Steel Plate Penetration Tests: 7.62mm, 5.56mm
This video tests the penetration capabilities of 5.56mm, 7.62mm, and 9mm FMJ rounds on mild steel plates of 1/4", 1/2", and 3/4" thickness. The 7.62mm caliber demonstrated superior penetration over 5.56mm, successfully piercing the 1/2" plate while 5.56mm struggled. Neither caliber could penetrate the 3/4" plate, suggesting it offers reliable cover against these common rifle rounds. 9mm rounds showed no penetration on any plate thickness.
