20mm VS AR500 Steel
This video tests the penetration capabilities of a 20mm armor-piercing tracer round against a 1-inch thick AR500 steel plate. Despite the massive caliber, the 20mm round failed to penetrate the steel, surprisingly showing less penetration depth than a .50 caliber AP round previously tested on the same target. This outcome is attributed to the larger surface area of the 20mm projectile and the extreme hardness of the AR500 steel.
