This paper proposes a new method to estimate the striking velocity for ballistic limit velocity in MIL-STD-662F. The method from MIL-STD-662F needs relative air density, drag coefficient, form factor, ballistic coefficient for estimating striking velocity. So precedent studies are essential. However, the new method can estimate striking velocity only using measured velocities and distance between the screen and the target. To prove new method, we compared estimation of striking velocity from both the new method and the method from MIL-STD-662F on the basis of datain PRODAS. The new method shows bigger errors in some velocity ranges. But it could still calculate ballistic limit velocity. It also shows smaller errors in most velocity ranges.
