vapenror with reffelbomprofil

摘要

The invention discloses a gun barrel with a novel pattern of a rifling curve. The latter proceeds at start of motion from the parabolic curve y=A+Bx+Cx2 and is supplemented with a constant D, to which is added a freely selectable exponent =d. Due to the freely selected exponent as parameter the ridge force maximum can be displaced at almost equal level between the start of motion and the barrel mouth. At the barrel mouth the ridge force drops to a minimum.
