50 CAL Vs. AR550 Steel Armor Plates!
This video tests the effectiveness of AR550 steel armor plates against 50 BMG ammunition. The presenter duct-taped five Level III/III+ AR550 plates together and fired both XM33 steel core and Hornady 750gr A-MAX loads at them from approximately 25 meters. The initial test with stacked plates showed surprising resistance, with the XM33 failing to penetrate the first two plates and the A-MAX causing significant deformation but no full penetration through the stacked array. A subsequent test with a single plate demonstrated that the XM33 steel core could penetrate a single AR550 plate, bending it significantly.
