So I picked up some 1/2" AR500 armor plates in various sizes. They will have a slight downward angle as I'm hanging them to deflect jackets downward. I'd imagine that these can handle any handgun rounds at any distance, but how about rifle rounds? I'd mostly be shooting 308, 223, 7.62x54R, 30-06 - will these plates handle those rifle rounds? At what distances? Might be easier to tell me what I should *avoid*... eg, don't shoot 223 at closer than 50Y, etc... So, anyone know?
