Just wanted to say that the quality of your steel is top notch..I had the privilege of shooting at my friend Mike Stang's range and even from 50 yards running 5.56 your steel performed flawlessly with no damage at all.
Thanks for the review Mike.
Plates will usually get small pits at close ranges with high velocity rounds. We have found no way to avoid this. Expect to replace your plates after awhile if you are going to use them for close range rifle drills and be careful.
