Without pics of exactly what you guys are talking about I'm not exactly sure what you mean, but for my big IPSC sized steel plate (AR500 and thanks to the forum guy who made it for me-- can't remember his name) I put grade 8 bolts through the holes and mounted super heavy duty chain to the bolts behind the steel so the only thing that could get hit is the head of a very large bolt or the really heavy chain. Never any trouble so far. I'll try to take a pic when I'm home. I've hit the chains at 600 before, and a Grendel round doesn't even phase them one bit. Heavy bast#%d to set up though.
