If i made a steel backstop plate to shoot at, say 3'x3' and angled it in 45 degrees, how thick should it be?

My uncle had a steel plate for a backstop when I was a kid. IIRC, it was 3/4" steel. Manganese steel would be better, but can ruin a shear. It should be flame-cut.

The question shouldn't be just "how thick?", it should also be "how hard?".   AR500 about 0.5" thick at a 45 degree angle would probably last hundreds of thousands of rounds if you're shooting .223 at it.

Halfinch of mild steel or more, and 5.56mm will wear it out. BTDT.
