Re: Would AR400 steel hold up to a 308

Right, which is why I said that for pistols it's not a big deal. Hot mag loads from a 44 or a 454 can cause issues, but even a ringer of a 10mm load still fragments everything up on mild.
I suggested to start out long range with a rifle and move it closer in to see what's going on with it. You have to worry of the jacket coming back at you, a 500y shot won't bring a jacket back.
For 22 rimfire you can use 3/8" aluminum for a gong if you're out past 100y.
