AR 500 Steel and Steel Core/Armor Piercing or 50 BMG
I am looking for information on AR 500 plate steel and how robust it is for handling steel core /AP type ammo or 50 bmg rounds. It appears to perform well on all rifle ammo but I have buddies whom want to try some old steel core/ap rounds on my plate (1/2 in). Feedback is appreciated before I let them shoot at it and ruin my target. Also will it stop a standard 50 bmg.
