Here are the images from my first trip with the target. I shot around 75 .223 and 75 9mm at it.
The first ten shots or so ...
The side splatter from those rounds.
The target after shooting. Some minor damage, though I think the 9mm threw more splatter than the .223s
The bottom rails showing some wear but nothing major.
The 3/8" AR 500 steel held up like a champ. I shot from both sides just to test it out.
