What (and how far away) can I shoot at 3/4" AR350 plate?

My dad had a little scrap 3/4" AR350, just enough to get two 8" targets, and I was just wondering if anyone knew what calibers I could shoot at it (and at what distances) without messing up the targets.

I'm guessing it'll be just fine for lead bullet handgun stuff but am not sure about rifle....I see that most rifle stuff is made out of AR500 but I thought maybe at longer distances it might be ok but i'm not sure. I have a .223 but since I've only got the two targets I don't really want to do any test shooting and potentially ruin them.

The targets are made to hang from a stand so we put an attachment point on the back of them so they angle downwards like 20 degrees when hanging. I thought maybe with the downward angle, the fact that they'll be free swinging, and that they're thicker then normal plate targets it might be ok for rifle but I'm not too sure since every rifle target I see is made of AR500. For rifle I just want to be able to shoot FMJ .223 at it from 100+ yards

Ive shot my half inch plate (Ar350 Several times with FMJ 223 from 100 yards away. It makes a huge crater in the plate. FMJ 308, 30-06, and 7.62x54 knockes holes clean through it all the way out to 300 yards.

I dont know what the extra 1/4 inch would do. but i doubt it would make that much of a difference.
