This InRangeTV video tests the effectiveness of .50 BMG M2 AP ammunition against hardened AR450 steel plates using a PGM Hecate II rifle. The AP round easily penetrates two stacked 3/8-inch plates, demonstrating immense energy transfer. Standard Ball ammunition fails to penetrate but causes significant damage. The video also provides historical context and discusses modern alternatives.

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.
