Abstract. Four types of light-armour piercing ammunition were fired against mild
steel, high hardness steel and ceramic faced composite armour targets.
The ammunition included three types of 7.62x51 mm AP and
the 30-06 APM2 (7.62x63mm) projectile. The penetrative capability of the
ammunition was assessed in terms of both the ballistic limit
velocity and the ballistic limit energy. The 7.62x51 mm FFV
projectile, which has a tungsten carbide core, had the lowest
ballistic limit velocity against all target types. The three steel
cored projectiles (Hirtenberger, P80 and 30-06) showed variation in their
relative performance dependent upon target type. Examination of the ballistic
limit energy showed that the sharper pointed projectiles performed better
against strong targets. However, against weak targets, blunt projectiles performed
better as they promoted plug formation and shear failure in
the target. This was in agreement with the calculated loads
to initiate penetration. For the ceramic-faced targets the Florence analysis
[1] was found to produce reasonable agreement with the experimental
results when the effects of both the projectile core and
jacket where taken into account.
