Abstract: The ballistics testing results according to VPAM APR 2007 are represented in this work. Ballistic testing was done using .308 Win 7.62 ´ 51 FMJ/FB/WC ammunition. Two different cartridges from the producer Nammo AP 8 and Ruag SWISS P AP were used. Both types of ammunition have tungsten carbide core. Damage – craters, done by the projectiles, were cut and analyzed over the transverse section by optical and scanning electron microscope. The EDS analyses of the characteristic areas were also done.

Key words: ballistic test, armour protection steel, ammunition, W carbide core.
