DISRUPTIVE DEEP FLUTE (DDF) BARREL CONTOUR The Disruptive Deep Flute (DDF) is an external barrel contour designed to significantly reduce primary (blast compression and expansion) and secondary (sinusoidal resonance) wave events in barrels, improving accuracy, reducing heat, and extending barrel life. Using data from the 2024 TACOM HO Finite Element Analysis (FEA) study led by […]
