ABSTRACT:
In order to improve the service life of prior art gun tubes and to improve the ballistics of a projectile fired through them, the present invention provides a gun tube with an optimized variable rifling which produces a rifling force curve (R(x)) along the gun tube (x) which has an essentially trapezoidal shape with a noticeably reduced rifling force maximum compared to the rifling force curves of conventional constant rifling.
