Streszczenie
A simple method is presented for the estimation of the diameter of the entrance bullet holes in military helmets made of laminated composite materials. The novel part of this method includes the use of steel spikes of various diameters as gauges for the bullet’s diameter. It was found that the highest diameter spike, successfully inserted into the bullet hole, gives an indication of the diameter of the bullet. In addition, colour tests for lead and copper are also used for determining whether the hole is from bullet entrance or exit.
