Abstract
A gun barrel with piecewise helical barrel fluting comprises a single start non-stop feature of alternating and intersecting right hand and left hand helical segments. Piecewise helical barrel fluting combines the ease of manufacture of a single start fluting with the improved performance benefits of a multi-start approach, namely increased barrel stiffness and resulting performance with respect to firing accuracy and firing precision.
