number of shots. Examination system quarantees safety and functionality of gun. Defects are result of failure to comply with technical regulations or improper use of gun. 13
14
Gradual reduction in the functional properties of the bore : a mechanical action, a heat treatment, an erosive action, a chemical action. 14
15
Protection of the functional properties of of the bore : construction of the barrel and the bore, construction of cartridge and its material, material of the barrel and the technology, changes in the design of guns in use. 15
