M948 7.62x51 "SLAP" - Armor Piercing Ammunition Testing
This video tests the M948 SLAP (Saboted Light Armor Penetrator) 7.62x51mm ammunition using a custom Arisaka rifle. Despite its design for high velocity (4000-4300 FPS) with a tungsten penetrator, aged 1985 and 1990 production rounds failed to penetrate AR450 steel plates. The likely cause is degradation of the polymer sabot over time, leading to instability and loss of armor-piercing effectiveness.
