The bullet-firing test was done in the different velocity and collision angle of the bullet. The effect of its velocity and angle on the deformation shape after firing was discussed by comparison with experiment and simulation. The velocity of the bullet was chosen in several kinds of speed ranges at 80m/s-250m/s. As for the angle of incidence with the collision object, four kinds of angles 90°(head-on collision), 45°, 30°, and 60°were set.
