 | | The flow type at the bullet's surface changes from a laminar boundary layer at the forward region of the bullet, which is characterized by parallel stream lines, into a turbulent flow, beginning at the cannelure. |
 | | For a 9 mm Luger FMJ pistol bullet, moving slightly faster than the speed of sound (see figure) one finds the following significant differences: the Mach cone is still present but no longer attached to the bullet' s tip, and the opening angle of this cone has increased. |
 | | Finally, for a cal..32 ACP pistol bullet, moving at a speed considerably below the speed of sound (see figure), all shock waves are absent, and what remains are the turbulences behind the bullet's base. |
