I have a 3/8" thick 12" diameter AR 500 gong from Safebuilder (member here).
It gets shot at 25 yards with .223 from a 20" barreled rifle.
That's closer than recommended, and I don't do it, but my friends have done it when I'm not there to stop them.
I only use high velocity rifle rounds on it from 100 yards. 55 grain .223, and 95-grain .243 Win. and .308 Win in 150 and 168 grain weights.
It shrugs all of those off easily, not any dimples or dents, UNLESS a round happens to hit right at the edge. Then, it will damage the plate a bit along that last quarter-inch along the edge.
I've never tried a slug on it. I'm afraid it might dent it from sheer mass, not by melting or digging a hole in the metal.
Buckshot should be no problem, even on a soft steel plate.
