The basic armour-piecing (AP) shot was a solid steel projectile with a hard point, which would simple smash through armour and do damage to the inside of the tanks and its crew, resulting from the splinters and fragments knocked of from the impact. AP shot was satisfactory against homogeneous armour, but tended to shatter when it struck face-hardened armour. To counter this armour-piecing capped (APC) shot was developed, which had a penetrating cap over the point to counter. Since the cap was now blunt a light steel cap of more pointed form was placed on it as a wind shield, leading to APCBC (armour-piecing capped, ballistic cap) shot, the ultimate solid shot design.To deal with harder and thicker armour, tungsten carbide was adopted as the penetrating material. Since it was heavier than steel, it was not possible to make a simple shot, so a core of tungsten was surrounded by a steel an light alloy body to make APCR shot (armour-piecing composite rigid). While this had a high velocity and good armour piecing power at short and medium ranges, its velocity fell off rapidly in flight until at longer ranges. This mean it was dropped in favour of APDS (armour-piecing discarding sabot) in which the alloy sheath was stripped away as the shot left the muzzle and the tungsten core flew to the target flew to the target at high velocity. This was introduced for the 6-pdr and 17-pdr in 1944 and the APDS shot the 17-pdr became the most powerful tank killer in Europe in 1944-45"Fuente: <a href="http://www.btinternet.com/~ian.a.paterson/equipartillery.htm">http://www.btinternet.com/~ian.a.paterson/equipartillery.htm</a></blockquote>
