FIELD: barrels of small arms and guns. SUBSTANCE: blank face in a rifled barrel is made in the form of an arc of a circle united with the arc of the bottom of riffles, and the effective face is made in the form of an arc of a circle that is tangent to the circle of fields or to the circle of fields and arc of the blank face. When bullet is moving in the bore, rotary motion is imparted to it due to the contact with the effective face and part of the field, which decreases the wear of the effective face and break-through of powder gases. EFFECT: improved design. 3 dwg
