A real ss109 Full Metal Jacketed (FMJ) bullet is made of an outer copper alloy jacket covering a softer lead core and has the nominal mass of 3.95-5.18 g. In the modeling, the bullet was assumed to be a single piece (homogenized) with a sharp tip and a total length of 18 mm, estimating the commercial bullets in terms of diameter and mass. ................
