Purchased a 6" AR500 Steel plate for our home range and we put it through its paces yesterday, All I have to say is wow that's impressive ! We shot it with .22, 45 Acp,.380, 9mm, 556 and 7.62x54R. Other then 1 hit on the edge with the 7.62x54R (removed a small piece) with a new paint job it will look like new again !! Many more will be added to the range soon ! Nothing like the sound and the sparks flying off steel.
